The phy itself is used for both DSI output and CSI input, though the CSI part for the whole chain needs a lot more work, so is left out for now and only the DSI part implemented. This allows the rk3588 with its current VOP support to drive a DSI display using the DSI2 controller driver I'll submit in a next step. Only generic phy interfaces are used, so the DSI part is pretty straight forward. changes in v4: - moved to #phy-cells = 1 as suggested by Sebastian, with the argument denoting the requested phy-type (C-PHY, D-PHY). This works similarly how the Mediatek C/D-PHY already implements this, see mails around: https://lore.kernel.org/all/20230608200552.GA3303349-robh@kernel.org/ - dropped Krzysztof's review tag from the binding because of this - dropped custom UPDATE macro and use FIELD_PREP instead - build a FIELD_PREP_HIWORD macro for the GRF settings - add received Tested-by tags changes in v3: - add Krzysztof review tag to the binding - address Sebastian's review comments - better error handling - dropping empty function - headers - not using of_match_ptr - this should also make the test-robot happier changes in v2: - fix error in dt-binding example - drop unused frequency table - pull in some more recent improvements from the vendor-kernel which includes a lot less magic values - already include the support for rk3576 - use dev_err_probe Heiko Stuebner (2): dt-bindings: phy: Add Rockchip MIPI C-/D-PHY schema phy: rockchip: Add Samsung MIPI D-/C-PHY driver .../phy/rockchip,rk3588-mipi-dcphy.yaml | 87 + drivers/phy/rockchip/Kconfig | 12 + drivers/phy/rockchip/Makefile | 1 + .../phy/rockchip/phy-rockchip-samsung-dcphy.c | 1602 +++++++++++++++++ 4 files changed, 1702 insertions(+) create mode 100644 Documentation/devicetree/bindings/phy/rockchip,rk3588-mipi-dcphy.yaml create mode 100644 drivers/phy/rockchip/phy-rockchip-samsung-dcphy.c
