      backlight: Add Epson L4F00242T03 LCD driver · e7fb9c4a
      Alberto Panizzo authored
      The Epson LCD L4F00242T03 is mounted on the Freescale i.MX31 PDK board. 
      Based upon Marek Vasut work in l4f00242t03.c, this driver provides
      basic init and power on/off functionality for this device through the
      sysfs lcd interface.
      
      Unfortunately Datasheet for this device are not available and
      all the control sequences sent to the display were copied from the
      freescale driver that in the i.MX31 Linux BSP.
      
      As in the i.MX31PDK board the core and io suppliers are voltage
      regulators, that functionality is embedded here, but not strict.

      atmel_lcdfb: backlight control · a9a84c37
      David Brownell authored
      On the sam9 EK boards, the LCD backlight is hooked up to a PWM output from
      the LCD controller.  It's controlled by "contrast" registers though.
      
      This patch lets boards declare that they have that kind of backlight
      control.  The driver can then export this control, letting screenblank and
      other operations actually take effect ...  reducing the typically
      substantial power drain from the backlight.
      
      Note that it's not fully cooked
        - doesn't force backlight off during system suspend
        - the "power" and "blank" events may not be done right
      This should be easily added in the future.
