3421a6c409 drm/mipi-dbi: Drop explicit drm_mode_config_cleanup call 
Allows us to drop the drm_driver.release callback from all
drivers, and remove the mipi_dbi_release() function.

This is made possible by a preceeding patch which added a drmm_
cleanup action to drm_mode_config_init(), hence all we need to do to
ensure that drm_mode_config_cleanup() is run on final drm_device
cleanup is check the new error code for _init().

v2: Explain why this cleanup is possible (Laurent).

v3: Use drmm_mode_config_init() for more clarity (Sam, Thomas)

8f2cb9379f drm/gm12u320: Simplify upload work 
Instead of having a work item that never stops (which really should be
a kthread), with a dedicated workqueue to not upset anyone else, use a
delayed work. A bunch of changes:

- We can throw out all the custom wakeup and requeue logic and state
  tracking. If we schedule the work with a 0 delay it'll get
  scheduled immediately.

- Persistent state (frame & draw_status_timeout) need to be moved out
  of the work.

- diff is bigger than the changes, biggest chunk is reindenting the
  work fn because it lost its while loop.

Lots of code deleting as consequence all over. Specifically we can
delete the drm_driver.release code now!

v2: Review from Hans:
- Use mod_delayed_work in the plane update path to make sure we do
  actually schedule immediately). In the worker we still want
  queue_delayed_work, which won't modify the timeout when the work is
  already scheduled. Which is exactly what we want if the work races
  with a plane update.
- Switch to system_long_wq, Hans says on usb2 a plane upload can take
  80 ms.

d1d511d516 drm: tiny: st7735r: Add support for Okaya RH128128T 
Add support for the Okaya RH128128T display to the st7735r driver on
DT-enabled systems.

The RH128128T is a 128x128 1.44" TFT display driven by a Sitronix
ST7715R TFT Controller/Driver.  The latter is very similar to the
ST7735R, and can be handled by the existing st7735r driver.

98823f3794 drm: tiny: st7735r: Prepare for adding support for more displays 
Currently the st7735r driver supports only a single display panel.
Prepare for adding support for other display panels by factoring out the
display-specific parameters in struct st7735r_cfg.

For now, the following parameters can be configured:
  - Display resolution,
  - Horizontal/vertical display offsets,
  - Read-write versus read-only controllers,
  - RGB versus BGR color component ordering.

Rename jd_t18003_t01_pipe_enable() and jd_t18003_t01_pipe_funcs() to
st7735r_pipe_enable() resp. st7735r_pipe_funcs(), as they are not really
specific to the Jianda JD-T18003-T01 display anymore.

dfef959803 drm/tiny: Kconfig: Remove always-y THERMAL dep. from TINYDRM_REPAPER 
Commit 554b3529fe ("thermal/drivers/core: Remove the module Kconfig's
option") changed the type of THERMAL from tristate to bool, so
THERMAL || !THERMAL is now always y. Remove the redundant dependency.

Discovered through Kconfiglib detecting a dependency loop. The C tools
simplify the expression to y before running dependency loop detection,
and so don't see it. Changing the type of THERMAL back to tristate makes
the C tools detect the same loop.

Not sure if running dep. loop detection after simplification can be
called a bug. Fixing this nit unbreaks Kconfiglib on the kernel at
least.

9b61db1aed drm: gm12u320: Do not take a mutex from a wait_event condition 
I made the condition of the wait_event_timeout call in
gm12u320_fb_update_work a helper which takes a mutex to make sure
that any writes to fb_update.run or fb_update.fb from other CPU cores
are seen before the check is done.

This is not necessary as the wait_event helpers contain the necessary
barriers for this themselves.

More over it is harmfull since by the time the check is done the task
is no longer in the TASK_RUNNING state and calling mutex_lock while not
in task-running is not allowed, leading to this warning when the kernel
is build with some extra locking checks enabled:

[11947.450011] do not call blocking ops when !TASK_RUNNING; state=2 set at
               [<00000000e4306de6>] prepare_to_wait_event+0x61/0x190

This commit fixes this by dropping the helper and simply directly
checking the condition (without unnecessary locking) in the
wait_event_timeout call.
