1Hisilicon Fast Ethernet MAC controller
2
3Required properties:
4- compatible: should contain one of the following version strings:
5	* "hisilicon,hisi-femac-v1"
6	* "hisilicon,hisi-femac-v2"
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- phy-mode: see ethernet.txt [1].
18- phy-handle: see ethernet.txt [1].
19- hisilicon,phy-reset-delays-us: triplet of delays if PHY reset signal given.
20	The 1st cell is reset pre-delay in micro seconds.
21	The 2nd cell is reset pulse in micro seconds.
22	The 3rd cell is reset post-delay in micro seconds.
23
24The MAC address will be determined using the optional properties
25defined in ethernet.txt[1].
