[PATCH net-next v1] dt-bindings: net: convert qca,ar71xx documentation to yaml

From: Oleksij Rempel
Date: Fri Apr 24 2020 - 01:21:26 EST

Now that we have the DT validation in place, let's convert the device tree
bindings for the Atheros AR71XX over to a YAML schemas.

-Required properties:
-- compatible: Should be "qca,<soc>-eth". Currently support compatibles are:
- qca,ar7100-eth - Atheros AR7100
- qca,ar7240-eth - Atheros AR7240
- qca,ar7241-eth - Atheros AR7241
- qca,ar7242-eth - Atheros AR7242
- qca,ar9130-eth - Atheros AR9130
- qca,ar9330-eth - Atheros AR9330
- qca,ar9340-eth - Atheros AR9340
- qca,qca9530-eth - Qualcomm Atheros QCA9530
- qca,qca9550-eth - Qualcomm Atheros QCA9550
- qca,qca9560-eth - Qualcomm Atheros QCA9560
-
-- reg : Address and length of the register set for the device
-- interrupts : Should contain eth interrupt
-- phy-mode : See ethernet.txt file in the same directory
-- clocks: the clock used by the core
-- clock-names: the names of the clock listed in the clocks property. These are
- "eth" and "mdio".
-- resets: Should contain phandles to the reset signals
-- reset-names: Should contain the names of reset signal listed in the resets
- property. These are "mac" and "mdio"
-
-Optional properties:
-- phy-handle : phandle to the PHY device connected to this device.
-- fixed-link : Assume a fixed link. See fixed-link.txt in the same directory.
- Use instead of phy-handle.
-
-Optional subnodes:
-- mdio : specifies the mdio bus, used as a container for phy nodes
- according to phy.txt in the same directory
-
-Example:
-
-ethernet@1a000000 {
- compatible = "qca,ar9330-eth";
- reg = <0x1a000000 0x200>;
- interrupts = <5>;
- resets = <&rst 13>, <&rst 23>;
- reset-names = "mac", "mdio";
- clocks = <&pll ATH79_CLK_AHB>, <&pll ATH79_CLK_MDIO>;
- clock-names = "eth", "mdio";
-
- phy-mode = "gmii";
-};
