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- 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.
21 The 1st cell is reset pre-delay in micro seconds.
22 The 2nd cell is reset pulse in micro seconds.
23 The 3rd cell is reset post-delay in micro seconds.

33 resets = <&crg 0xec 0>,<&crg 0xec 3>;
34 reset-names = "mac","phy";
35 mac-address = [00 00 00 00 00 00];
36 phy-mode = "mii";
37 phy-handle = <&phy0>;
38 hisilicon,phy-reset-delays-us = <10000 20000 20000>;
