9843ead08f drm/radeon: add DisplayPort MST support (v2)
This adds initial DP 1.2 MST support to radeon, on CAYMAN
and up in theory.

This is off by default.

v2: agd5f:
- add UNIPHY3 offsets
- move atom cmd table code into atombios_encoders.c
- whitespace cleanup
- replace some magic numbers with proper defines

For MST we need to be able to pick front end encoders
separate from backend, but only for MST, so we need to

875711f0e2 drm/radeon: program auxch directly (v2)
The atombios tables have an unfortunate restriction on only
being able to write 12 bytes, MST really wants 16-bytes here,
and since the hw can do it, we should just write directly to it.

This uses a module option to allow for it now, and maybe
we should provide the old code as a fallback for a while.

v2: (agd5f)
- move registers to a proper register header
- only enable on DCE5+
- enable by default on DCE5+
- Switch pad to aux mode before using it
- reformat instance handling to better match the
  rest of the driver

67ba31d352 drm/radeon: add an output_csc property
This adds the drm property for output csc (e.g.,
transform of output display colorspace).  Currently
only common ones (TV RGB, BT.601, BT.709) are supported,
but bypass and tv rgb are really the only useful ones at
the moment.  Additionally we could expose a user adjustable
matrix in the future.

This commit just adds the property.  The hw support will
be added in subsequent patches.

c6169e49bd drm: adv7511: Refactor power management
Remove the internal dependency on DPMS mode for power management by
using a by a powered state boolean instead, and use the new power off
handler at probe time. This ensure that the regmap cache is properly
marked as dirty when the device is probed, and the registers properly
synced during the first power up.

As a side effect this removes the initialization of current_edid_segment
at probe time, as the field will be initialized when the device is
powered on, at the latest right before reading EDID data.

a5241289c4 drm: adv7511: Fix nested sleep when reading EDID
The EDID read code waits for the read completion interrupt to occur
using wait_event_interruptible(). The condition passed to the macro
reads I2C registers. This results in sleeping with the task state set
to TASK_INTERRUPTIBLE, triggering a WARN_ON() introduced in commit
8eb23b9f35 ("sched: Debug nested sleeps").

Fix this by reworking the EDID read code. Instead of checking whether
the read is complete through I2C reads, handle the interrupt registers
in the interrupt handler and update a new edid_read flag accordingly. As
a side effect both the IRQ and polling code paths now process the
interrupt sources through the same code path, simplifying the code.
