[PATCH] [RFC]: video: exynos: Making s6e8ax0 panel driver compliant with CDF
Vikas C Sajjan
vikas.sajjan at linaro.org
Wed Jan 9 01:44:04 PST 2013
From: Vikas Sajjan <vikas.sajjan at linaro.org>
Made necessary changes in s6e8ax0 panel driver as per the CDF-T.
it also removes the dependency on backlight and lcd framework.
