Subject: [net-next PATCH v2 1/3] net: mdio: Add helper functions for accessing MDIO devices
Date: Fri, 22 Oct 2021 11:59:12 -0400 [thread overview]
Message-ID: <20211022155914.3347672-1-sean.anderson@seco.com> (raw)
This adds some helpers for accessing non-phy MDIO devices. They are
analogous to phy_(read|write|modify), except that they take an mdio_device
and not a phy_device.
Signed-off-by: Sean Anderson <sean.anderson@seco.com>
