linux-toradex.git/drivers/gpu/drm/gma500/opregion.c, branch v3.10 Linux kernel for Apalis and Colibri modules gma500/cdv: Add eDP support 2012-08-23T23:29:25+00:00 Zhao Yakui yakui.zhao@intel.com 2012-08-08T13:55:55+00:00 d112a8163f83752361dd639a9a579ae5cc05c6cf Introduce the eDP support into the driver. This has been reworked a bit because kernel driver proper uses encoder/connectors while the legacy Intel driver uses the old output stuff. It also diverges on the backlight handling. The legacy Intel driver adds a panel abstraction based upon the i915 one. It's only really used for backlight bits and we have a perfectly good backlight abstraction which can extend instead.

Introduce the eDP support into the driver.

This has been reworked a bit because kernel driver proper uses encoder/connectors
while the legacy Intel driver uses the old output stuff.

It also diverges on the backlight handling. The legacy Intel driver adds a panel
abstraction based upon the i915 one. It's only really used for backlight bits
and we have a perfectly good backlight abstraction which can extend instead.

Again this is a regression fix where the ordering of handling was disturbed by other work, and the user experience on some boxes is a blank screen.
