If anyone has any objections, please let me know. ------------------ From: Paul Kocialkowski [ Upstream commit 47653e4243f2b0a26372e481ca098936b51ec3a8 ] While the MDIO address of the internal PHY on Allwinner sun8i chips is generally 1, of_mdio_parse_addr is used to cleanly parse the address from the device-tree instead of hardcoding it. A commit reworking the code ditched the parsed value and hardcoded the value 1 instead, which didn't really break anything but is more fragile and not future-proof. Restore the initial behavior using the parsed address returned from the helper.
