Subject: [PATCH v3 09/16] dt-bindings: net: sun7i-gmac: Convert the binding to a schemas
Switch our Allwinner A20 GMAC controller binding to a YAML schema to enable
the DT validation. Since that controller is based on a Synopsys IP, let's
add the validation to that schemas with a bunch of conditionals.
Reviewed-by: Rob Herring <robh@...nel.org>

Changes from v2:
- Switch to phy-connection-type instead of phy-mode
Changes from v1:
- Add a file of its own

-* Allwinner GMAC ethernet controller
-
-This device is a platform glue layer for stmmac.
-Please see stmmac.txt for the other unchanged properties.
-
-Required properties:
- - compatible: Should be "allwinner,sun7i-a20-gmac"
- - clocks: Should contain the GMAC main clock, and tx clock
- The tx clock type should be "allwinner,sun7i-a20-gmac-clk"
- - clock-names: Should contain the clock names "stmmaceth",
- and "allwinner_gmac_tx"
-
-Optional properties:
-- phy-supply: phandle to a regulator if the PHY needs one
-
-Examples:
-
- gmac: ethernet@...0000 {
- compatible = "allwinner,sun7i-a20-gmac";
- reg = <0x01c50000 0x10000>,
- <0x01c20164 0x4>;
- interrupts = <0 85 1>;
- interrupt-names = "macirq";
- clocks = <&ahb_gates 49>, <&gmac_tx>;
- clock-names = "stmmaceth", "allwinner_gmac_tx";
- phy-mode = "mii";
- };
