BCM2711 DSI1 doesn't have the issue with the ARM not being
able to write to the registers, therefore remove the DMA
workaround for that compatible string.

DSI0 was partially supported, but didn't register with the main
driver, and the code was inconsistent as to whether it checked
port == 0 or port == 1.
Add compatible string and other support to make it consistent.

Most of the differences between DSI0 and DSI1 are handled through the
ID. However, the BCM2711 DSI is going to introduce one more variable to
the mix and will break some expectations of the earlier, simpler, test.
Let's add a variant structure that will address most of the differences
between those three controllers.

The DSI clocks setup function has been using an array to store the clock
name of either the DSI0 or DSI1 blocks, using the port ID to choose the
proper one.
Let's switch to an snprintf call to do the same thing and simplify the

The DSI1_PHY_AFEC0_PD_DLANE1 and DSI1_PHY_AFEC0_PD_DLANE3 register

(In theory a 4 lane device would work as all lanes would remain

The infoframes are sent at a regular interval as a data island packet,
so we don't need to wait for them to be sent when we're setting them up.
However, we do need to poll when we're enabling since the we can't
update the packet RAM until it has been sent.
Let's add a boolean flag to tell whether we want to poll or not to
support both cases.

The DSI version of the panel behaved instable and close
scrutiny of the vendor driver from the Samsung
GT-S8190 shows a different initialization sequence for
the DSI mode panel than the DPI mode panel.
Make the initialization depend on whether we are in
DSI or DPI mode and handle the differences.
After this the panel on the GT-I8190 becomes much more
stable.
Also spell out some more custom DCS commands found in
the vendor source code to cut down a bit on magic
where we can.

This moves the MCDE bindings over to using the YAML schema
to describe the ST-Ericsson MCDE display controller,
making use of the generic DSI controller schema.
In the process we correct an error in the old text bindings:
the clocks for the SDI host controllers were specified as
part of the main MCDE component while they should be
specified in the DSI host controller subnodes. This was
a leftover from an earlier iteration of the first patch
series adding the MCDE.
We also add the "port" node, we will use this when adding
LCD panels using the direct parallel interface DPI instead
of DSI.

This an incremental refactor towards multiple dma-fence contexts
in virtio-gpu. Since all fences are still allocated using
&virtio_gpu_fence_driver.context, nothing should break and every
processed fence will be signaled.
The overall idea is every 3D context can allocate a number of
dma-fence contexts. Each dma-fence context refers to it's own
timeline.
For example, consider the following case where virgl submits
commands to the GPU (fence ids 1, 3) and does a metadata query with
the CPU (fence id 5). In a different process, gfxstream submits
commands to the GPU (fence ids 2, 4).
fence_id (&dma_fence.seqno) | 1 2 3 4 5
----------------------------------|-----------
fence_ctx 0 (virgl gpu) | 1 3
fence_ctx 1 (virgl metadata query)| 5
fence_ctx 2 (gfxstream gpu) | 2 4
With multiple fence contexts, we can wait for the metadata query
to finish without waiting for the virgl gpu to finish. virgl gpu
does not have to wait for gfxstream gpu. The fence id still is the
monotonically increasing sequence number, but it's only revelant to
the specific dma-fence context.
To fully enable this feature, we'll need to:
- have each 3d context allocate a number of fence contexts. Not
too hard with explicit context initialization on the horizon.
- have guest userspace specify fence context when performing
ioctls.
- tag each fence emitted to the host with the fence context
information. virtio_gpu_ctrl_hdr has padding + flags available,
so that should be easy.
This change goes in the direction specified above, by:
- looking up the virtgpu_fence given a fence_id
- signalling all prior fences in a given context
- signalling current fence

virtio_gpu_fence_event_process sets the last_fence_id and
subsequently calls dma_fence_signal_locked(..).
dma_fence_signal_locked(..) sets DMA_FENCE_FLAG_SIGNALED_BIT,
which is actually checked before &dma_fence_ops.(*signaled) is

The check for last_fence_id is therefore a bit redundant, and
it will not be sufficient to check the last_fence_id for multiple

Fix W=1 warnings about variables assigned but never used.
- One variable is only used when CONFIG_FB_ATY_GENERIC_LCD is defined
Fix so variable is only defined with CONFIG_FB_ATY_GENERIC_LCD
- Several variables was only assigned by a call to aty_ld_le32().
Drop the variables but keep the call to aty_ld_le32() as it may
have unexpected side-effects.
v2:
- Updated subject (Lee)
