"There are a bunch of changes all over in the usual places.
Highlights:
- habanalabs moves from misc to accel
- first accel driver for Intel VPU (Versatile Processing Unit)
inference engine
- dropped all the ancient legacy DRI1 drivers. I think it's been at
least 10 years since anyone has heard about these.

with inference accelerators)

Cadence DSI bridge
|
||||
==================
|
||||
|
||||
The Cadence DSI bridge is a DPI to DSI bridge supporting up to 4 DSI lanes.
|
||||
|
||||
Required properties:
|
||||
- compatible: should be set to "cdns,dsi".
|
||||
- reg: physical base address and length of the controller's registers.
|
||||
- interrupts: interrupt line connected to the DSI bridge.
|
||||
- clocks: DSI bridge clocks.
|
||||
- clock-names: must contain "dsi_p_clk" and "dsi_sys_clk".
|
||||
- phys: phandle link to the MIPI D-PHY controller.
|
||||
- phy-names: must contain "dphy".
|
||||
- #address-cells: must be set to 1.
|
||||
- #size-cells: must be set to 0.
|
||||
|
||||
Optional properties:
|
||||
- resets: DSI reset lines.
|
||||
- reset-names: can contain "dsi_p_rst".
|
||||
|
||||
Required subnodes:
|
||||
- ports: Ports as described in Documentation/devicetree/bindings/graph.txt.
|
||||
2 ports are available:
|
||||
* port 0: this port is only needed if some of your DSI devices are
|
||||
controlled through an external bus like I2C or SPI. Can have at
|
||||
most 4 endpoints. The endpoint number is directly encoding the
|
||||
DSI virtual channel used by this device.
|
||||
* port 1: represents the DPI input.
|
||||
Other ports will be added later to support the new kind of inputs.
|
||||
|
||||
- one subnode per DSI device connected on the DSI bus. Each DSI device should
|
||||
contain a reg property encoding its virtual channel.
|
||||
|
||||
Example:
|
||||
dsi0: dsi@fd0c0000 {

Qualcomm adreno/snapdragon MDP5 display controller
|
||||
|
||||
Description:
|
||||
|
||||
This is the bindings documentation for the MDP5 display
|
||||
controller found in SoCs like MSM8974, APQ8084, MSM8916, MSM8994 and MSM8996.
|
||||
|
||||
MDP5:
|
||||
Required properties:
|
||||
- compatible:
|
||||
* "qcom,mdp5" - MDP5
|
||||
- reg: Physical base address and length of the controller's registers.
|
||||
- reg-names: The names of register regions. The following regions are required:
|
||||
* "mdp_phys"
|
||||
- interrupts: Interrupt line from MDP5 to MDSS interrupt controller.
|
||||
- clocks: device clocks. See ../clocks/clock-bindings.txt for details.
|
||||
- clock-names: the following clocks are required.
|
||||
- * "bus"
|
||||
- * "iface"
|
||||
- * "core"
|
||||
- * "vsync"
|
||||
- ports: contains the list of output ports from MDP. These connect to interfaces
|
||||
that are external to the MDP hardware, such as HDMI, DSI, EDP etc (LVDS is a
|
||||
special case since it is a part of the MDP block itself).
|
||||
|
||||
Each output port contains an endpoint that describes how it is connected to an
|
||||
external interface. These are described by the standard properties documented
|
||||
here:
|
||||
Documentation/devicetree/bindings/graph.txt
|
||||
Documentation/devicetree/bindings/media/video-interfaces.txt
|
||||
|
||||
The availability of output ports can vary across SoC revisions:
|
||||
|
||||
For MSM8974 and APQ8084:
|
||||
Port 0 -> MDP_INTF0 (eDP)
|
||||
Port 1 -> MDP_INTF1 (DSI1)
|
||||
Port 2 -> MDP_INTF2 (DSI2)
|
||||
Port 3 -> MDP_INTF3 (HDMI)
|
||||
|
||||
For MSM8916:
|
||||
Port 0 -> MDP_INTF1 (DSI1)
|
||||
|
||||
For MSM8994 and MSM8996:
|
||||
Port 0 -> MDP_INTF1 (DSI1)
|
||||
Port 1 -> MDP_INTF2 (DSI2)
|
||||
Port 2 -> MDP_INTF3 (HDMI)
|
||||
|
||||
Optional properties:
|
||||
- clock-names: the following clocks are optional:
|
||||
* "lut"
|
||||
* "tbu"
|
||||
* "tbu_rt"

There's a bunch of issues with it:

- The drm_info_list ->show() function doesn't even bother to cast to the drm

- Convert drivers to support the drm_debugfs_add_files() function instead of

the drm_debugfs_create_files() function.

- Improve late-register debugfs by rolling out the same debugfs pre-register

infrastructure for connector and crtc too. That way, the drivers won't need to

split their setup code into init and register anymore.

- We probably want to have some support for debugfs files on crtc/connectors and

maybe other kms objects directly in core. There's even drm_print support in

the funcs for these objects to dump kms state, so it's all there. And then the

->show() functions should obviously give you a pointer to the right object.

- The drm_info_list stuff is centered on drm_minor instead of drm_device. For

anything we want to print drm_device (or maybe drm_file) is the right thing.

- The drm_driver->debugfs_init hooks we have is just an artifact of the old

===========

The VC4 Driver uses KUnit to perform driver-specific unit and

||||
integration tests.

These tests are using a mock driver and can be ran using the
|
||||
command below, on either arm or arm64 architectures,
