Changes in v4: - Changed hx8279_set_page() and all other utilities to void (Neil) - Changed hx8279_{on,prepare,unprepare}() to return dsi_ctx.accum_err (Neil) - Switched to devm_drm_panel_alloc() as suggested (Neil) 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.
