This commit adds support for both DSI outputs found on Tegra. Only very minimal functionality is implemented, so advanced features like ganged mode won't work. Due to the lack of other test hardware, some sections of the driver are hardcoded to work with Dalmore. Signed-off-by: Thierry Reding <treding@nvidia.com>
