Subject: net: phy: broadcom: move shadow 0x1C register accessors to brcmphy.h
X-Git-Tag: firefly_0821_release~176^2~3043^2~241^2~5
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=705314797b8b997554b7e9d0ea7b65a497356e53;p=firefly-linux-kernel-4.4.55.git

net: phy: broadcom: move shadow 0x1C register accessors to brcmphy.h

The shadow register 0x1C is used both by the BCM54xxx PHYs and the
BCM7xxx internal PHYs, move the accessors to a common location so both
drivers can use them.
