Hi,
that's a nice surprise to see support for this in U-Boot! I was checking
lately and couldn't find anything, so this is warmly welcomed,
especially since there are boards which only have GMAC1 (TV boxes).
I didn't look in much detail yet, but overall this looks pretty nice. I
need to check whether we really need a syscon driver, but it looks
trivial enough, so might not be an issue.
So many thanks for sending, and please have some patience with the review.
Cheers,
Andre

This adds gmac1 controller support for the Allwinner sun55i
(A523/A527/T527) platform. Unlike the gmac0 controller which uses the
older sun8i-emac IP, gmac1 utilizes the Synopsys DesignWare Ethernet QOS
IP block.
In addition to porting the DWC_ETH_QOS_SUNXI driver from upstream Linux,
this series also introduces support for relevant dependencies, including
clocks, pinctrl, and syscon required to make the controller fully
functional.
This was tested on the Radxa Cubie A5E board, and the relevant options
are enabled as well.
