Add support for the 7 PWM channels provided by PWM Timers on R-Car H2, by adding device nodes describing the PWM Timers. Signed-off-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx> --- PWM1(b) and PWM3-6 have bested with PWM sysfs and a logic analyzer on the Lager development board using DT overlays available from [1]. To be queued in renesas-devel-for-v6.4.
