Add support for the 4 PWM channels provided by the 16-bit Timer Pulse Unit on R-Car H2, by adding a device node describing the TPU. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> --- Tested 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.
