* tegra: nyan-big: Move the LCD driver to driver modelSimon Glass2016-02-16-194/+235
| | | | | | | | | | 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.

* tegra: lcd: Merge tegra124-lcd.c into display.cSimon Glass2016-02-16-98/+79
| | | | | | | | | | There isn't a lot of benefit of have two separate files. With driver model the code needs to be in the same driver, so it's better to have it in the same file.

* dm: video: Repurpose the 'displayport' uclass to 'display'Simon Glass2016-01-21-17/+10
| | | | | | | | | | | | | | The current DisplayPort uclass is too specific. The operations it provides are shared with other types of output devices, such as HDMI and LVDS LCD displays. Generalise the uclass so that it can be used with these devices as well. Adjust the uclass to handle the EDID reading and conversion to display_timing internally. Also update nyan-big which is affected by this. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Use dev_get_addr() where possibleSimon Glass2015-08-31-2/+1
| | | | | | | | | | This is a convenient way for a driver to get the hardware address of a device, when regmap or syscon are not being used. Change existing callers to use it as an example to others.

* tegra124: video: Add full link training for eDPSimon Glass2015-05-13-64/+1079

* tegra: video: support eDP displays on Tegra124 devicesSimon Glass2015-05-13-0/+457
| | | | | | | | | Connect up the clocks and the eDP driver to make these displays work with Tegra124-based devices. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de> Signed-off-by: Tom Warren <twarren@nvidia.com>
* tegra: video: Add Embedded DisplayPort driverSimon Glass2015-05-13-0/+1265
| | | | | | | | | | This interface is used on laptop devices based on Tegra. Add a driver which provides access to the eDP interface. The driver uses the display port uclass.

* tegra: video: Support serial output resource (SOR) on tegra124Simon Glass2015-05-13-0/+1807
The SOR is required for talking to eDP LCD panels. Add a driver for this which will be used by the DisplayPort driver. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de> Signed-off-by: Tom Warren <twarren@nvidia.com>
