Subject: [PATCH net-next v3 2/5] net: phy: Add BIT macro for Motorcomm yt8521/yt8531 gigabit ethernet phy
Add BIT macro for Motorcomm yt8521/yt8531 gigabit ethernet phy.
This is a preparatory patch. Add BIT macro for 0xA012 reg, and
supplement for 0xA001 and 0xA003 reg. These will be used to support dts.
