Subject: [PATCH] ath79: add support for booting QCN550x
|
||
|
|
|
||
|
|
Based on wikidevi, QCN550x is a "Dragonfly" like QCA9561 and QCA9563.
|
||
|
|
Treating it as QCA956x seems to work.
|
||
|
|
Tested on Netgear EX7300v2 which boots successfully with
|
||
|
|
the same CPU clock as the stock firmware.
