drm: Add NVIDIA Tegra20 support This commit adds a KMS driver for the Tegra20 SoC. This includes basic support for host1x and the two display controllers found on the Tegra20 SoC. Each display controller can drive a separate RGB/LVDS output.

drm/tegra: Increase compile test coverage The ARCH_MULTIPLATFORM dependency was introduced back when Tegra didn't support multiplatform yet as a means to allow the driver to be easily compile-tested along with other DRM drivers. In the meantime, the new COMPILE_TEST Kconfig option has been introduced for exactly that purpose, so use that instead to clarify the intention. Signed-off-by: Thierry Reding <treding@nvidia.com>

drm/tegra: Add DSI support 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>

drm/tegra: Unconditionally select IOMMU_IOVA Currently configurations can be generated where IOMMU_SUPPORT is disabled but IOMMU_IOVA is built as a module and DRM_TEGRA as built-in. In such a case, the symbols guarded by IOMMU_IOVA will not be available when linking the Tegra DRM driver and cause a linking failure. Simplify this by unconditionally selecting IOMMU_IOVA, which makes sure that it will be forced to =y if DRM_TEGRA=y. Technically we can now get IOMMU_IOVA code built-in even if we don't use it (Tegra DRM only uses it when IOMMU_SUPPORT is also enabled), but such configuration are of a mostly academic nature. In all practical configurations we want IOMMU support anyway. Signed-off-by: Thierry Reding <treding@nvidia.com>

drm/tegra: hdmi: Add cec-notifier support In order to support CEC the HDMI driver has to inform the CEC driver whenever the physical address changes. So when the EDID is read the CEC driver has to be informed and whenever the hotplug detect goes away. This is done through the cec-notifier framework. The link between the HDMI driver and the CEC driver is done through the hdmi-phandle property in the tegra-cec node in the device tree.

Choose this option if you have an NVIDIA Tegra SoC.
To compile this driver as a module, choose M here: the module
will be called tegra-drm.
