Subject: [PATCH v2 01/14] dt-bindings: phy: Convert Cadence MHDP PHY bindings to YAML.
Date: Mon, 23 Dec 2019 16:15:26 +0100	[thread overview]
Message-ID: <1577114139-14984-2-git-send-email-yamonkar@cadence.com> (raw)
In-Reply-To: <1577114139-14984-1-git-send-email-yamonkar@cadence.com>

- 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>;
-	};
