drm/v3d: Add missing implicit synchronization.
It is the expectation of existing userspace (X11 + Mesa, in
particular) that jobs submitted to the kernel against a shared BO will
get implicitly synchronized by their submission order. If we want to
allow clever userspace to disable implicit synchronization, we should
do that under its own submit flag (as amdgpu and lima do).
Note that we currently only implicitly sync for the rendering pass,
not binning -- if you texture-from-pixmap in the binning vertex shader
(vertex coordinate generation), you'll miss out on synchronization.

drm/v3d: Add support for compute shader dispatch.
The compute shader dispatch interface is pretty simple -- just pass in
the regs that userspace has passed us, with no CLs to run. However,
with no CL to run it means that we need to do manual cache flushing of
the L2 after the HW execution completes (for SSBO, atomic, and
image_load_store writes that are the output of compute shaders).
This doesn't yet expose the L2 cache's ability to have a region of the
address space not write back to memory (which could be used for
shared_var storage).
So far, the Mesa side has been tested on V3D v4.2 simpenrose (passing
the ES31 tests), and on the kernel side on 7278 (failing atomic
compswap tests in a way that doesn't reproduce on simpenrose).
v2: Fix excessive allocation for the clean_job (reported by Dan
Carpenter). Keep refs on jobs until clean_job is finished, to

iommu: io-pgtable: Add ARM Mali midgard MMU page table format
ARM Mali midgard GPU is similar to standard 64-bit stage 1 page tables, but
have a few differences. Add a new format type to represent the format. The
input address size is 48-bits and the output address size is 40-bits (and
possibly less?). Note that the later bifrost GPUs follow the standard
64-bit stage 1 format.
The differences in the format compared to 64-bit stage 1 format are:
The 3rd level page entry bits are 0x1 instead of 0x3 for page entries.
The access flags are not read-only and unprivileged, but read and write.
This is similar to stage 2 entries, but the memory attributes field matches
stage 1 being an index.
The nG bit is not set by the vendor driver. This one didn't seem to matter,
but we'll keep it aligned to the vendor driver.

dt-bindings: display: amlogic, meson-vpu: Add G12A compatible and ports
The Amlogic G12A VPU is very similar to the Amlogic GXM VPU but with :
- an enhanced plane blender, with up to 3 OSD planes
- support for AFBC 1.2 decoder (for Bifrost GPU)
- support display mode up to 4k60@75Hz

dt-bindings: gpu: add bindings for the ARM Mali Bifrost GPU
Add the bindings for the Bifrost family of ARM Mali GPUs.
The Bifrost GPU architecture is similar to the Midgard family,
but with a different Shader Core & Execution Engine structures.
Bindings are based on the Midgard family bindings, but the inner
architectural changes makes it a separate family needing separate
bindings.
The Bifrost GPUs are present in a number of recent SoCs, like the
Amlogic G12A Family, and many other vendors.
The Amlogic vendor specific compatible is added to handle the
specific IP integration differences and dependencies.

drm/cirrus: rewrite and modernize driver.
Time to kill some bad sample code people are copying from ;)
This is a complete rewrite of the cirrus driver. The cirrus_mode_set()
function is pretty much the only function which is carried over largely
unmodified. Everything else is upside down.
It is a single monster patch. But given that it does some pretty
fundamental changes to the drivers workflow and also reduces the code
size by roughly 70% I think it'll still be alot easier to review than a
longish baby-step patch series.
Changes summary:
- Given the small amout of video memory (4 MB) the cirrus device has
the rewritten driver doesn't try to manage buffers there. Instead
it will blit (memcpy) the active framebuffer to video memory.
- All gem objects are stored in main memory and are manged using the
new shmem helpers. ttm is out.
- It supports RG16, RG24 and XR24 formats. XR24 gets converted to RG24
or RG16 at blit time if needed, to avoid the pitch becoming larger
than what the cirrus hardware can handle.
- The simple display pipeline is used.
- The generic fbdev emulation is used.
- It's a atomic driver now.
- It runs wayland.
