Rockchip SoC RK3288 10/100/1000 Ethernet driver(GMAC)
|
|
||||||
|
|
||||||
The device node has following properties.
|
|
||||||
|
|
||||||
Required properties:
|
|
||||||
- compatible: should be "rockchip,<name>-gamc"
|
|
||||||
"rockchip,px30-gmac": found on PX30 SoCs
|
|
||||||
"rockchip,rk3128-gmac": found on RK312x SoCs
|
|
||||||
"rockchip,rk3228-gmac": found on RK322x SoCs
|
|
||||||
"rockchip,rk3288-gmac": found on RK3288 SoCs
|
|
||||||
"rockchip,rk3328-gmac": found on RK3328 SoCs
|
|
||||||
"rockchip,rk3366-gmac": found on RK3366 SoCs
|
|
||||||
"rockchip,rk3368-gmac": found on RK3368 SoCs
|
|
||||||
"rockchip,rk3399-gmac": found on RK3399 SoCs
|
|
||||||
"rockchip,rv1108-gmac": found on RV1108 SoCs
|
|
||||||
- reg: addresses and length of the register sets for the device.
|
|
||||||
- interrupts: Should contain the GMAC interrupts.
|
|
||||||
- interrupt-names: Should contain the interrupt names "macirq".
|
|
||||||
- rockchip,grf: phandle to the syscon grf used to control speed and mode.
|
|
||||||
- clocks: <&cru SCLK_MAC>: clock selector for main clock, from PLL or PHY.
|
|
||||||
<&cru SCLK_MAC_PLL>: PLL clock for SCLK_MAC
|
|
||||||
<&cru SCLK_MAC_RX>: clock gate for RX
|
|
||||||
<&cru SCLK_MAC_TX>: clock gate for TX
|
|
||||||
<&cru SCLK_MACREF>: clock gate for RMII referce clock
|
|
||||||
<&cru SCLK_MACREF_OUT> clock gate for RMII reference clock output
|
|
||||||
<&cru ACLK_GMAC>: AXI clock gate for GMAC
|
|
||||||
<&cru PCLK_GMAC>: APB clock gate for GMAC
|
|
||||||
- clock-names: One name for each entry in the clocks property.
|
|
||||||
- phy-mode: See ethernet.txt file in the same directory.
|
|
||||||
- pinctrl-names: Names corresponding to the numbered pinctrl states.
|
|
||||||
- pinctrl-0: pin-control mode. can be <&rgmii_pins> or <&rmii_pins>.
|
|
||||||
- clock_in_out: For RGMII, it must be "input", means main clock(125MHz)
|
|
||||||
is not sourced from SoC's PLL, but input from PHY; For RMII, "input" means
|
|
||||||
PHY provides the reference clock(50MHz), "output" means GMAC provides the
|
|
||||||
reference clock.
|
|
||||||
- snps,reset-gpio gpio number for phy reset.
|
|
||||||
- snps,reset-active-low boolean flag to indicate if phy reset is active low.
|
|
||||||
- assigned-clocks: main clock, should be <&cru SCLK_MAC>;
|
|
||||||
- assigned-clock-parents = parent of main clock.
|
|
||||||
can be <&ext_gmac> or <&cru SCLK_MAC_PLL>.
|
|
||||||
|
|
||||||
Optional properties:
|
|
||||||
- tx_delay: Delay value for TXD timing. Range value is 0~0x7F, 0x30 as default.
|
|
||||||
- rx_delay: Delay value for RXD timing. Range value is 0~0x7F, 0x10 as default.
|
|
||||||
- phy-supply: phandle to a regulator if the PHY needs one
|
|
||||||
|
|
||||||

|
|
||||||
|
|
||||||
gmac: ethernet@ff290000 {
