Subject: [PATCH v2 1/2] riscv: dts: spacemit: Fix phy id check for the phy on pico-itx board
Date: Sun, 26 Jul 2026 07:33:49 +0800	[thread overview]
Message-ID: <20260725233351.55004-2-inochiama@gmail.com> (raw)
In-Reply-To: <20260725233351.55004-1-inochiama@gmail.com>

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.
