Subject: dt-bindings: pwm: renesas: tpu: Fix "compatible" prop description
Git-commit: 01e194bbd64a7c65af428561fa97653be8b74564
Patch-mainline: v4.20-rc1
References: git-fixes
The "compatible" property description contradicts even the example given:
it only says that there must be a single value while the example has the
fallback value too -- which makes much more sense. Moreover, the generic
property value is misdocumented as being R-Car (and RZ/G1) specific...

Required Properties:
- - compatible: should be one of the following.
+ - compatible: must contain one or more of the following:
- "renesas,tpu-r8a73a4": for R8A77A4 (R-Mobile APE6) compatible PWM controller.
- "renesas,tpu-r8a7740": for R8A7740 (R-Mobile A1) compatible PWM controller.
- "renesas,tpu-r8a7790": for R8A7790 (R-Car H2) compatible PWM controller.
- "renesas,tpu-sh7372": for SH7372 (SH-Mobile AP4) compatible PWM controller.
- - "renesas,tpu": for generic R-Car TPU PWM controller.
+ - "renesas,tpu": for the generic TPU PWM controller; this is a fallback for
+ the entries listed above.
- reg: Base address and length of each memory resource used by the PWM
controller hardware module.
