Subject: b43: LCN-PHY: add conditions for few operations
X-Git-Tag: v3.2~422^2~254^2~82
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cf577fc242ea5295f676ae3bf9ecb524d78d9e77;p=platform%2Fkernel%2Flinux-amlogic.git

b43: LCN-PHY: add conditions for few operations

It was not possible to guess the conditions from MMIO dumps. Take them
from brcmsmac code.
