Signed-off-by: Luis Oliveira --- Changelog 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 .../devicetree/bindings/phy/snps,dw-dphy-rx.txt | 29 ++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 Documentation/devicetree/bindings/phy/snps,dw-dphy-rx.txt diff --git a/Documentation/devicetree/bindings/phy/snps,dw-dphy-rx.txt b/Documentation/devicetree/bindings/phy/snps,dw-dphy-rx.txt new file mode 100644 index 0000000..50603e6 --- /dev/null +++ b/Documentation/devicetree/bindings/phy/snps,dw-dphy-rx.txt @@ -0,0 +1,29 @@ +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.
