[PATCH] clk/zynq/clkc: Add dedicated spinlock for the SWDT

From: Soren Brinkmann
Date: Mon Jun 17 2013 - 18:04:09 EST


The clk_mux for the system watchdog timer reused the register lock
dedicated to the Ethernet module - for no apparent reason.
Add a lock dedicated to the SWDT's clock register to remove this
wrong dependency.

I don't know how this slipped in...
Anyway, the fix depends on armsoc/zynq/clk.
