The platform-lcd driver depends on platform-specific callbacks to setup the lcd panel. These callbacks are supplied using driver's platform data. But for adding device tree support for platform-lcd driver, providing such callbacks is not possible (without using auxdata). Since the callbacks are usually lcd panel specific, it is possible to include the lcd panel specific setup and control functionality in the platform-lcd driver itself, thereby eliminating the need for supplying platform specific callbacks to the driver. The platform-lcd driver can include support for multiple lcd panels. This patchset removes the need for platform data for platform-lcd driver and adds support which can be used to implement lcd panel specific functionality in the driver. As an example, the support for Hydis hv070wsa lcd panel is added to the platform-lcd driver which is then used on the Exynos4 based Origen board. This currently breaks build for other users of platform-lcd driver. Those can be fixed if this approach is acceptable.
