Amlogic specific extensions to the Synopsys Designware HDMI Controller
|
||||
======================================================================
|
||||
|
||||
The Amlogic Meson Synopsys Designware Integration is composed of :
|
||||
- A Synopsys DesignWare HDMI Controller IP
|
||||
- A TOP control block controlling the Clocks and PHY
|
||||
- A custom HDMI PHY in order to convert video to TMDS signal
|
||||
___________________________________
|
||||
| HDMI TOP |<= HPD
|
||||
|___________________________________|
|
||||
| | |
|
||||
| Synopsys HDMI | HDMI PHY |=> TMDS
|
||||
| Controller |________________|
|
||||
|___________________________________|<=> DDC
|
||||
|
||||
The HDMI TOP block only supports HPD sensing.
|
||||
The Synopsys HDMI Controller interrupt is routed through the
|
||||
TOP Block interrupt.
|
||||
Communication to the TOP Block and the Synopsys HDMI Controller is done
|
||||
via a pair of dedicated addr+read/write registers.
|
||||
The HDMI PHY is configured by registers in the HHI register block.
|
||||
|
||||
Pixel data arrives in 4:4:4 format from the VENC block and the VPU HDMI mux
|
||||
selects either the ENCI encoder for the 576i or 480i formats or the ENCP
|
||||
encoder for all the other formats including interlaced HD formats.
|
||||
|
||||
The VENC uses a DVI encoder on top of the ENCI or ENCP encoders to generate
|
||||
DVI timings for the HDMI controller.
|
||||
|
||||
Amlogic Meson GXBB, GXL and GXM SoCs families embeds the Synopsys DesignWare
|
||||
HDMI TX IP version 2.01a with HDCP and I2C & S/PDIF
|
||||
audio source interfaces.
|
||||
|
||||
Required properties:
|
||||
- compatible: value should be different for each SoC family as :
|
||||
- GXBB (S905) : "amlogic,meson-gxbb-dw-hdmi"
|
||||
- GXL (S905X, S905D) : "amlogic,meson-gxl-dw-hdmi"
|
||||
- GXM (S912) : "amlogic,meson-gxm-dw-hdmi"
|
||||
followed by the common "amlogic,meson-gx-dw-hdmi"
|
||||
- G12A (S905X2, S905Y2, S905D2) : "amlogic,meson-g12a-dw-hdmi"
|
||||
- reg: Physical base address and length of the controller's registers.
|
||||
- interrupts: The HDMI interrupt number
|
||||
- clocks, clock-names : must have the phandles to the HDMI iahb and isfr clocks,
|
||||
and the Amlogic Meson venci clocks as described in
|
||||
Documentation/devicetree/bindings/clock/clock-bindings.txt,
|
||||
the clocks are soc specific, the clock-names should be "iahb", "isfr", "venci"
|
||||
- resets, resets-names: must have the phandles to the HDMI apb, glue and phy
|
||||
resets as described in :
|
||||
Documentation/devicetree/bindings/reset/reset.txt,
|
||||
the reset-names should be "hdmitx_apb", "hdmitx", "hdmitx_phy"
|
||||
|
||||
Optional properties:
|
||||
- hdmi-supply: Optional phandle to an external 5V regulator to power the HDMI
|
||||
logic, as described in the file ../regulator/regulator.txt
|
||||
|
||||
Required nodes:
|
||||
|
||||
The connections to the HDMI ports are modeled using the OF graph
|
||||
bindings specified in Documentation/devicetree/bindings/graph.txt.
|
||||
|
||||
The following table lists for each supported model the port number
|
||||
corresponding to each HDMI output and input.

Amlogic Meson Display Controller
|
||||
================================
|
||||
|
||||
The Amlogic Meson Display controller is composed of several components
|
||||
that are going to be documented below:
|
||||
|
||||
DMC|---------------VPU (Video Processing Unit)----------------|------HHI------|
|
||||
| vd1 _______ _____________ _________________ | |
|
||||
D |-------| |----| | | | | HDMI PLL |
|

|
||||
R |-------| |----| Processing | | | | |
|
||||
| osd2 | | | |---| Enci ----------|----|-----VDAC------|
|

A | osd1 | | | Blenders | | Encl ----------|----|---------------|
|
||||
M |-------|______|----|____________| |________________| | |
|
||||
___|__________________________________________________________|_______________|
|
||||
|
||||
|
||||
VIU: Video Input Unit
|
||||
---------------------
|
||||
|
||||
The Video Input Unit is in charge of the pixel scanout from the DDR memory.
|
||||
It fetches the frames addresses, stride and parameters from the "Canvas" memory.
|
||||
This part is also in charge of the CSC (Colorspace Conversion).
|
||||
It can handle 2 OSD Planes and 2 Video Planes.
|
||||
|
||||
VPP: Video Post Processing
|
||||
--------------------------
|
||||
|
||||
The Video Post Processing is in charge of the scaling and blending of the
|
||||
various planes into a single pixel stream.
|
||||
There is a special "pre-blending" used by the video planes with a dedicated
|
||||
scaler and a "post-blending" to merge with the OSD Planes.
|
||||
The OSD planes also have a dedicated scaler for one of the OSD.
|
||||
|
||||
VENC: Video Encoders
|
||||
--------------------
|
||||
|
||||
The VENC is composed of the multiple pixel encoders :
|
||||
- ENCI : Interlace Video encoder for CVBS and Interlace HDMI
|
||||
- ENCP : Progressive Video Encoder for HDMI
|
||||
- ENCL : LCD LVDS Encoder
|
||||
The VENC Unit gets a Pixel Clocks (VCLK) from a dedicated HDMI PLL and clock
|
||||
tree and provides the scanout clock to the VPP and VIU.
|
||||
The ENCI is connected to a single VDAC for Composite Output.
|
||||
The ENCI and ENCP are connected to an on-chip HDMI Transceiver.
|
||||
|
||||
Device Tree Bindings:
|
||||
---------------------
|
||||
|
||||
VPU: Video Processing Unit
|
||||
--------------------------
|
||||
|
||||
Required properties:
|
||||
- compatible: value should be different for each SoC family as :
|
||||
- GXBB (S905) : "amlogic,meson-gxbb-vpu"
|
||||
- GXL (S905X, S905D) : "amlogic,meson-gxl-vpu"
|
||||
- GXM (S912) : "amlogic,meson-gxm-vpu"
|
||||
followed by the common "amlogic,meson-gx-vpu"
|
||||
- G12A (S905X2, S905Y2, S905D2) : "amlogic,meson-g12a-vpu"
|
||||
- reg: base address and size of he following memory-mapped regions :
|
||||
- vpu
|
||||
- hhi
|
||||
- reg-names: should contain the names of the previous memory regions
|
||||
- interrupts: should contain the VENC Vsync interrupt number
|
||||
- amlogic,canvas: phandle to canvas provider node as described in the file
|
||||
../soc/amlogic/amlogic,canvas.txt
|
||||
|
||||
Optional properties:
|
||||
- power-domains: Optional phandle to associated power domain as described in
|
||||
the file ../power/power_domain.txt
|
||||
|
||||
Required nodes:
|
||||
|
||||
The connections to the VPU output video ports are modeled using the OF graph
|
||||
bindings specified in Documentation/devicetree/bindings/graph.txt.
|
||||
|
||||
The following table lists for each supported model the port number
|
||||
corresponding to each VPU output.

Common Properties for Display Panel
|
||||
===================================
|
||||
|
||||
This document defines device tree properties common to several classes of
|
||||
display panels. It doesn't constitue a device tree binding specification by
|
||||
itself but is meant to be referenced by device tree bindings.
|
||||
|
||||
When referenced from panel device tree bindings the properties defined in this
|
||||
document are defined as follows. The panel device tree bindings are
|
||||
responsible for defining whether each property is required or optional.
|
||||
|
||||
|
||||
Descriptive Properties
|
||||
----------------------
|
||||
|
||||
- width-mm,
|
||||
- height-mm: The width-mm and height-mm specify the width and height of the
|
||||
physical area where images are displayed. These properties are expressed in
|
||||
millimeters and rounded to the closest unit.
|
||||
|
||||
- label: The label property specifies a symbolic name for the panel as a
|
||||
string suitable for use by humans. It typically contains a name inscribed on
|
||||
the system (e.g. as an affixed label) or specified in the system's
|
||||
documentation (e.g. in the user's manual).
|
||||
|
||||
If no such name exists, and unless the property is mandatory according to
|
||||
device tree bindings, it shall rather be omitted than constructed of
|
||||
non-descriptive information. For instance an LCD panel in a system that
|
||||
contains a single panel shall not be labelled "LCD" if that name is not
|
||||
inscribed on the system or used in a descriptive fashion in system
|
||||
documentation.
|
||||
|
||||
|
||||
Display Timings
|
||||
---------------
|
||||
|
||||
- panel-timing: Most display panels are restricted to a single resolution and
|
||||
require specific display timings. The panel-timing subnode expresses those
|
||||
timings as specified in the timing subnode section of the display timing
|
||||
bindings defined in
|
||||
Documentation/devicetree/bindings/display/panel/display-timing.txt.
|
||||
|
||||
|
||||
Connectivity
|
||||
------------
|
||||
|
||||
- ports: Panels receive video data through one or multiple connections. While
|
||||
the nature of those connections is specific to the panel type, the
|
||||
connectivity is expressed in a standard fashion using ports as specified in
|
||||
the device graph bindings defined in
|
||||
Documentation/devicetree/bindings/graph.txt.
|
||||
|
||||
- ddc-i2c-bus: Some panels expose EDID information through an I2C-compatible
|
||||
bus such as DDC2 or E-DDC. For such panels the ddc-i2c-bus contains a
|
||||
phandle to the system I2C controller connected to that bus.
|
||||
|
||||
|
||||
Control I/Os
|
||||
------------
|
||||
|
||||
Many display panels can be controlled through pins driven by GPIOs. The nature
|
||||
and timing of those control signals are device-specific and left for panel
|
||||
device tree bindings to specify. The following GPIO specifiers can however be
|
||||
used for panels that implement compatible control signals.
|
||||
|
||||
- enable-gpios: Specifier for a GPIO connected to the panel enable control
|
||||
signal. The enable signal is active high and enables operation of the panel.
|
||||
This property can also be used for panels implementing an active low power
|
||||
down signal, which is a negated version of the enable signal. Active low
|
||||
enable signals (or active high power down signals) can be supported by
|
||||
inverting the GPIO specifier polarity flag.
|
||||
|
||||
Note that the enable signal control panel operation only and must not be
|
||||
confused with a backlight enable signal.
|
||||
|
||||
- reset-gpios: Specifier for a GPIO coonnected to the panel reset control
|
||||
signal. The reset signal is active low and resets the panel internal logic
|
||||
while active. Active high reset signals can be supported by inverting the
|
||||
GPIO specifier polarity flag.
|
||||
|
||||
Power
|
||||
-----
|
||||
|
||||
- power-supply: display panels require power to be supplied. While several
|
||||
panels need more than one power supply with panel-specific constraints
|
||||
governing the order and timings of the power supplies, in many cases a single
|
||||
power supply is sufficient, either because the panel has a single power rail,
|
||||
or because all its power rails can be driven by the same supply. In that case
|
||||
the power-supply property specifies the supply powering the panel as a phandle
|
||||
to a regulator.
|
||||
|
||||
Backlight
|
||||
---------
|
||||
|
||||
Most display panels include a backlight. Some of them also include a backlight
|
||||
controller exposed through a control bus such as I2C or DSI. Others expose
|
||||
backlight control through GPIO, PWM or other signals connected to an external
|
||||
backlight controller.
|
||||
|
||||
- backlight: For panels whose backlight is controlled by an external backlight
|
||||
controller, this property contains a phandle that references the controller.

TPO TPG110 Panel
|
||||
================
|
||||
|
||||
This panel driver is a component that acts as an intermediary
|
||||
between an RGB output and a variety of panels. The panel
|
||||
driver is strapped up in electronics to the desired resolution
|
||||
and other properties, and has a control interface over 3WIRE
|
||||
SPI. By talking to the TPG110 over SPI, the strapped properties
|
||||
can be discovered and the hardware is therefore mostly
|
||||
self-describing.
|
||||
|
||||
+--------+
|
||||
SPI -> | TPO | -> physical display
|
||||
RGB -> | TPG110 |
|
||||
+--------+
|
||||
|
||||
If some electrical strap or alternate resolution is desired,
|
||||
this can be set up by taking software control of the display
|
||||
over the SPI interface. The interface can also adjust
|
||||
for properties of the display such as gamma correction and
|
||||
certain electrical driving levels.
|
||||
|
||||
The TPG110 does not know the physical dimensions of the panel
|
||||
connected, so this needs to be specified in the device tree.
|
||||
|
||||
It requires a GPIO line for control of its reset line.
|
||||
|
||||
The serial protocol has line names that resemble I2C but the
|
||||
protocol is not I2C but 3WIRE SPI.
|
||||
|
||||
Required properties:
|
||||
- compatible : one of:
|
||||
"ste,nomadik-nhk15-display", "tpo,tpg110"
|
||||
"tpo,tpg110"
|
||||
- grestb-gpios : panel reset GPIO
|
||||
- width-mm : see display/panel/panel-common.txt
|
||||
- height-mm : see display/panel/panel-common.txt
|
||||
|
||||
The device needs to be a child of an SPI bus, see
|
||||
spi/spi-bus.txt. The SPI child must set the following
|
||||
properties:
|
||||
- spi-3wire
|
||||
- spi-max-frequency = <3000000>;
|
||||
as these are characteristics of this device.
|
||||
|
||||
The device node can contain one 'port' child node with one child
|
||||
'endpoint' node, according to the bindings defined in
|
||||
media/video-interfaces.txt. This node should describe panel's video bus.
|
||||
|
||||
Example
|
||||
-------
|
||||
|
||||
panel: display@0 {
|
||||
compatible = "tpo,tpg110";
|
||||
reg = <0>;
|
||||
spi-3wire;
|
||||
/* 320 ns min period ~= 3 MHz */
|
||||
spi-max-frequency = <3000000>;
|
||||
/* Width and height from data sheet */
|
||||
width-mm = <116>;
|
||||
height-mm = <87>;
|
||||
grestb-gpios = <&foo_gpio 5 GPIO_ACTIVE_LOW>;
|
||||
backlight = <&bl>;
|
||||
|
||||
port {
|
||||
nomadik_clcd_panel: endpoint {
|
||||
remote-endpoint = <&foo>;

Overview and Driver Interface
|

-----------------------------
|

Overview and Lifetime Rules
|
||||
---------------------------
|
||||
|
||||
Similar to GEM global names, PRIME file descriptors are also used to
|
||||
share buffer objects across processes. They offer additional security:
|
||||
as file descriptors must be explicitly sent over UNIX domain sockets to
|
||||
be shared between applications, they can't be guessed like the globally
|
||||
unique GEM names.
|
||||
|
||||
Drivers that support the PRIME API must set the DRIVER_PRIME bit in the
|
||||
struct :c:type:`struct drm_driver <drm_driver>`
|
||||
driver_features field, and implement the prime_handle_to_fd and
|
||||
prime_fd_to_handle operations.
|
||||
|
||||
int (\*prime_handle_to_fd)(struct drm_device \*dev, struct drm_file
|
||||
\*file_priv, uint32_t handle, uint32_t flags, int \*prime_fd); int
|
||||
(\*prime_fd_to_handle)(struct drm_device \*dev, struct drm_file
|
||||
\*file_priv, int prime_fd, uint32_t \*handle); Those two operations
|
||||
convert a handle to a PRIME file descriptor and vice versa. Drivers must
|
||||
use the kernel dma-buf buffer sharing framework to manage the PRIME file
|
||||
descriptors. Similar to the mode setting API PRIME is agnostic to the
|
||||
underlying buffer object manager, as long as handles are 32bit unsigned
|
||||
integers.
|
||||
|
||||
While non-GEM drivers must implement the operations themselves, GEM
|
||||
drivers must use the :c:func:`drm_gem_prime_handle_to_fd()` and
|
||||
:c:func:`drm_gem_prime_fd_to_handle()` helper functions. Those
|
||||
helpers rely on the driver gem_prime_export and gem_prime_import
|
||||
operations to create a dma-buf instance from a GEM object (dma-buf
|
||||
exporter role) and to create a GEM object from a dma-buf instance
|
||||
(dma-buf importer role).
|
||||
|
||||
struct dma_buf \* (\*gem_prime_export)(struct drm_device \*dev,

Documentation Requirements for kAPI

All kernel APIs exported to other modules must be documented, including their

concepts. Documentation should be put into the code itself as kerneldoc comments

Do not blindly document everything, but document only what's relevant for driver

authors: Internal functions of drm.ko and definitely static functions should not

is warranted. You may use kerneldoc syntax in the comment, but it shall not

anything entirely private with ``/* private: */`` comments as per the

this (together with the drm_minor->drm_device move) would allow us to remove

- Drop the return code and error checking from all debugfs functions. Greg KH is

Backlight Refactoring
|
||||
---------------------
|
||||
|
||||
Backlight drivers have a triple enable/disable state, which is a bit overkill.
|
||||
Plan to fix this:
|
||||
|
||||
1. Roll out backlight_enable() and backlight_disable() helpers everywhere. This
|
||||
has started already.
|
||||
2. In all, only look at one of the three status bits set by the above helpers.
|
||||
3. Remove the other two status bits.

Driver Specific
|

===============
|
||||
|
||||
tinydrm
|
||||
-------
|
||||
|
||||
Tinydrm is the helper driver for really simple fb drivers. The goal is to make
|
||||
those drivers as simple as possible, so lots of room for refactoring:
|
||||
|
||||
- backlight helpers, probably best to put them into a new drm_backlight.c.
|
||||
This is because drivers/video is de-facto unmaintained. We could also
|
||||
move drivers/video/backlight to drivers/gpu/backlight and take it all
|
||||
over within drm-misc, but that's more work. Backlight helpers require a fair
|
||||
bit of reworking and refactoring. A simple example is the enabling of a backlight.
|
||||
Tinydrm has helpers for this. It would be good if other drivers can also use the
|
||||
helper. However, there are various cases we need to consider i.e different
|
||||
drivers seem to have different ways of enabling/disabling a backlight.
|
||||
We also need to consider the backlight drivers (like gpio_backlight). The situation
|
||||
is further complicated by the fact that the backlight is tied to fbdev
|
||||
via fb_notifier_callback() which has complicated logic. For further details, refer
|
||||
to the following discussion thread:
|
||||
https://groups.google.com/forum/#!topic/outreachy-kernel/8rBe30lwtdA
|
||||
|
||||
- spi helpers, probably best put into spi core/helper code. Thierry said
|
||||
the spi maintainer is fast&reactive, so shouldn't be a big issue.
|
||||
|
||||
- extract the mipi-dbi helper (well, the non-tinydrm specific parts at
|
||||
least) into a separate helper, like we have for mipi-dsi already. Or follow
|
||||
one of the ideas for having a shared dsi/dbi helper, abstracting away the
|
||||
transport details more.
