Subject: [PATCH v2] dt-bindings: net: qca,ar9331: convert to DT schema
Convert the Qualcomm Atheros AR9331 built-in switch bindings to DT
schema.
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
---
DSA switch bindings still bring me headache...
Changes in v2:
1. Narrow pattern for phy children to ethernet-phy@ or phy@ (MIPS DTS
has the latter) - Conor.

-Atheros AR9331 built-in switch
-=============================
-
-It is a switch built-in to Atheros AR9331 WiSoC and addressable over internal
-MDIO bus. All PHYs are built-in as well.
-
-Required properties:
-
- - compatible: should be: "qca,ar9331-switch"
- - reg: Address on the MII bus for the switch.
- - resets : Must contain an entry for each entry in reset-names.
- - reset-names : Must include the following entries: "switch"
- - interrupt-parent: Phandle to the parent interrupt controller
- - interrupts: IRQ line for the switch
- - interrupt-controller: Indicates the switch is itself an interrupt
- controller. This is used for the PHY interrupts.
- - #interrupt-cells: must be 1
- - mdio: Container of PHY and devices on the switches MDIO bus.
-
-See Documentation/devicetree/bindings/net/dsa/dsa.txt for a list of additional
-required and optional properties.
-Examples:
