[PATCH] b43: implement baseband init for LP-PHY <= rev1

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Implement baseband init for rev.0 and rev.1 LP PHYs. Convert boardflags_hi values to defines. Implement b43_phy_copy for easier copying between registers, as needed by LP-PHY init.
