-Subject: [PATCH 603/660] net: phy: provide full set of accessor functions to
- MMD registers
-
-This adds full set of locked and unlocked accessor functions to read and
-write PHY MMD registers and/or bitfields.
-
-Set of functions exactly matches what is already available for PHY
-legacy registers.
