1Hisilicon hix5hd2 gmac controller
2
3Required properties:
4- compatible: should contain one of the following SoC strings:
5	* "hisilicon,hix5hd2-gmac"
6	* "hisilicon,hi3798cv200-gmac"
7	* "hisilicon,hi3516a-gmac"
8	and one of the following version string:
9	* "hisilicon,hisi-gmac-v1"
10	* "hisilicon,hisi-gmac-v2"
11  The version v1 includes SoCs hix5hd2.
12  The version v2 includes SoCs hi3798cv200, hi3516a.
13- reg: specifies base physical address(s) and size of the device registers.
14  The first region is the MAC register base and size.
15  The second region is external interface control register.
16- interrupts: should contain the MAC interrupt.
17- #address-cells: must be <1>.
18- #size-cells: must be <0>.
19- phy-mode: see ethernet.txt [1].
20- phy-handle: see ethernet.txt [1].
21- clocks: clock phandle and specifier pair.
22- clock-names: contain the clock name "mac_core"(required) and "mac_ifc"(optional).
23- resets: should contain the phandle to the MAC core reset signal(optional),
24	the MAC interface reset signal(optional)
25	and the PHY reset signal(optional).
26- reset-names: contain the reset signal name "mac_core"(optional),
27	"mac_ifc"(optional) and "phy"(optional).
28- hisilicon,phy-reset-delays-us: triplet of delays if PHY reset signal given.
29	The 1st cell is reset pre-delay in micro seconds.
30	The 2nd cell is reset pulse in micro seconds.
31	The 3rd cell is reset post-delay in micro seconds.
32
33The MAC address will be determined using the properties defined in
34ethernet.txt[1].
35
36- PHY subnode: inherits from phy binding [2]
