Re: [PATCH v1 0/4] add syscon requirement for mt7988

Some nodes require the syscon fallback at least in u-boot when using
OF_UPSTREAM.

This is because uboot driver uses syscon_node_to_regmap in mtk_eth.c for
"mediatek,toprgu", "mediatek,xfi_pll" and reset pointing to watchdog-node.

I wonder what's the major blocker here to modify the u-boot driver to take
the upstream devicetree as-is, instead of using syscon_node_to_regmap?

Angelo
