+Subject: [PATCH 21/27] 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.
