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!
