Subject: [PATCH net v3 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 support.

It brings 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
register offset and bit define into DT, and enable imx6q/imx6dl
imx6qp/imx6sx/imx6ul/imx7d stop mode support.

Currently, below NXP i.MX boards support wol:
- imx6q/imx6dl/imx6qp sabresd
- imx6sx sabreauto
- imx7d sdb

imx6q/imx6dl/imx6qp sabresd 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
v2 -> v3:
 - driver: suggested by Sascha Hauer, use a struct fec_devinfo for
   abstracting differences between different hardware variants,
   it can give more freedom to describe the differences.
 - imx6/7 dtsi: correct one typo pointed out by Andrew.

Thanks Martin, Andrew and Sascha Hauer for the review.
