-Subject: [PATCH 17/27] MIPS: ath79: add support for qca956x soc
-
-This patch adds soc support for QCA9561 and TP9343.
-TP9343 is a reduced version of QCA9561, which can be found in TP-LINK routers in China.
-The qca956x_wmac has not yet been supported by ath9k.
-
-tested on TL-WDR6500 and TL-WR882N v1 (Chinese version)
