[PATCH v4 00/24] pwm: add support for atomic update

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 v3:
- rebased on pwm/for-next after pulling 4.4-rc1
- replace direct access to pwm fields by pwm_get/set_xxx() helpers, thus
fixing some build errors
- split changes to allow each maintainer to review/ack or take the
modification through its subsystem

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 (23):
pwm: rcar: make use of pwm_is_enabled()
pwm: use pwm_get_xxx() helpers where appropriate
clk: pwm: use pwm_get_xxx() helpers where appropriate
hwmon: pwm-fan: use pwm_get_xxx() helpers where appropriate
misc: max77693-haptic: use pwm_get_xxx() helpers where appropriate
pwm: introduce default period and polarity concepts
pwm: use pwm_get/set_default_xxx() helpers where appropriate
leds: pwm: use pwm_get/set_default_xxx() helpers where appropriate
regulator: pwm: use pwm_get/set_default_xxx() helpers where
appropriate
backlight: pwm: use pwm_get/set_default_xxx() helpers where
appropriate
fbdev: use pwm_get/set_default_xxx() helpers where appropriate
misc: max77693: use pwm_get/set_default_xxx() helpers where
appropriate
hwmon: pwm-fan: use pwm_get/set_default_xxx() helpers where
appropriate
clk: pwm: use pwm_get/set_default_xxx() helpers where appropriate
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: properly initialize the ->state field

Heiko Stübner (1):
pwm: add information about polarity, duty cycle and period to debugfs
