On a Freescale i.MX53 based board we ran into "BUG: scheduling while atomic" because input_inject_event locks interrupts, but imx_pwm_config_v2 sleeps. Tested on Freescale i.MX53 SoC with 4.6.0.

This is influenced by the DRM atomic API that was introduced a while back, though it is obviously a lot simpler. The fundamental idea remains the same, though: drivers provide a single callback to implement the atomic configuration of a PWM channel. As a side-effect the PWM subsystem gains the ability for initial state retrieval, so that the logical state mirrors that of the hardware. Many use-cases don't care about this, but for others it is essential. These new features require changes in all users, which these patches take care of. The core is transitioned to use the atomic callback if available and provides a fallback mechanism for other drivers. Changes to transition users and drivers to the atomic API are postponed to v4.8" * tag 'pwm/for-4.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm: (30 commits) pwm: Add information about polarity, duty cycle and period to debugfs pwm: Switch to the atomic API pwm: Update documentation pwm: Add core infrastructure to allow atomic updates pwm: Add hardware readout infrastructure pwm: Move the enabled/disabled info into pwm_state pwm: Introduce the pwm_state concept pwm: Keep PWM state in sync with hardware state ARM: Explicitly apply PWM config extracted from pwm_args drm: i915: Explicitly apply PWM config extracted from pwm_args input: misc: pwm-beeper: Explicitly apply PWM config extracted from pwm_args input: misc: max8997: Explicitly apply PWM config extracted from pwm_args backlight: lm3630a: explicitly apply PWM config extracted from pwm_args backlight: lp855x: Explicitly apply PWM config extracted from pwm_args backlight: lp8788: Explicitly apply PWM config extracted from pwm_args backlight: pwm_bl: Use pwm_get_args() where appropriate fbdev: ssd1307fb: Use pwm_get_args() where appropriate regulator: pwm: Use pwm_get_args() where appropriate leds: pwm: Use pwm_get_args() where appropriate input: misc: max77693: Use pwm_get_args() where appropriate ... 2016-05-20T18:00:43Z Ricky Liang jcliang@chromium.org 2016-05-20T17:58:59Z urn:sha1:affa80bd97f7ca282d1faa91667b3ee9e4c590e6 When running a 32-bit userspace on a 64-bit kernel, the UI_SET_PHYS ioctl needs to be treated with special care, as it has the pointer size encoded in the command.

Use pwm_get_args() when the PWM user wants to retrieve this reference config and not the current state. This is part of the rework allowing the PWM framework to support hardware readout and expose real PWM state even when the PWM has just been requested (before the user calls pwm_config/enable/disable()).
