This patch adds compatible strings specific to r8a774[35], no driver change is needed as the fallback compatible string will activate the right code. Also, this patch replaces the example with a DT snippet used for adding PWM0 support to an r8a7743 based platform as the r8a7743 is now the first platform fully compatible with this driver and its PWM DT nodes refer to up-to-date code.

* Renesas R-Car PWM Timer Controller
|
|
|
|
Required Properties:
|
|
- compatible: should be "renesas,pwm-rcar" and one of the following.
|
|
- "renesas,pwm-r8a7743": for RZ/G1M
|
|
- "renesas,pwm-r8a7745": for RZ/G1E
|
|
- "renesas,pwm-r8a7778": for R-Car M1A
|
|
- "renesas,pwm-r8a7779": for R-Car H1
|
|
- "renesas,pwm-r8a7790": for R-Car H2
|
|
- "renesas,pwm-r8a7791": for R-Car M2-W
|
|
- "renesas,pwm-r8a7794": for R-Car E2
|
|
- "renesas,pwm-r8a7795": for R-Car H3
|
|
- "renesas,pwm-r8a7796": for R-Car M3-W
|
|
- "renesas,pwm-r8a77995": for R-Car D3
|
|
- reg: base address and length of the registers block for the PWM.
|
|
- #pwm-cells: should be 2. See pwm.txt in this directory for a description of
|
|
the cells format.
|
|
- clocks: clock phandle and specifier pair.
|
|
- pinctrl-0: phandle, referring to a default pin configuration node.
|
|
- pinctrl-names: Set to "default".
|
|
|

Example: R8A7743 (RZ/G1M) PWM Timer node
|
|
|

resets = <&cpg 523>;
|
|
#pwm-cells = <2>;
|
|
pinctrl-0 = <&pwm0_pins>;
