* Clock bindings for Freescale i.MX7ULP
|
||||
|
||||
i.MX7ULP Clock functions are under joint control of the System
|
||||
Clock Generation (SCG) modules, Peripheral Clock Control (PCC)
|
||||
modules, and Core Mode Controller (CMC)1 blocks
|
||||
|
||||
The clocking scheme provides clear separation between M4 domain
|
||||
and A7 domain. Except for a few clock sources shared between two
|
||||
domains, such as the System Oscillator clock, the Slow IRC (SIRC),
|
||||
and and the Fast IRC clock (FIRCLK), clock sources and clock
|
||||
management are separated and contained within each domain.
|
||||
|
||||
M4 clock management consists of SCG0, PCC0, PCC1, and CMC0 modules.
|
||||
A7 clock management consists of SCG1, PCC2, PCC3, and CMC1 modules.
|
||||
|
||||
Note: this binding doc is only for A7 clock domain.
|
||||
|
||||
System Clock Generation (SCG) modules:
|
||||
---------------------------------------------------------------------
|
||||
The System Clock Generation (SCG) is responsible for clock generation
|
||||
and distribution across this device. Functions performed by the SCG
|
||||
include: clock reference selection, generation of clock used to derive
|
||||
processor, system, peripheral bus and external memory interface clocks,
|
||||
source selection for peripheral clocks and control of power saving
|
||||
clock gating mode.
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible: Should be "fsl,imx7ulp-scg1".
|
||||
- reg : Should contain registers location and length.
|
||||
- #clock-cells: Should be <1>.
|
||||
- clocks: Should contain the fixed input clocks.
|
||||
- clock-names: Should contain the following clock names:
|
||||
"rosc", "sosc", "sirc", "firc", "upll", "mpll".
|
||||
|
||||
Peripheral Clock Control (PCC) modules:
|
||||
---------------------------------------------------------------------
|
||||
The Peripheral Clock Control (PCC) is responsible for clock selection,
|
||||
optional division and clock gating mode for peripherals in their
|
||||
respected power domain
|
||||
|
||||
Required properties:
|
||||
- compatible: Should be one of:
|
||||
"fsl,imx7ulp-pcc2",
|
||||
"fsl,imx7ulp-pcc3".
|
||||
- reg : Should contain registers location and length.
|
||||
- #clock-cells: Should be <1>.
|
||||
- clocks: Should contain the fixed input clocks.
|
||||
- clock-names: Should contain the following clock names:
|
||||
"nic1_bus_clk", "nic1_clk", "ddr_clk", "apll_pfd2",
|
||||
"apll_pfd1", "apll_pfd0", "upll", "sosc_bus_clk",
|
||||
"mpll", "firc_bus_clk", "rosc", "spll_bus_clk";
|
||||
|
||||
The clock consumer should specify the desired clock by having the clock
|
||||
ID in its "clocks" phandle cell.
|
||||
See include/dt-bindings/clock/imx7ulp-clock.h
|
||||
for the full list of i.MX7ULP clock IDs of each module.

* Marvell PXA GPIO controller
|
||||
|
||||
Required properties:
|
||||
- compatible : Should be "intel,pxa25x-gpio", "intel,pxa26x-gpio",
|
||||
"intel,pxa27x-gpio", "intel,pxa3xx-gpio",
|
||||
"marvell,pxa93x-gpio", "marvell,mmp-gpio",
|
||||
"marvell,mmp2-gpio" or marvell,pxa1928-gpio.
|
||||
- reg : Address and length of the register set for the device
|
||||
- interrupts : Should be the port interrupt shared by all gpio pins.
|
||||
There're three gpio interrupts in arch-pxa, and they're gpio0,
|
||||
gpio1 and gpio_mux. There're only one gpio interrupt in arch-mmp,
|
||||
gpio_mux.
|
||||
- interrupt-names : Should be the names of irq resources. Each interrupt
|
||||
uses its own interrupt name, so there should be as many interrupt names
|
||||
as referenced interrupts.
|
||||
- interrupt-controller : Identifies the node as an interrupt controller.
|
||||
- #interrupt-cells: Specifies the number of cells needed to encode an
|
||||
interrupt source.
|
||||
- gpio-controller : Marks the device node as a gpio controller.
|
||||
- #gpio-cells : Should be two. The first cell is the pin number and
|
||||
the second cell is used to specify flags. See gpio.txt for possible
|
||||
values.
|
||||
|
||||
Example for a MMP platform:
|
||||
|
||||
gpio: gpio@d4019000 {
|
||||
compatible = "marvell,mmp-gpio";
|
||||
reg = <0xd4019000 0x1000>;
|
||||
interrupts = <49>;
|
||||
interrupt-names = "gpio_mux";
|
||||
gpio-controller;
|
||||
#gpio-cells = <2>;
|
||||
interrupt-controller;
|
||||
#interrupt-cells = <1>;
|
||||
};
|
||||
|
||||
Example for a PXA3xx platform:
|
||||
|
||||
gpio: gpio@40e00000 {
|
||||
compatible = "intel,pxa3xx-gpio";
|
||||
reg = <0x40e00000 0x10000>;
|
||||
interrupt-names = "gpio0", "gpio1", "gpio_mux";
|
||||
interrupts = <8 9 10>;
|
||||
gpio-controller;
|
||||
#gpio-cells = <0x2>;
|
||||
interrupt-controller;
|
||||
#interrupt-cells = <0x2>;

||||

A simple common binding for matrix-connected key boards. Currently targeted at
|
||||
defining the keys in the scope of linux key codes since that is a stable and
|
||||
standardized interface at this time.
|
||||
|
||||
Required properties:
|
||||
- linux,keymap: an array of packed 1-cell entries containing the equivalent
|
||||
of row, column and linux key-code. The 32-bit big endian cell is packed
|
||||
as:
|
||||
row << 24 | column << 16 | key-code
|
||||
|
||||
Optional properties:
|
||||
Properties for the number of rows and columns are optional because some
|
||||
drivers will use fixed values for these.
|
||||
- keypad,num-rows: Number of row lines connected to the keypad controller.
|
||||
- keypad,num-columns: Number of column lines connected to the keypad
|
||||
controller.
|
||||
|
||||
Some users of this binding might choose to specify secondary keymaps for
|
||||
cases where there is a modifier key such as a Fn key. Proposed names
|
||||
for said properties are "linux,fn-keymap" or with another descriptive
|
||||
word for the modifier other from "Fn".

DT bindings for the Renesas RZ/A1 Interrupt Controller
|
||||
|
||||
The RZ/A1 Interrupt Controller is a front-end for the GIC found on Renesas
|
||||
RZ/A1 and RZ/A2 SoCs:
|
||||
- IRQ sense select for 8 external interrupts, 1:1-mapped to 8 GIC SPI
|
||||
interrupts,
|
||||
- NMI edge select.
|
||||
|
||||
Required properties:
|
||||
- compatible: Must be "renesas,<soctype>-irqc", and "renesas,rza1-irqc" as
|
||||
fallback.
|
||||
Examples with soctypes are:
|
||||
- "renesas,r7s72100-irqc" (RZ/A1H)
|
||||
- "renesas,r7s9210-irqc" (RZ/A2M)
|
||||
- #interrupt-cells: Must be 2 (an interrupt index and flags, as defined
|
||||
in interrupts.txt in this directory)
|
||||
- #address-cells: Must be zero
|
||||
- interrupt-controller: Marks the device as an interrupt controller
|
||||
- reg: Base address and length of the memory resource used by the interrupt
|
||||
controller
|
||||
- interrupt-map: Specifies the mapping from external interrupts to GIC
|
||||
interrupts
|
||||
- interrupt-map-mask: Must be <7 0>

pwm-backlight bindings
|
||||
|
||||
Required properties:
|
||||
- compatible: "pwm-backlight"
|
||||
- pwms: OF device-tree PWM specification (see PWM binding[0])
|
||||
- power-supply: regulator for supply voltage
|
||||
|
||||
Optional properties:
|
||||
- pwm-names: a list of names for the PWM devices specified in the
|
||||
"pwms" property (see PWM binding[0])
|
||||
- enable-gpios: contains a single GPIO specifier for the GPIO which enables
|
||||
and disables the backlight (see GPIO binding[1])
|
||||
- post-pwm-on-delay-ms: Delay in ms between setting an initial (non-zero) PWM
|
||||
and enabling the backlight using GPIO.
|
||||
- pwm-off-delay-ms: Delay in ms between disabling the backlight using GPIO
|
||||
and setting PWM value to 0.
|
||||
- brightness-levels: Array of distinct brightness levels. Typically these
|
||||
are in the range from 0 to 255, but any range starting at
|
||||
0 will do. The actual brightness level (PWM duty cycle)
|
||||
will be interpolated from these values. 0 means a 0% duty
|
||||
cycle (darkest/off), while the last value in the array
|
||||
represents a 100% duty cycle (brightest).
|
||||
- default-brightness-level: The default brightness level (index into the
|
||||
array defined by the "brightness-levels" property).
|
||||
- num-interpolated-steps: Number of interpolated steps between each value
|
||||
of brightness-levels table. This way a high
|
||||
resolution pwm duty cycle can be used without
|
||||
having to list out every possible value in the
|
||||
brightness-level array.

strobing the ACK pin with the ready signal. See the "ready-gpios" property of the

|
||||
This binding describes the Embedded Controller acting as a SPI bus master
|
||||
on a OLPC XO-1.75 laptop computer.
|
||||
|
||||
The embedded controller requires the SPI controller driver to signal
|
||||
readiness to receive a transfer (that is, when TX FIFO contains the
|
||||
response data) by strobing the ACK pin with the ready signal. See the
|
||||
"ready-gpios" property of the SSP binding as documented in:
|
||||
<Documentation/devicetree/bindings/spi/marvell,mmp2-ssp.yaml>.

* Freescale Enhanced Secure Digital Host Controller (eSDHC) for i.MX
|
||||
|
||||
The Enhanced Secure Digital Host Controller on Freescale i.MX family
|
||||
provides an interface for MMC, SD, and SDIO types of memory cards.
|
||||
|
||||
This file documents differences between the core properties described
|
||||
by mmc.txt and the properties used by the sdhci-esdhc-imx driver.
|
||||
|
||||
Required properties:
|
||||
- compatible : Should be "fsl,<chip>-esdhc", the supported chips include
|
||||
"fsl,imx25-esdhc"
|
||||
"fsl,imx35-esdhc"
|
||||
"fsl,imx51-esdhc"
|
||||
"fsl,imx53-esdhc"
|
||||
"fsl,imx6q-usdhc"
|
||||
"fsl,imx6sl-usdhc"
|
||||
"fsl,imx6sx-usdhc"
|
||||
"fsl,imx6ull-usdhc"
|
||||
"fsl,imx7d-usdhc"
|
||||
"fsl,imx7ulp-usdhc"
|
||||
"fsl,imx8mq-usdhc"
|
||||
"fsl,imx8mm-usdhc"
|
||||
"fsl,imx8mn-usdhc"
|
||||
"fsl,imx8mp-usdhc"
|
||||
"fsl,imx8qm-usdhc"
|
||||
"fsl,imx8qxp-usdhc"
|
||||
|
||||
Optional properties:
|
||||
- fsl,wp-controller : Indicate to use controller internal write protection
|
||||
- fsl,delay-line : Specify the number of delay cells for override mode.
|
||||
This is used to set the clock delay for DLL(Delay Line) on override mode
|
||||
to select a proper data sampling window in case the clock quality is not good
|
||||
due to signal path is too long on the board. Please refer to eSDHC/uSDHC
|
||||
chapter, DLL (Delay Line) section in RM for details.
|
||||
- voltage-ranges : Specify the voltage range in case there are software
|
||||
transparent level shifters on the outputs of the controller. Two cells are
|
||||
required, first cell specifies minimum slot voltage (mV), second cell
|
||||
specifies maximum slot voltage (mV). Several ranges could be specified.
|
||||
- fsl,tuning-start-tap: Specify the start dealy cell point when send first CMD19
|
||||
in tuning procedure.
|
||||
- fsl,tuning-step: Specify the increasing delay cell steps in tuning procedure.
|
||||
The uSDHC use one delay cell as default increasing step to do tuning process.
|
||||
This property allows user to change the tuning step to more than one delay
|
||||
cells which is useful for some special boards or cards when the default
|
||||
tuning step can't find the proper delay window within limited tuning retries.
|
||||
- fsl,strobe-dll-delay-target: Specify the strobe dll control slave delay target.
|
||||
This delay target programming host controller loopback read clock, and this
|
||||
property allows user to change the delay target for the strobe input read clock.
|
||||
If not use this property, driver default set the delay target to value 7.
|
||||
Only eMMC HS400 mode need to take care of this property.
|
||||
|
||||
Examples:
|
||||
|
||||
esdhc@70004000 {
|
||||
compatible = "fsl,imx51-esdhc";
|
||||
reg = <0x70004000 0x4000>;

||||
* imx28
|
||||
* imx6q
|
||||
* imx6sx
|
||||
* imx7d
|
||||
- reg : should contain registers location and length for gpmi and bch.
|
||||
- reg-names: Should contain the reg names "gpmi-nand" and "bch"
|
||||
- interrupts : BCH interrupt number.
|
||||
- interrupt-names : Should be "bch".
|
||||
- dmas: DMA specifier, consisting of a phandle to DMA controller node
|
||||
and GPMI DMA channel ID.
|
||||
Refer to dma.txt and fsl-mxs-dma.txt for details.
|
||||
- dma-names: Must be "rx-tx".
|
||||
- clocks : clocks phandle and clock specifier corresponding to each clock
|
||||
specified in clock-names.
|
||||
- clock-names : The "gpmi_io" clock is always required. Which clocks are
|
||||
exactly required depends on chip:
|
||||
* imx23/imx28 : "gpmi_io"
|
||||
* imx6q/sx : "gpmi_io", "gpmi_apb", "gpmi_bch", "gpmi_bch_apb", "per1_bch"

|
||||
strength required. The required ECC strength is
|
||||
automatically discoverable for some flash
|
||||
(e.g., according to the ONFI standard).
|
||||
However, note that if this strength is not
|
||||
discoverable or this property is not enabled,
|
||||
the software may chooses an implementation-defined
|
||||
ECC scheme.
