Changes since v2: - Reworked as per comments[1] from Mark Brown. - removed the setting of regulator voltage.

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.
