Merge tag 'backlight-next-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/backlight 

Pull backlight updates from Lee Jones:
 "Old Drivers
   - Remove driver for S6E63M0
   - Remove driver for LD9040

  Fix-ups
   - Trivial (email address update); adp*_bl
   - Use 'atomic' PWM API; pwm_bl

  Bug Fixes
   - Remove pointless boolen '&ptr' check; lm3639_bl"

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>/).
