From cf40fbb509eaa53ff787dce41911b2545bd001ea Mon Sep 17 00:00:00 2001
From: Gabor Juhos <juhosg@openwrt.org>

Subject: [PATCH] MIPS: ath79: add WMAC registration code for the QCA955X SoCs
commit e9c0d0aaa3a7a6e66135e8b44f3323143a635098 upstream.
The SoC has a built-in wireless MAC. Register a platform
device for that to make it usable with the ath9k driver.
