* ARC EMAC 10/100 Ethernet platform driver for Rockchip Rk3066/RK3188 SoCs
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: Should be "rockchip,rk3066-emac" or "rockchip,rk3188-emac"
|
||
|
|
according to the target SoC.
|
||
|
|
- reg: Address and length of the register set for the device
|
||
|
|
- interrupts: Should contain the EMAC interrupts
|
||
|
|
- rockchip,grf: phandle to the syscon grf used to control speed and mode
|
||
|
|
for emac.
|
||
|
|
- phy: see ethernet.txt file in the same directory.
|
||
|
|
- phy-mode: see ethernet.txt file in the same directory.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- phy-supply: phandle to a regulator if the PHY needs one
|
||
|
|
|
||
|
|
Clock handling:
|
||
|
|
- clocks: Must contain an entry for each entry in clock-names.
|
||
|
|
- clock-names: Shall be "hclk" for the host clock needed to calculate and set
|
||
|
|
polling period of EMAC and "macref" for the reference clock needed to transfer
|
||
|
|
data to and from the phy.
|
||
|
|
|
||
|
|
Child nodes of the driver are the individual PHY devices connected to the
|
||
|
|
MDIO bus. They must have a "reg" property given the PHY address on the MDIO bus.
|
||
|
|
|
||
|
