Some Allwinner chips (notably the D1s/T113 and the A100) have a "combo MIPI DSI D-PHY" which is required when using single-link LVDS0. The same PD0..PD9 pins are used for either DSI or LVDS.
Other than having to use the combo D-PHY, LVDS output is configured in the same way as on older chips. This series enables the sun6i MIPI D-PHY to also work in LVDS mode. It is then configured by the LCD TCON, which allows connecting a single-link LVDS display panel. Changes in v2: - Applied code formatting changes from review comments - Changed "dphy" to "combo-phy" - Made the LVDS setup/teardown functions abort early in case of error (adding a proper return value would require changes in several levels of caller functions; perhaps could be done in a separate patch) - Added the PHY properties to DT bindings - Renamed lvds0_pins to lcd_lvds0_pins - Rebased on top of drm/misc/kernel/for-linux-next Kuba Szczodrzyński (6): phy: allwinner: phy-sun6i-mipi-dphy: Support LVDS in combo D-PHY drm/sun4i: Support LVDS using MIPI DSI combo D-PHY drm/sun4i: Enable LVDS output on sun20i D1s/T113 dt-bindings: display: sun4i: Add D1s/T113 combo D-PHY bindings riscv: dts: allwinner: d1s-t113: Add D-PHY to TCON LCD0 riscv: dts: allwinner: d1s-t113: Add LVDS0 pins .../display/allwinner,sun4i-a10-tcon.yaml | 6 ++ .../boot/dts/allwinner/sunxi-d1s-t113.dtsi | 11 +++ drivers/gpu/drm/sun4i/sun4i_tcon.c | 50 +++++++++++++ drivers/gpu/drm/sun4i/sun4i_tcon.h | 6 ++ drivers/phy/allwinner/phy-sun6i-mipi-dphy.c | 70 ++++++++++++++++++- 5 files changed, 141 insertions(+), 2 deletions(-) -- 2.25.1
