[PATCH 0/2] ARM: dts: r8a7779: Add PWM support

[PATCH 0/2] ARM: dts: r8a7779: Add PWM support

[Geert Uytterhoeven]

	Hi all,

This patch series adds support for the seven PWM Timers on the Renesas
R-Car H1 SoC.

For proper operation, this depends on [1].  PWM0 (b/d), PWM2, and PWM5
have been tested with PWM sysfs and a logic analyzer on the Marzen
development board using DT overlays available from [2].

I plan to queue this series in renesas-devel-for-v6.4.

Thanks for your comments!
