[PATCH 1/3] net: stmmac: dwmac-rk: add rk3366 & rk3399-specific data

Roger Chen
2016-07-06T10:51:29Z

Add constants and callback functions for the dwmac on rk3368 socs.
As can be seen, the base structure is the same, only registers and
the bits in them moved slightly.

The device node has following properties.

Required properties:
- - compatible: Can be one of "rockchip,rk3288-gmac", "rockchip,rk3368-gmac"
+ - compatible: Can be one of "rockchip,rk3288-gmac", "rockchip,rk3366-gmac",

- reg: addresses and length of the register sets for the device.
- interrupts: Should contain the GMAC interrupts.
- interrupt-names: Should contain the interrupt names "macirq".
