2020-03-26drm: Garbage collect drm_dev_finiDaniel Vetter2-2/+0
It has become empty. Given the few users I figured not much point splitting this up. v2: Rebase over i915 changes. v3: Rebase over patch split fix.

2020-03-26drm/mipi_dbi: Use drmm_add_final_kfree in all driversDaniel Vetter7-0/+14
They all share mipi_dbi_release so we need to switch them all together. With this we can drop the final kfree from the release function. Aside, I think we could perhaps have a tiny additional helper for these mipi_dbi drivers, the first few lines around devm_drm_dev_init are all the same (except for the drm_driver pointer).

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.

2020-01-19drm: tiny: st7735r: Prepare for adding support for more displaysGeert Uytterhoeven1-14/+53
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.

2019-10-01drm/tiny: Kconfig: Remove always-y THERMAL dep. from TINYDRM_REPAPERUlf Magnusson1-1/+0
Commit 554b3529fe01 ("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.

2019-08-12drm: gm12u320: Do not take a mutex from a wait_event conditionHans de Goede1-12/+2
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.
