Commit Message

Christian Marangi Nov. 29, 2023, 2:12 a.m. UTC
  Almost all the QCA8081 PHY driver OPs are specific and only some of them
use the generic at803x.

To make the at803x code slimmer, move all the specific qca808x regs and
functions to a dedicated PHY driver.

All the shared function are moved to the shared .c since they are both
used by qca808x and at803x.

Also a new Kconfig is introduced QCA808X_PHY, to compile the newly
introduced PHY driver for QCA8081 PHY.
