 MIPI TX Configuration Module
 ============================
 
-The MIPI TX configuration module controls the MIPI D-PHY.
-
-Required properties:
-- compatible: "mediatek,<chip>-mipi-tx"
-- the supported chips are mt2701, 7623, mt8173 and mt8183.
-- reg: Physical base address and length of the controller's registers
-- clocks: PLL reference clock
-- clock-output-names: name of the output clock line to the DSI encoder
-- #clock-cells: must be <0>;
-- #phy-cells: must be <0>.
-
-Optional properties:
-- drive-strength-microamp: adjust driving current, should be 3000 ~ 6000. And
-						   the step is 200.
-- nvmem-cells: A phandle to the calibration data provided by a nvmem device. If
-               unspecified default values shall be used.
-- nvmem-cell-names: Should be "calibration-data"
+See phy/mediatek,dsi-phy.yaml
