   4 Subject: [PATCH] net: phy: Add BIT macro for Motorcomm yt8521/yt8531 gigabit
   5  ethernet phy
   6
   7 Add BIT macro for Motorcomm yt8521/yt8531 gigabit ethernet phy.
   8  This is a preparatory patch. Add BIT macro for 0xA012 reg, and
   9  supplement for 0xA001 and 0xA003 reg. These will be used to support dts.
