Subject: MIPS: ath79: Separate AR913x SoC specific WMAC setup code
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6903bb49da18e0bf3e2909e6b1342ee9a26b78ff;p=linux-beck.git

MIPS: ath79: Separate AR913x SoC specific WMAC setup code

The device registration code can be shared between the different SoCs, but
the required setup code varies Move AR913x specific setup code into a
separate function in order to make adding support for another SoCs easier.
