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>/).
