      backlight: add backlight type · bb7ca747
      Matthew Garrett authored
      There may be multiple ways of controlling the backlight on a given
      machine.  Allow drivers to expose the type of interface they are
      providing, making it possible for userspace to make appropriate policy
      decisions.

      ACPI: video: Add dev argument for backlight_device_register · 519ab5f2
      Yu Luming authored
      This patch set adds generic abstract layer support for acpi video driver to
      have generic user interface to control backlight and output switch control by
      leveraging the existing backlight sysfs class driver, and by adding a new
      video output sysfs class driver.
      
      This patch:
      
      Add dev argument for backlight_device_register to link the class device to
      real device object.  The platform specific driver should find a way to get the
      real device object for their video device.

      [PATCH] backlight: Backlight Class Improvements · 6ca01765
      Richard Purdie authored
      Backlight class attributes are currently easy to implement incorrectly.
      Moving certain handling into the backlight core prevents this whilst at the
      same time makes the drivers simpler and consistent.  The following changes are
      included:
      
      The brightness attribute only sets and reads the brightness variable in the
      backlight_properties structure.
      
      The power attribute only sets and reads the power variable in the
      backlight_properties structure.
      
      Any framebuffer blanking events change a variable fb_blank in the
      backlight_properties structure.
      
      The backlight driver has only two functions to implement.  One function is
      called when any of the above properties change (to update the backlight
      brightness), the second is called to return the current backlight brightness
      value.  A new attribute "actual_brightness" is added to return this brightness
      as determined by the driver having combined all the above factors (and any
      driver/device specific factors).
      
      Additionally, the backlight core takes care of checking the maximum brightness
      is not exceeded and of turning off the backlight before device removal.
      
      The corgi backlight driver is updated to reflect these changes.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
