9f1e1e14 - drm/rockchip: Add MIPI DSI2 glue driver for RK3588

Mon, 09 Dec 2024 23:10:21 +0000

drm/rockchip: Add MIPI DSI2 glue driver for RK3588This adds the glue code for the MIPI DSI2 bridge on Rockchip SoCs andenables its use on the RK3588.Right now the DSI2 controller is always paired with a DC-phy based on aSamsung IP, so the interface values are set statically for now.This stays true for the upcoming RK3576 as well.Tested-by: Daniel Semkowicz Tested-by: Dmitry Yashin Signed-off-by: Heiko Stuebner Reviewed-by: Andy Yan Signed-off-by: Heiko Stuebner Link: https://patchwork.freedesktop.org/patch/msgid/20241209231021.2180582-4-heiko@sntech.de List of files: /linux-6.15/drivers/gpu/drm/rockchip/Kconfig
