The driver for S6E63M0 AMOLED LCD panel is not used. It does not
support DeviceTree and respective possible users (S5Pv210 Aquila and
Goni boards) are DeviceTree-only.

-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@xxxxxxxxxxxxxxxxxxxxx
-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@xxxxxxxxxxxxxxxxxxxxx
-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>/).
