Subject: [RFC PATCH net-next v3 10/15] net: dsa: mt7530: introduce separate
MDIO driver
Split MT7530 switch driver into a common part and a part specific
for MDIO connected switches and multi-chip modules.
Move MDIO-specific functions to newly introduced mt7530-mdio.c while
keeping the common parts in mt7530.c.
In order to maintain compatibility with existing kernel configurations
keep CONFIG_NET_DSA_MT7530 as symbol to select the MDIO-specific driver
while the newly introduced hidden symbol CONFIG_NET_DSA_MT7530_COMMON
is selected by CONFIG_NET_DSA_MT7530.
