Thanks, Thierry
This series fixes minor issues in config callback and allows for on the fly updates for pwm period and duty cycle. This is mainly intended to allow pwm omap dmtimer to be used for generating a 1PPS signal that can be syncronized to PTP clock in CPTS module available in AM335x and AM57xx SoCs. Series depends on the following series: - https://patchwork.kernel.org/patch/11379875/ - https://patchwork.kernel.org/project/linux-omap/list/?series=251691 Full dependencies can be seen here: https://github.com/lokeshvutla/linux/tree/devel/pwm-dynamic-period-updates-v3 Changes since v2: - Restored the existing behavior on pwm stop. PWM stops immediately when .stop is called as timer counter stops immediately. If just the autoreload is disabled as in v2, there is a possibility that pwm is never stopped. - Added the above limitation in the driver description - Rebased on top of v5.6-rc5 Changes since v1: - Updated commit description in PATCH 1 - Added a brief about PWM generation using OMAP DM timer. - Updated the pwm stop callback to allow for completing the current pwm cycle. - Added the limitaitons of hardware. - Used hw status instead of relying on pwm framework for state update.
