backlight: ili9320: add missing SPI dependency

2012-10-25T21:37:52+00:00

Add this missing SPI dependency and prevent the driver from building
without SPI, because functions of the spi driver are used in this
driver.

  drivers/video/backlight/ili9320.c:51: undefined reference to `spi_sync'

Also, a prompt string for CONFIG_LCD_ILI9320 is added for explicit
selection.

Merge tag 'for-3.7-rc1' of git://gitorious.org/linux-pwm/linux-pwm

2012-10-10T11:15:24+00:00

Pull pwm changes from Thierry Reding:
 "All legacy PWM providers have now been moved to the PWM subsystem.
  The plan for 3.8 is to adapt all board files to provide a lookup table
  for PWM devices in order to get rid of the global namespace.
  Subsequently, users of the legacy pwm_request() and pwm_free()
  functions can be migrated to the new pwm_get() and pwm_put()
  functions.  Once this has been completed, the legacy API and the
  compatibility code in the core can be removed.

  In addition to the above, these changes also add support for
  configuring the polarity of a PWM signal (currently only supported on
  ECAP and EHRPWM) and include a much needed rework of the i.MX driver.
  Managed functions to obtain and release a PWM device (devm_pwm_get()
  and devm_pwm_put()) have been added and the pwm-backlight driver has
  been updated to use them.  If the PWM subsystem hasn't been enabled,
  dummy functions are provided that allow the subsystem to safely
  compile out.

  Some common checks on input parameters have been moved to the core and
  removed from the drivers.  Finally, a small fix corrects the
  description of the PWM specifier's second cell in the device tree
  representation."

pwm-backlight: Use devm_pwm_get() instead of pwm_get()

2012-10-05T18:56:39+00:00

Managed versions of the pwm_get() and pwm_put() functions were recently
added to the PWM framework. They can be used to simplify cleanup in the
error paths and the device removal callback.

Merge misc patches from Andrew Morton:
 "The MM tree is rather stuck while I wait to find out what the heck is
  happening with sched/numa.  Probably I'll need to route around all the
  code which was added to -next, sigh.

  So this is "everything else", or at least most of it - other small
  bits are still awaiting resolutions of various kinds."

backlight: remove ProGear driver

2012-10-05T18:04:53+00:00

This driver was for the ProGear webpad device which was produced in
2000/2001 and is not available on a market.  I no longer have this
hardware so can not even check how Linux works on it.
