[PATCH 4.1 30/84] ath10k: fix qca61x4 hw2.1 support

From: Greg Kroah-Hartman
Date: Fri Aug 14 2015 - 14:26:57 EST

4.1-stable review patch. If anyone has any objections, please let me know.


From: Michal Kazior <michal.kazior@xxxxxxxxx>

commit 11a002efbaa7fbd9f6e616695ab42aa9f1caf060 upstream.

During initialization firmware does some sort of
memory switch between DRAM and IRAM. If
configuration value for bank switching isn't
correct device crashes during init.

The new value prevents firmware (and
possibly others) for qca61x4 hw2.1 from crashing
during init.
