53a2b6bd5d imx8m{m,n}-venice-gw7902: add support for GPY111 phy
The TI DP83867 phy has been replaced with the MaxLinear GPY111 phy
due to part availability. Add support for it:
 - increase post-reset time to 300ms per datasheet
 - add tx-delay/rx-delay config

d5cc234154 arm: dts: imx8m*-venice: add gpio hog support
Add gpio hog support for board-specific gpio lines:
- put hogs in u-boot.dtsi so as to keep the regular dts files
  in sync with the kernel. The hogs will not be put in the kernel
  as that makes them un-usable by userspace as well as
  re-initializes them to dt defaults overriding changes which may
  have been done by bootloader commands.
- specify gpio names and initial config
- enable GPIO_HOG

a31de24473 arm64: dts: imx8mm-venice-gw7902: use imx8mm-venice-u-boot.dtsi
Use the common imx8mm-venice-u-boot.dtsi (dtb for the
'DEFAULT_DEVICE_TREE) so that it inherits things like binman.
