Merge tag 'omap-for-v3.8/cleanup-timer-signed' of git://git.kernel.or…

…g/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup

Timer clean-up to get us closer to moving timer code to drivers,
and to get rid of CONFIG_OMAP_32K_TIMER and rely on the board
or devicetree provided timer configuration.

Note that these changes are on top of the recent timer fixes.

+OMAP Timer bindings
+
+Required properties:
+- compatible:		Must be "ti,omap2-timer" for OMAP2+ controllers.
+- reg:			Contains timer register address range (base address and
+			length).
+- interrupts: 		Contains the interrupt information for the timer. The
+			format is being dependent on which interrupt controller
+			the OMAP device uses.
+- ti,hwmods:		Name of the hwmod associated to the timer, "timer<X>",
+			where <X> is the instance number of the timer from the
+			HW spec.
+
+Optional properties:
+- ti,timer-alwon:	Indicates the timer is in an alway-on power domain.
+- ti,timer-dsp:		Indicates the timer can interrupt the on-chip DSP in
+			addition to the ARM CPU.
+- ti,timer-pwm: 	Indicates the timer can generate a PWM output.
+- ti,timer-secure: 	Indicates the timer is reserved on a secure OMAP device
+			and therefore cannot be used by the kernel.
+
+Example:
+
+timer12: timer@48304000 {
