* pwm: rcar: Fix late Runtime PM enablementGeert Uytterhoeven2020-05-02
| | | | | | | | | | | | | | | | [ Upstream commit 1451a3eed24b5fd6a604683f0b6995e0e7e16c79 ] Runtime PM should be enabled before calling pwmchip_add(), as PWM users can appear immediately after the PWM chip has been added. Likewise, Runtime PM should be disabled after the removal of the PWM chip.

* pwm: Add support for R-Car PWM TimerYoshihiro Shimoda2015-10-06
This patch adds support for R-Car SoCs PWM Timer. The PWM timer of R-Car H2 has 7 channels. So, we can use the channels if we describe device tree nodes.
