8aaacbc0e5 drm: meson: rename driver name to meson-drm
The platform driver name is currently "meson" which can lead to some
confusion, this patch renames it to "meson-drm" and removes the owner
attribute since is always added by __platform_driver_register called by the
module_platform_driver() macro.

e66774dd6f drm/etnaviv: add cmdbuf suballocator
There are 3 big benefits to suballocating a single big DMA buffer
for command submission:

1. Avoid hammering CMA. The old way of allocating and freeing a DMA
   buffer for each submission was hitting some of the real slow
   pathes in CMA, as this allocator was not designed for a concurrent
   small buffers load.

2. Less TLB flushes on IOMMUv2. If a new command buffer is mapped into
   the GPU address space the MMU TLBs need to be flushed. By having
   one big buffer statically mapped to the GPU, a lot of those flushes
   can be avoided.

3. No funky workarounds for GC3000. The FE TLB flush on GC3000 isn't
   reliable. To work around that we tried to lay out the cmdbufs in
   the GPU address space in a way to avoid this issue. This hasn't
   always worked if the address space is crowded. A single statically
   mapped buffer avoids the erratum completely.

d46450737c drm/etnaviv: always flush MMU TLBs on map/unmap
This ensures that the GPU isn't able to write into already freed
objects, as doing this in the IOVA reaper isn't enough, as the
gem_free_object path will also cause unmaps to happen.

On MMUv2 this also ensures that stale entries, which may have
been prefetched into the TLB will be purged.

The flush is low overhead, as it gets batched up with the next
user command buffer, so this isn't incuring an overhead for
each buffer map/unmap.

e41456bfc8 drm/exynos: g2d: prevent integer overflow in
The size computations done in the ioctl function use an integer.
If userspace submits a request with req->cmd_nr or req->cmd_buf_nr
set to INT_MAX, the integer computations overflow later, leading
to potential (kernel) memory corruption.

Prevent this issue by enforcing a limit on the number of submitted
commands, so that we have enough headroom later for the size
computations.

Note that this change has no impact on the currently available
users in userspace, like e.g. libdrm/exynos.

While at it, also make a comment about the size computation more
detailed.

8646dcb8a0 drm/exynos: fix a timeout loop
We were trying to print an error message if we timed out here, but the
loop actually ends with "tries" set to UINT_MAX and not zero.  Fix this
by changing from tries-- to --tries.

A for loop would actually be the most natural way to do this.  My fix
means we only loop 99 times instead of 100 but that's probably ok.

41cbf0fdaa drm/exynos: use atomic helper commit
This patch replaces specific atomic commit function
with atomic helper commit one.

For this, it removes existing atomic commit function
and relevant code specific to Exynos DRM and makes
atomic helper commit to be used instead.

Below are changes for the use of atomic helper commit:
- add atomic_commit_tail callback specific to Exynos DRM
  . default implemention of atomic helper doesn't mesh well
    with runtime PM so the device driver which supports runtime
    PM should call drm_atomic_helper_commit_modeset_enables function
    prior to drm_atomic_helper_commit_planes function call.
    atomic_commit_tail callback implements this call ordering.
- allow plane commit only in case that CRTC device is enabled.
  . for this, it calls atomic_helper_commit_planes function
    with DRM_PLANE_COMMIT_ACTIVE_ONLY flag in atomic_commit_tail callback.

9cc2a68519 drm: zte: add function to configure vou_ctrl dividers
The clock control module (CRM) cannot always provide desired frequency
for all VOU output devices.  That's why VOU integrates a few dividers
to further divide the clocks from CRM.  Let's add an interface for
configuring these dividers.

Although data in struct vou_inf is defined per output device, it doesn't
belong to the device itself but VOU control module.  All these data can
just be defined in VOU driver, and output device driver only needs to
invoke VOU driver function with device ID to enable/disable specific

It enables VOU VL (Video Layer) to support overlay plane with scaling
function.  VL0 has some quirks on scaling support.  We choose to skip it
and only adds VL1 and VL2 into DRM core for now.

7254b1f91e drm: zte: add .atomic_disable hook to disable graphic layer
There are a few hardware bits for each graphic layer to control main/aux
channel and clock selection, as well as the layer enabling.  These bits
sit outside the layer block itself, but in VOU control glue block.  We
currently set these bits up at CRTC initialization for once, and do not
support disabling the layer.

This patch creates a pair of functions zx_vou_layer_enable[disable] to
be invoked from plane hooks .atomic_update and .atomic_disable to set up
and tear down the layer.  This is generic for both graphic and video
layers, so it will make the overlay plane support to be added later much
easier.

98ae9869d1 drm: zte: make zx_plane accessible from zx_vou driver
Move struct zx_plane from zx_plane.c to zx_plane.h, so that it can be
accessed from zx_vou driver, and we can save the use of struct
zx_layer_data completely.  More importantly, those additional data used
by VOU controller to enable/disable graphic and video layers can later
be added and accessed much more easily from zx_vou driver.

While at it, we make two changes to zx_plane_init() interface:

 - Encode struct device pointer in zx_plane, so that we do not need to
   pass it as a parameter.
 - Change return of zx_plane_init() from struct drm_plane pointer to
   error code, since we can get the pointer from zx_plane in zx_vou
   driver now.

ttm_bo_init checks that the reservation object is locked. This is
the caller's responsibility when resv != NULL. Otherwise, the inline
reservation object of the newly allocated buffer is used and must

Uninterruptible w/w locks without an acquire context are always
successful.
