2012-06-01apple-gmux: Fix up the suspend/resume patchMatthew Garrett
I incorporated the wrong version of the suspend/resume patch for gmux, and so lost David Woodhouse's fix to leave the backlight level unchanged over suspend/resume. This fixes it up to v2. Signed-off-by: Matthew Garrett <mjg@redhat.com>
2012-05-31apple-gmux: Add suspend/resume support for the backlightSeth Forshee
After S3, the brightness might not be restored to the pre-suspend value. Request status update calls from the backlight core on suspend/resume to ensure the brightness value is restored.

Apple laptops with hybrid graphics have a device named gmux that controls the muxing of the LVDS panel between the GPUs as well as screen brightness. This driver adds support for the gmux device. Only backlight control is supported initially.
