Message-Id: <1371506626-3892-1-git-send-email-soren.brinkmann@xilinx.com> Date: Mon, 17 Jun 2013 15:03:46 -0700 From: Soren Brinkmann <soren.brinkmann@...inx.com> To: Michal Simek <michal.simek@...inx.com>, Mike Turquette <mturquette@...aro.org> Cc: linux-kernel@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, Soren Brinkmann <soren.brinkmann@...inx.com> Subject: [PATCH] clk/zynq/clkc: Add dedicated spinlock for the SWDT 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. Signed-off-by: Soren Brinkmann <soren.brinkmann@...inx.com> --- I don't know how this slipped in... Anyway, the fix depends on armsoc/zynq/clk.
