Subject: [PATCH 4.2.y-ckt 033/273] ARM: dts: Fix wl12xx missing clocks that cause hangs

4.2.8-ckt5 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Adam Ford <aford173@...il.com>

commit 0ea24daae053a9ba65d2f3eb20523002c1a8af38 upstream.

The tcxo-clock-frequency binding is listed as optional,
but without it the wl12xx used on the torpedo + wireless
may hang.  Scanning also appears broken without this patch.
