When try to run rk3036 kylin board with mainline,
I found the emac ethernet probe failed:
[ 2.324583] loop: module loaded
[ 2.328435] SPI driver spidev has no spi_device_id for rockchip,spidev
[ 2.338688] tun: Universal TUN/TAP device driver, 1.6
[ 2.345397] rockchip_emac 10200000.ethernet: no regulator found
[ 2.351892] rockchip_emac 10200000.ethernet: ARC EMAC detected with id: 0x7fd02
[ 2.359331] rockchip_emac 10200000.ethernet: IRQ is 43
[ 2.364719] rockchip_emac 10200000.ethernet: MAC address is now e6:58:d6:ec:d9:7c
[ 2.396993] mdio_bus Synopsys MII Bus: mdio has invalid PHY address
[ 2.403306] mdio_bus Synopsys MII Bus: scan phy mdio at address 0
[ 2.508656] rockchip_emac 10200000.ethernet: of_phy_connect() failed
[ 2.516334] rockchip_emac 10200000.ethernet: failed to probe arc emac (-19)
This reverts commit 1dabb74971b3 ("ARM: dts: rockchip: restyle emac nodes")
make emac on rk3036 kylin board probe right again:
[ 1.920385] CAN device driver interface
[ 1.925499] rockchip_emac 10200000.ethernet: no regulator found

[ 1.940735] rockchip_emac 10200000.ethernet: IRQ is 42
[ 1.946743] rockchip_emac 10200000.ethernet: MAC address is now 96:7d:4f:0a:69:b3
[ 2.581340] rockchip_emac 10200000.ethernet: connected to Generic PHY phy with id 0xffffc816
