dt-bindings: net: sun8i-emac: Convert the binding to a schemas
Switch our Allwinner H3 EMAC 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.

* Allwinner sun8i GMAC ethernet controller
|
||||
|
||||
This device is a platform glue layer for stmmac.
|
||||
Please see stmmac.txt for the other unchanged properties.
|
||||
|
||||
Required properties:
|
||||
- compatible: must be one of the following string:
|
||||
"allwinner,sun8i-a83t-emac"
|
||||
"allwinner,sun8i-h3-emac"
|
||||
"allwinner,sun8i-r40-gmac"
|
||||
"allwinner,sun8i-v3s-emac"
|
||||
"allwinner,sun50i-a64-emac"
|
||||
"allwinner,sun50i-h6-emac", "allwinner-sun50i-a64-emac"
|
||||
- reg: address and length of the register for the device.
|
||||
- interrupts: interrupt for the device
|
||||
- interrupt-names: must be "macirq"
|
||||
- clocks: A phandle to the reference clock for this device
|
||||
- clock-names: must be "stmmaceth"
|
||||
- resets: A phandle to the reset control for this device
|
||||
- reset-names: must be "stmmaceth"
|
||||
- phy-mode: See ethernet.txt
|
||||
- phy-handle: See ethernet.txt
|
||||
- syscon: A phandle to the device containing the EMAC or GMAC clock register
|
||||
|
||||
Optional properties:
|
||||
- allwinner,tx-delay-ps: TX clock delay chain value in ps.
|
||||
Range is 0-700. Default is 0.
|
||||
Unavailable for allwinner,sun8i-r40-gmac
|
||||
- allwinner,rx-delay-ps: RX clock delay chain value in ps.
|
||||
Range is 0-3100. Default is 0.
|
||||
Range is 0-700 for allwinner,sun8i-r40-gmac
|
||||
Both delay properties need to be a multiple of 100. They control the
|
||||
clock delay for external RGMII PHY. They do not apply to the internal
|
||||
PHY or external non-RGMII PHYs.
|
||||
|
||||
Optional properties for the following compatibles:
|
||||
- "allwinner,sun8i-h3-emac",
|
||||
- "allwinner,sun8i-v3s-emac":
|
||||
- allwinner,leds-active-low: EPHY LEDs are active low
|
||||
|
||||
Required child node of emac:
|
||||
- mdio bus node: should be named mdio with compatible "snps,dwmac-mdio"
|
||||
|
||||
Required properties of the mdio node:
|
||||
- #address-cells: shall be 1
|
||||
- #size-cells: shall be 0
|
||||
|
||||
The device node referenced by "phy" or "phy-handle" must be a child node
|
||||
of the mdio node. See phy.txt for the generic PHY bindings.
|
||||
|
||||
The following compatibles require that the emac node have a mdio-mux child
|
||||
node called "mdio-mux":
|
||||
- "allwinner,sun8i-h3-emac"
|
||||
- "allwinner,sun8i-v3s-emac":
|
||||
Required properties for the mdio-mux node:
|
||||
- compatible = "allwinner,sun8i-h3-mdio-mux"
|
||||
- mdio-parent-bus: a phandle to EMAC mdio
|
||||
- one child mdio for the integrated mdio with the compatible
|
||||
"allwinner,sun8i-h3-mdio-internal"
|
||||
- one child mdio for the external mdio if present (V3s have none)
|
||||
Required properties for the mdio-mux children node:
|
||||
- reg: 1 for internal MDIO bus, 2 for external MDIO bus
|
||||
|
||||
The following compatibles require a PHY node representing the integrated
|
||||
PHY, under the integrated MDIO bus node if an mdio-mux node is used:
|
||||
- "allwinner,sun8i-h3-emac",
|
||||
- "allwinner,sun8i-v3s-emac":
|
||||
|
||||
Additional information regarding generic multiplexer properties can be found
|
||||
at Documentation/devicetree/bindings/net/mdio-mux.txt
|
||||
|
||||
Required properties of the integrated phy node:
|
||||
- clocks: a phandle to the reference clock for the EPHY
|
||||
- resets: a phandle to the reset control for the EPHY
|
||||
- Must be a child of the integrated mdio
