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

Newsgroups dev.linux.lists.spacemit,org.infradead.lists.linux-riscv,org.kernel.vger.linux-devicetree,org.kernel.vger.linux-kernel
Message-ID <[email protected]>
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.
