net: eth: cpsw: Correctly attach to GPIO bitbang MDIO driver (f8d56d8f) · Commits · e / devices / android_kernel_xiaomi_markw

When the GPIO bitbang MDIO driver is used instead of the Davinci MDIO driver we need to configure the phy_id string differently. Otherwise this string looks like this "gpio.6" instead of "gpio-0" and the PHY is not found when phy_connect() is called. Signed-off-by:
