[PATCH v2 01/14] dt-bindings: phy: Convert Cadence MHDP PHY bindings to YAML.

From: Yuti Amonkar
Date: Mon Dec 23 2019 - 10:17:00 EST


- Convert the MHDP PHY devicetree bindings to yaml schemas.
- Rename DP PHY to have generic Torrent PHY nomrnclature.
- Rename compatible string from "cdns,dp-phy" to "cdns,torrent-phy".
This will not affect ABI as the driver has never been functional,
and therefore do not exist in any active use case

-Cadence MHDP DisplayPort SD0801 PHY binding
-===========================================
-
-This binding describes the Cadence SD0801 PHY hardware included with
-the Cadence MHDP DisplayPort controller.
-
--------------------------------------------------------------------------------
-Required properties (controller (parent) node):
-- compatible : Should be "cdns,dp-phy"
-- reg : Defines the following sets of registers in the parent
- mhdp device:
- - Offset of the DPTX PHY configuration registers
- - Offset of the SD0801 PHY configuration registers
-- #phy-cells : from the generic PHY bindings, must be 0.
-
-Optional properties:
-- num_lanes : Number of DisplayPort lanes to use (1, 2 or 4)
-- max_bit_rate : Maximum DisplayPort link bit rate to use, in Mbps (2160,
- 2430, 2700, 3240, 4320, 5400 or 8100)
--------------------------------------------------------------------------------
-
-Example:
- dp_phy: phy@f0fb030a00 {
- compatible = "cdns,dp-phy";
- reg = <0xf0 0xfb030a00 0x0 0x00000040>,
- <0xf0 0xfb500000 0x0 0x00100000>;
- num_lanes = <4>;
- max_bit_rate = <8100>;
- #phy-cells = <0>;
- };
