-sysfs interface for the S6E63M0 AMOLED LCD panel driver
--------------------------------------------------------
-
-What:		/sys/class/lcd/<lcd>/gamma_mode
-Date:		May, 2010
-KernelVersion:	v2.6.35
-Contact:	dri-devel@lists.freedesktop.org
-Description:
-		(RW) Read or write the gamma mode. Following three modes are
-		supported:
-		0 - gamma value 2.2,
-		1 - gamma value 1.9 and
-		2 - gamma value 1.7.
-
-
-What:		/sys/class/lcd/<lcd>/gamma_table
-Date:		May, 2010
-KernelVersion:	v2.6.35
-Contact:	dri-devel@lists.freedesktop.org
-Description:
-		(RO) Displays the size of the gamma table i.e. the number of
-		gamma modes available.
-
-This is a backlight lcd driver. These interfaces are an extension to the API
-documented in Documentation/ABI/testing/sysfs-class-lcd and in
-Documentation/ABI/stable/sysfs-class-backlight (under
-/sys/class/backlight/<backlight>/).
