drm/tegra: Consolidate runtime PM management of older UAPI codepath

2021-12-16T13:07:08Z

Move runtime PM management of older UAPI code paths into the common place. This removes boilerplate code from client drivers. Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: gr2d: Explicitly control module reset

2021-12-16T13:07:07Z

As of commit 4782c0a5dd88 ("clk: tegra: Don't deassert reset on enabling clocks"), module resets are no longer automatically deasserted when the module clock is enabled. To make sure that the gr2d module continues to work, we need to explicitly control the module reset.

gpu: host1x: Cleanup and refcounting for syncpoints

2021-03-31T15:42:13Z

Add reference counting for allocated syncpoints to allow keeping them allocated while jobs are referencing them. Additionally, clean up various places using syncpoint IDs to use host1x_syncpt pointers instead. Signed-off-by: Mikko Perttunen Signed-off-by: Thierry Reding

drm/tegra: gr2d: Add compatible for Tegra114

drm/tegra: gr2d: Correct swapped device-tree compatibles

2021-01-15T16:18:52Z

The device-tree compatibles are swapped in the code, correct them. Tested-by: Peter Geis Tested-by: Nicolas Chauvet Tested-by: Matt Merhar Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: gr2d: Add tiled PATBASE address register

2020-07-17T14:06:16Z

There are two PATBASE address registers, one for linear layout and other for tiled. The driver's address registers list misses the tiled PATBASE register. Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

gpu: host1x: Rename "parent" to "host"

2020-01-10T15:37:38Z

Rename the host1x clients' parent to "host" because that more closely describes what it is. The parent can be confused with the parent device in terms of the device hierarchy. Subsequent patches will add a new member that refers to the parent in that hierarchy. Signed-off-by: Thierry Reding

drm/tegra: Simplify IOMMU group selection

2019-10-29T14:04:34Z

All the devices that make up the DRM device are now part of the same IOMMU group. This simplifies the handling of the IOMMU attachment and also avoids exhausting the number of IOMMUs available on early Tegra SoC generations. Signed-off-by: Thierry Reding

drm/tegra: Move IOMMU group into host1x client

2019-10-28T10:18:37Z

Handling of the IOMMU group attachment is common to all clients, so move the group into the client to simplify code. Signed-off-by: Thierry Reding
