Changes in v3:
- Added support for setting digital gamma parameters and validity check
- Added support for setting analog gamma parameters
- Changed gout_{l,r} to a structure and added a description
- Fixed DSI LPM/HS setting in prepare/unprepare callbacks
- Remove forced panel off in probe function as that was simply
useless
- Renamed function hx8279_check_config to hx8279_check_params
as that is actually checking multiple parameters and not just
basic DDIC configuration
- Moved the GMUX and GOA validation to their own functions to
improve readability
Changes in v2:
- Removed unneeded mipi_dsi_device_unregister() call for secondary
DSI: as the driver is using devm, that's not necessary (CJ)
- Removed superfluous if branch as pointed out by CJ
This series adds a driver for DSI panels using the Himax HX8279 and
HX8279-D DriverICs, and introduces two panels using such a configuration,
the Startek KX070FHFID078, found on some MediaTek Genio Evaluation Kits,
and the Aoly SL101PM1794FOG-v15 usually found on some I.MX8MM boards.
This panel is found on the latest hardware revisions of some MediaTek
Genio Evaluation Kits, and specifically, at least:
- Genio 510 EVK
- Genio 700 EVK
- Genio 1200 EVK
This driver was tested on all of the aforementioned boards.
