Hello,
This series adds support for atomic PWM update, or IOW, the capability to update all the parameters of a PWM device (enabled/disabled, period, duty and polarity) in one go.
Best Regards,
Boris
Changes since v2: - rebased on top of 4.3-rc2 - reintroduced pwm-regulator patches
Changes since v1: - dropped applied patches - squashed Heiko's fixes into the rockchip driver changes - made a few cosmetic changes - added kerneldoc comments - added Heiko's patch to display more information in debugfs - dropped pwm-regulator patches (should be submitted separately)
Boris Brezillon (11): pwm: introduce default period and polarity concepts pwm: define a new pwm_state struct pwm: move the enabled/disabled info to pwm_state struct backlight: pwm_bl: remove useless call to pwm_set_period pwm: declare a default PWM state pwm: add the PWM initial state retrieval infra pwm: add the core infrastructure to allow atomic update pwm: rockchip: add initial state retrieval pwm: rockchip: add support for atomic update regulator: pwm: implement ->enable(), ->disable() and ->is_enabled methods regulator: pwm: properly initialize the ->state field
Heiko Stübner (1): pwm: add information about polarity, duty cycle and period to debugfs
