[PATCH v2 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 re-initialize 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.

Changed from v1:
- https://lore.kernel.org/spacemit/20260725005804.373698-1-inochiama@gmail.com
1. Remove all the c22 fallback compatible.

[PATCH v2 1/2] riscv: dts: spacemit: Fix phy id check for the phy on pico-itx board

[Inochi Amaoto]

Current phy framework can not re-initialize the phy correctly, as it will
assert the phy reset GPIO so the phy id can not be read. Setting the
phy id of board pico-itx manually so the phy id detection can be skipped.
