[PATCH 0/6] Add PWM and TPU support to r8a7743

[Fabrizio Castro]

Dear All,

this series includes all that is required to add PWM and TPU SoC specific
support for the r8a7743.

Thanks,

[PATCH 2/6] dt-bindings: pwm: rcar: Document r8a774[35] PWM bindings

[Fabrizio Castro]

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.

Dear All,

the reason for replacing the example with one of a different SoC is that
the new example refers to recent code from a real use case. I hope that's ok.

Thanks,
Fabrizio

Document r8a774[35] specific compatible strings. No driver change is
needed as the fallback compatible string "renesas,tpu" activates the
right code in the driver.
