Subject: [PATCH 1/2] riscv: dts: spacemit: Fix phy id check for the phy on pico-itx board
Date: Sat, 25 Jul 2026 08:58:02 +0800	[thread overview]
Message-ID: <20260725005804.373698-2-inochiama@gmail.com> (raw)
In-Reply-To: <20260725005804.373698-1-inochiama@gmail.com>

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.

Fixes: 74657a376960 ("riscv: dts: spacemit: Add ethernet device for K3")
