Mixel DSI PHY for i.MX8
|
||||
|
||||
The Mixel MIPI-DSI PHY IP block is e.g. found on i.MX8 platforms (along the
|
||||
MIPI-DSI IP from Northwest Logic). It represents the physical layer for the
|
||||
electrical signals for DSI.
|
||||
|
||||
Required properties:
|
||||
- compatible: Must be:
|
||||
- "fsl,imx8mq-mipi-dphy"
|
||||
- clocks: Must contain an entry for each entry in clock-names.
|
||||
- clock-names: Must contain the following entries:
|
||||
- "phy_ref": phandle and specifier referring to the DPHY ref clock
|
||||
- reg: the register range of the PHY controller
|
||||
- #phy-cells: number of cells in PHY, as defined in
|
||||
Documentation/devicetree/bindings/phy/phy-bindings.txt
|
||||
this must be <0>
|
||||
|
||||
Optional properties:
|
||||
- power-domains: phandle to power domain
|

Example:
|

dphy: dphy@30a0030 {

clocks = <&clk IMX8MQ_CLK_DSI_PHY_REF>;
