We normally runtime suspend when there are displays attached if they
are in the DPMS off state, however, if something wakes the GPU
we send a hotplug event on resume (in case any displays were connected
while the GPU was in suspend) which can cause userspace to light
up the displays again soon after they were turned off.
Prior to
commit 087451f372 ("drm/amdgpu: use generic fb helpers instead of setting up AMD own's."),
the driver took a runtime pm reference when the fbdev emulation was
enabled because we didn't implement proper shadowing support for
vram access when the device was off so the device never runtime
suspended when there was a console bound. Once that commit landed,
we now utilize the core fb helper implementation which properly
handles the emulation, so runtime pm now suspends in cases where it did
not before. Ultimately, we need to sort out why runtime suspend in not
working in this case for some users, but this should restore similar
behavior to before.
v2: move check into runtime_suspend
v3: wake ups -> wakeups in comment, retain pm_runtime behavior in
runtime_idle callback

The ssd130x driver only provides the core support for these devices but it
does not have any bus transport logic. Add a driver to interface over SPI.
There is a difference in the communication protocol when using 4-wire SPI
instead of I2C. For the latter, a control byte that contains a D/C# field
has to be sent. This field tells the controller whether the data has to be
written to the command register or to the graphics display data memory.
But for 4-wire SPI that control byte is not used, instead a real D/C# line
must be pulled HIGH for commands data and LOW for graphics display data.
For this reason the standard SPI regmap can't be used and a custom .write
bus handler is needed.

These are declared in the ssd130x-i2c transport driver but the information
is not I2C specific, and could be used by other SSD130x transport drivers.
Move them to the ssd130x core driver and just set the OF device entries to
an ID that could be used to lookup the correct device info from an array.
While being there, also move the SSD130X_DATA and SSD130X_COMMAND control
bytes. Since even though they are used by the I2C interface, they could
also be useful for other transport protocols such as SPI.

In function si_parse_power_table(), array adev->pm.dpm.ps and its member
is allocated. If the allocation of each member fails, the array itself
is freed and returned with an error code. However, the array is later
freed again in si_dpm_fini() function which is called when the function
returns an error.
This leads to potential double free of the array adev->pm.dpm.ps, as
well as leak of its array members, since the members are not freed in
the allocation function and the array is not nulled when freed.
In addition adev->pm.dpm.num_ps, which keeps track of the allocated
array member, is not updated until the member allocation is
successfully finished, this could also lead to either use after free,
or uninitialized variable access in si_dpm_fini().
Fix this by postponing the free of the array until si_dpm_fini() and
increment adev->pm.dpm.num_ps everytime the array member is allocated.

As defined in the anx7625 dt-binding, the analogix,lane0-swing and
analogix,lane1-swing properties are uint8 arrays. Yet, the driver was
reading the array as if it were of uint32 and masking to 8-bit before
writing to the registers. This means that a devicetree written in
accordance to the dt-binding would have its values incorrectly parsed.
Fix the issue by reading the array as uint8 and storing them as uint8
internally, so that we can also drop the masking when writing the
registers.

Add driver for Lontium LT9211 Single/Dual-Link DSI/LVDS or Single DPI to
Single-link/Dual-Link DSI/LVDS or Single DPI bridge. This chip is highly
capable at converting formats, but sadly it is also highly undocumented.
This driver is written without any documentation from Lontium and based
only on shreds of information available in various obscure example codes,
hence long runs of unknown register patches and lengthy delays in various
places. Whichever register meaning could be divined from its behavior has
at least a comment around it.
Currently the only mode tested is Single-link DSI to Single-link LVDS.
Dual-link LVDS might work as well, the register programming is in place,
but is untested.
