7         and the soc string "hisilicon,hi3516cv300-femac".
8 - reg: specifies base physical address(s) and size of the device registers.
9   The first region is the MAC core register base and size.
10   The second region is the global MAC control register.
11 - interrupts: should contain the MAC interrupt.
12 - clocks: A phandle to the MAC main clock.
13 - resets: should contain the phandle to the MAC reset signal(required) and
14         the PHY reset signal(optional).
15 - reset-names: should contain the reset signal name "mac"(required)
16         and "phy"(optional).
17 - mac-address: see ethernet.txt [1].
18 - phy-mode: see ethernet.txt [1].
19 - phy-handle: see ethernet.txt [1].
20 - hisilicon,phy-reset-delays-us: triplet of delays if PHY reset signal given.
