* ARC EMAC 10/100 Ethernet platform driver for Rockchip RK3036/RK3066/RK3188 SoCs |
|
|
|
Required properties: |
|
- compatible: should be "rockchip,<name>-emac" |
|
"rockchip,rk3036-emac": found on RK3036 SoCs |
|
"rockchip,rk3066-emac": found on RK3066 SoCs |
|
"rockchip,rk3188-emac": found on RK3188 SoCs |
|
- 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. |
|
|
|
Examples: |
|
|
|
