Subject: [PATCH net-next 1/2] regmap: mdio: make it depend on PHYLIB
Date: Sun, 15 Mar 2026 17:48:43 +0100 [thread overview]
Message-ID: <a21a3b3e-272e-4c61-986e-48a2cb3421d9@gmail.com> (raw)
In-Reply-To: <bc63cf87-3dba-4ab6-9c84-caa7357c3273@gmail.com>
MDIO-based regmap is the last user of config symbol MDIO_BUS.
MDIO access needs a MII bus, which requires PHYLIB for the provider part.
Therefore make REGMAP_MDIO depend on PHYLIB, what allows to remove
config symbol MDIO_BUS in a follow-up patch.
Note: After c5a219395b4e ("regmap: Move selecting for REGMAP_MDIO and
REGMAP_IRQ") switching to "depends on" should be fine, w/o risk
of a circular dependency.
