Subject: [RFC PATCH net-next 0/2] net: phy: lan87xx: use genphy_read_master_slave function

LAN87xx T1 Phy has the same register field as gigabit phy for reading the
master slave configuration. But the genphy_read_master_slave function has a
check of gigabit phy. So refactored the function in such a way, moved the speed
check to the genphy_read_status function. Analyzed the nxp-tja11xx function for
refactoring, but the register for configuring master/slave is nxp specific
which is not extended phy register.
And analyzed the reusing genphy_setup_master_slave, but for LAN87xx
MASTER_ENABLE is always 1 and Preferred state is always 0. So, I didn't try to
change it.

Arun Ramadoss (2):
  net: phy: exported the genphy_read_master_slave function
  net: phy: lan87xx: use genphy_read_master_slave in read_status
