| * drm/tegra: Detach devices from IOMMU DMA domain on arm32Dmitry Osipenko2018-09-261-0/+12
| | | | | | | | | | | | | | | | | | | | | | All Tegra DRM devices are getting attached to an implicit IOMMU DMA domain if CONFIG_ARM_DMA_USE_IOMMU=y. Since Tegra DRM driver manages IOMMU by itself, the devices must be detached from the implicit domain using arch-specific IOMMU-API. Note that this works only for arm32 and not for arm64, which will remain broken if CONFIG_IOMMU_DMA is enabled.

| | | | | | | | | | | | | | | | The SOR implemented in Tegra194 is subtly different from its predecessor found in Tegra186. Most notably some registers have been moved around so it is no longer compatible. Signed-off-by: Thierry Reding <treding@nvidia.com>

| * drm/tegra: dc: Do not register DC without primary planeThierry Reding2018-09-261-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Tegra194 contains a fourth display controller that does not own any windows. Therefore, we cannot currently assign a primary plane to it which causes KMS to eventually crash. Do not register the display controller if it owns no windows to work around this. Note that we still have to enable and probe the display controller because for some reason all display controllers need to be powered (and/or clocked) before any registers can be accessed in any of the display controllers.

With this conversion, tegra_drm_fb_suspend() and tegra_drm_fb_resume() will not be used anymore. Both of these functions can be removed. Also, in tegra_drm struct's member state will not be used anymore. So this can be removed forever. Fixed one sparse warning.

| * | drm/panel: Make of_drm_find_panel() return an ERR_PTR() instead of NULLBoris Brezillon2018-07-102-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now, the DRM panel logic returns NULL when a panel pointing to the passed OF node is not present in the list of registered panels. Most drivers interpret this NULL value as -EPROBE_DEFER, but we are about to modify the semantic of of_drm_find_panel() and let the framework return -ENODEV when the device node we're pointing to has a status property that is not equal to "okay" or "ok". Let's first patch the of_drm_find_panel() implementation to return ERR_PTR(-EPROBE_DEFER) instead of NULL and patch all callers to replace the '!panel' check by an 'IS_ERR(panel)' one.

| * drm/tegra: Acquire a reference to the IOVA cacheThierry Reding2018-05-171-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IOVA API uses a memory cache to allocate IOVA nodes from. To make sure that this cache is available, obtain a reference to it and release the reference when the cache is no longer needed. On 64-bit ARM this is hidden by the fact that the DMA mapping API gets that reference and never releases it. On 32-bit ARM, however, the DMA mapping API doesn't do that, so allocation of IOVA nodes fails.
