Subject: [PATCH net v2 0/4] net: ethernet: fec: move GPR reigster offset and bit into DT

From: Fugang Duan <fugang.duan@....com>

The commit da722186f654 (net: fec: set GPR bit on suspend by DT configuration) set the GPR reigster offset and bit in driver for wol feature.

It bring trouble to enable wol feature on imx6sx/imx6ul/imx7d platforms that have multiple ethernet instances with different GPR bit for stop mode control. So the patch set is to move GPR reigster offset and bit define into DT, and enable imx6q/imx6dl/imx6sx/imx6ul/imx7d stop mode support.

Currently, below NXP i.MX boards support wol:
- imx6q/imx6dl sabresd
- imx6sx sabreauto
- imx7d sdb

imx6q/imx6dl sarebsd board dts file miss the property "fsl,magic-packet;", so patch#4 is to add the property for stop mode support.


v1 -> v2:
 - driver: switch back to store the quirks bitmask in driver_data
 - dt-bindings: rename 'gpr' property string to 'fsl,stop-mode'
 - imx6/7 dtsi: add imx6sx/imx6ul/imx7d ethernet stop mode property

Thanks Martin and Andrew for the review.
