Subject: [PATCH v3 0/2] Add lcd driver for panels with gpio controlled panel reset
Newsgroups: gmane.linux.kernel
Date: Monday 26th March 2012 08:46:38 UTC (over 4 years ago)
Changes since v2:
- Reworked as per comments[1] from Mark Brown.
  - removed the setting of regulator voltage.

[1] http:[email protected]/msg08743.html

Changes since v1:
- Fixed gpio leak, added MODULE_DEVICE_TABLE and dev_pm_ops.
- Changed device tree bindings.

This patchset adds support for passive panels that use a nRESET line which
is
controlled by a GPIO of the host system and which do not use a serial
comamnd
interface (i2c or spi) or memory-mapped-io interface. Platforms that do not
require any additional control apart from the nRESET line can use this
driver
for lcd power control.

The first patch adds driver for passive raster-type lcd's with gpio
controlled
panel reset. It includes support for both dt and non-dt platforms. The
second
patch adds support for using this driver on Origen board.
