In boards, the dm9000 chip's power and reset can be controlled by gpio. It makes sense to add them to the dm9000 driver and let dt be used to enable power and reset the phy.

Davicom DM9000 Fast Ethernet controller
|
|
|
|
Required properties:
|
|
- compatible = "davicom,dm9000";
|
|
- reg : physical addresses and sizes of registers, must contain 2 entries:
|
|
first entry : address register,
|
|
second entry : data register.
|
|
- interrupt-parent : interrupt controller to which the device is connected
|
|
- interrupts : interrupt specifier specific to interrupt controller
|
|
|
|
Optional properties:
|
|
- davicom,no-eeprom : Configuration EEPROM is not available
|
|
- davicom,ext-phy : Use external PHY
|
|
- reset-gpios : phandle of gpio that will be used to reset chip during probe
|
|
- vcc-supply : phandle of regulator that will be used to enable power to chip
|
|
|
|
Example:
|
|
|
|
ethernet@18000000 {
|
|
compatible = "davicom,dm9000";
|
|
reg = <0x18000000 0x2 0x18000004 0x2>;
|
|
interrupt-parent = <&gpn>;
|
|
interrupts = <7 4>;
|
|
local-mac-address = [00 00 de ad be ef];
|
|
davicom,no-eeprom;
|
|
reset-gpios = <&gpf 12 GPIO_ACTIVE_LOW>;
|
|
vcc-supply = <ð0_power>;
|
|
};
