[PATCH 0/5] r8a7742: Enable support for CMT, PWM and TPU

[Lad Prabhakar]

Hi All,

This patch series adds support for PWM and TPU to r8a7742 SoC dtsi
and enables CMT0 node for r8a7742-iwg21d-q7 board.

Cheers,
Prabhakar

[PATCH 4/5] dt-bindings: pwm: renesas,tpu-pwm: Document r8a7742 support

[Lad Prabhakar]

Document r8a7742 specific compatible strings. No driver change is
needed as the fallback compatible string "renesas,tpu" activates the
right code in the driver.

The typical dts has:

	compatible = "renesas,pwm-r8a7742", "renesas,pwm-rcar";

so there is no need for a driver adaption.
