-From dcb5fd2c195981557237e3f91598a6b19f7fe929 Mon Sep 17 00:00:00 2001

-Subject: [PATCH] fix-suspend-backlight-timing-pm-debug.patch
-
-This patch improves the smoothness of suspend and resume action.
-
-Taking out CONFIG_PM_DEBUG allows much more rapid resume (the low level
-serial traffic appears to be synchronous)
-
-Added a platform callback in jbt driver and support in pcf50633 so we
-can defer bringing up the backlight until the LCM is able to process
-video again (which must happen after the glamo is up and producing
-video beacuse the LCM is hooked to glamo SPI)
-
-GTA01 should not be affected by all this as the callback will default
-to null and it is on pcf50606
-
-Signed-off-by: Andy Green <andy@openmoko.com>
