vGEM buffers are useful for passing data between software clients and
hardware renders. By allowing the user to create and attach fences to
the exported vGEM buffers (on the dma-buf), the user can implement a
deferred renderer and queue hardware operations like flipping and then
signal the buffer readiness (i.e. this allows the user to schedule
operations out-of-order, but have them complete in-order).
This also makes it much easier to write tightly controlled testcases for
dma-buf fencing and signaling between hardware drivers.
v2: Don't pretend the fences exist in an ordered timeline, but allocate
a separate fence-context for each fence so that the fences are
unordered.
v3: Make the debug output more interesting, and show the signaled status.
v4: Automatically signal the fence to prevent userspace from
indefinitely hanging drivers.
Testcase: igt/vgem_basic/dmabuf-fence
Testcase: igt/vgem_slow/nohang

The hdmi output in rcar-du uses the i2c slave encoder interface to link
to the adv7511 encoder chip. The kms driver creates encoder and connector
entities that internally uses the drm_encoder_slave_funcs ops provided by
the slave encoder driver.
Change the driver such that it expects a bridge entity instead of a slave
encoder. The hdmi connector code isn't needed anymore as we expect the
adv7511 bridge driver to create/manage the connector.
Note that the kms driver still expects a connector node for hdmi to be
present in DT. This node has no connection to the connector created
by the bridge driver.

By default, if using $debugfs/.../rd to log cmdstream, only the
cmdstream buffers themselves are logged. But in some cases we want
to capture other buffers in the submit (to see VBO's or shaders).

The DSI host and PHY driver currently expects the DT bindings to provide
custom properties "qcom,dsi-host-index" and "qcom,dsi-phy-index" so that
the driver can identify which DSI instance it is.
The binding isn't acceptable, but the driver still needs to figure out
what its instance id. This is now done by storing the mmio starting
addresses for each DSI instance in every SoC version in the driver. The
driver then identifies the index number by trying to match the stored
address with comparing the resource start address we get from DT.
We don't have compatible strings for DSI PHY on each SoC, but only the
DSI PHY type. We only support one SoC version for each PHY type, so we
get away doing the same thing above for the PHY driver. We can revisit
this when we support two SoCs with the same DSI PHY.

Introduce new compatible strings for the top level MDSS wrapper device,
and the MDP5 device.
Previously, the "qcom,mdp5" and "qcom,mdss_mdp" compatible strings
were used to match the top level platform_device (which was also tied
to the top level drm_device struct). Now, these strings are used
to match the MDP5 platform device.
Use "qcom,mdss" as the compatible string for top level MDSS device.
This is now used to match the top level platform_device (which is
tied to the drm_device struct).

The driver currently identifies the GPU components it needs by parsing
a phandle list from the 'gpus' DT property.
This isn't the right binding to go with. So, for now, just search all
device nodes and find the gpu node we need by parsing a list of
compatible strings.
Once we know how to link the kms and gpu drivers, we'll drop this method
and use the correct binding.

For MDP5 based platforms, the master device isn't the MDP5 platform
device, but the top level MDSS device, which is a parent to MDP5 and
interface (DSI, HDMI, eDP etc) devices.
In order to add components on MDP5 platforms, we first need to populate
the MDSS children, locate the MDP5 child, and then parse its ports to
get the display interfaces.

The kms driver currently identifies all the mdss components it needs by
parsing a phandle list from the 'connectors' DT property.
Instead of this, describe a list of ports that the MDP hardware provides
to the external world. These ports are linked to external encoder
interfaces such as DSI, HDMI. These are also the subcomponent devices
that we need add. This description of ports complies with the generic
graph bindings.
The LVDS port is a special case since it is a part of MDP4 itself, and
its output connects directly to the LVDS panel. In this case, we don't
try to add it as a component.
