Update device-tree binding with fixed-link support. With fixed-link support the formerly required property 'phy-handle' is now optional if 'fixed-link' child is present. Signed-off-by: Moritz Fischer <mdf@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>

* NI XGE Ethernet controller
|
|
|
|
Required properties:
|
|
- compatible: Should be "ni,xge-enet-3.00", but can be "ni,xge-enet-2.00" for
|
|
older device trees with DMA engines co-located in the address map,
|
|
with the one reg entry to describe the whole device.
|
|
- reg: Address and length of the register set for the device. It contains the
|
|
information of registers in the same order as described by reg-names.
|
|
- reg-names: Should contain the reg names
|
|
"dma": DMA engine control and status region
|
|
"ctrl": MDIO and PHY control and status region
|
|
- interrupts: Should contain tx and rx interrupt
|
|
- interrupt-names: Should be "rx" and "tx"
|
|
- phy-mode: See ethernet.txt file in the same directory.
|
|
- nvmem-cells: Phandle of nvmem cell containing the MAC address
|
|
- nvmem-cell-names: Should be "address"
|
|
|
|
Optional properties:
|
|
- mdio subnode to indicate presence of MDIO controller
|
|
- fixed-link : Assume a fixed link. See fixed-link.txt in the same directory.
|
|
Use instead of phy-handle.
|
|
- phy-handle: See ethernet.txt file in the same directory.
