Input: pwm-beeper - fix - scheduling while atomic

2016-06-01T19:15:49+00:00

commit f49cf3b8b4c841457244c461c66186a719e13bcc upstream.

Pwm config may sleep so defer it using a worker.

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.

Input: pwm-beeper - fix module autoload for OF platform driver

2015-09-03T17:56:20+00:00

This platform driver has a OF device ID table but the OF module
alias information is not created so module autoloading won't work.

Input: pwm-beeper - remove useless call to pwm_config()

2015-03-12T21:53:11+00:00

Calling pwm_config() with a period equal to zero always results in
error (-EINVAL) and pwm chip config method is never called.

Input: pwm-beeper - remove unneeded PWM_BEEPER_PM_OPS define

2015-03-08T05:11:50+00:00

The device->pm pointer is always present so there is no need to do tricks with
conditionally defining the pointer.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

2014-12-17T18:06:02+00:00

Pull input subsystem updates from Dmitry Torokhov:
 "Two new drivers for Elan hardware (for I2C touchpad and touchscreen
  found in several Chromebooks and other devices), a driver for Goodix
  touch panel, and small fixes to Cypress I2C trackpad and other input
  drivers.

  Also we switched to use __maybe_unused instead of gating suspend/
  resume code with #ifdef guards to get better compile coverage"

input: misc: drop owner assignment from platform_drivers

2014-10-20T14:20:40+00:00

A platform_driver does not need to set an owner, it will be populated by the
driver core.

Input: use dev_get_platdata()

2013-12-06T10:06:29+00:00

Use the wrapper function for retrieving the platform data instead
of accessing dev->platform_data directly. This is a cosmetic change
to make the code simpler and enhance the readability.

Input: pwm-beeper - add CONFIG_PM_SLEEP to suspend/resume

2013-08-13T05:32:26+00:00

Add CONFIG_PM_SLEEP to suspend/resume functions to fix the build
warnings when CONFIG_PM_SLEEP is not selected. This is because
sleep PM callbacks defined by SET_SYSTEM_SLEEP_PM_OPS are only used
when the CONFIG_PM_SLEEP is enabled.
