gpu: host1x: Cleanup and refcounting for syncpoints

2021-03-31T15:42:13+00:00

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.

drm/tegra: gr2d: Add tiled PATBASE address register

2020-07-17T14:06:16+00:00

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.

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

2020-01-10T15:37:38+00:00

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.

drm/tegra: Simplify IOMMU group selection

2019-10-29T14:04:34+00:00

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.

drm/tegra: Move IOMMU group into host1x client

2019-10-28T10:18:37+00:00

Handling of the IOMMU group attachment is common to all clients, so move
the group into the client to simplify code.

gpu: host1x: Request channels for clients, not devices

2019-10-28T10:18:33+00:00

A struct device doesn't carry much information that a channel might be
interested in, but the client very much does. Request channels for the
clients rather than their parent devices and store a pointer to them
in order to have that information available when needed.

drm/tegra: drop use of drmP.h

2019-08-14T16:31:04+00:00

Drop use of the deprecated drmP.h header file.

For all touched files divide include files into blocks,
and sort them within the blocks.
Fix fallout.
