* video: Allow simple-panel to be used without regulatorsSimon Glass2016-03-171-8/+10
| | | | | | | | | At present simple-panel requires regulator support and will not build without it. But some panels do not have a power supply, or at least not one that can be controlled. Update the implementation to cope with this. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>
* tegra: nyan-big: Move the LCD driver to driver modelSimon Glass2016-02-161-0/+1
| | | | | | | | | | Adjust the driver to use driver model. The SOR becomes a bridge device. We use the normal simple_panel driver to handle the display itself. We also need to enable some options such as regulators, PWMs and DM_VIDEO itself.

* video: panel: Add a simple panel driverSimon Glass2016-01-211-0/+99
Most panels are very simple - they just have a power supply and a backlight. Add a driver which supports this and implements the enable_backlight() method. Signed-off-by: Simon Glass <sjg@chromium.org>
