v3-v4
- @Laurent I know I told you I could remove the snps,dphy-frequency on V3 but
it is really useful for me here. I removed all other the proprietary
properties except this one. Do you still think it must be removed?
- Frequency units @Rob

+Synopsys DesignWare MIPI Rx D-PHY block details
+
+Description
+-----------
+
+The Synopsys MIPI D-PHY controller supports MIPI-DPHY in receiver mode.
+Please refer to phy-bindings.txt for more information.
+
+Required properties:
+- compatible : Shall be "snps,dw-dphy-rx".
+- #phy-cells : Must be 1.
+- bus-width : Size of the test interface data bus (8 bits->8 or
+ 12bits->12).
+- snps,dphy-frequency : Frequency at which D-PHY should start, configurable.
+ Check Synopsys databook. (-kHz)
+- reg : Test interface register. This correspondes to the
+ physical base address of the controller and size of
+ the device memory mapped registers; Check Synopsys
+ databook.
+
+Example:
+
+ mipi_dphy_rx1: dphy@d00003040 {
+ compatible = "snps,dw-dphy-rx";
+ #phy-cells = <1>;
+ bus-width = <12>;
+ snps,dphy-frequency = <300000>;
+ reg = <0xd0003040 0x20>;
+ };
