[PATCH 0/2] riscv: dts: spacemit: Fix phy id check for the phy

[Inochi Amaoto]

As reported, the phy framework can not detected the phy id correctly
when reiniting this. So add the phy id compatible string to the
etherenet phy, so the phy can be reinit successfully.

Note: separate this patchset as two patch for backport if necessary.

[PATCH 1/2] riscv: dts: spacemit: Fix phy id check for the phy on pico-itx board

[Inochi Amaoto]

Current phy framework can not reinit the phy correctly, as it will
assert the phy reset GPIO so the phy id can not be readed. Setting
the phy id of board pico-itx manually so the phy id dectection can
be skipped.

Looks good to me, aside from commit message spelling and grammar nits
("re-initialize", "read", "detection"). Yixun may just fix in-flight, my
R-by and T-by tags can stay.
