Merge tag 'omap-for-v3.8/cleanup-timer-signed' of git://git.kernel.org/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. By Jon Hunter (32) and others via Tony Lindgren * tag 'omap-for-v3.8/cleanup-timer-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (71 commits) ARM: OMAP3: cm-t3517: use GPTIMER for system clock ARM: OMAP2+: timer: remove CONFIG_OMAP_32K_TIMER ARM: OMAP2+: Fix compiler warning for 32k timer ARM: OMAP: Remove unnecessary inclusion of dmtimer.h ARM: OMAP: Add platform data header for DMTIMERs ARM: OMAP: Remove unnecessary omap_dm_timer structure declaration ARM: OMAP2+: Remove unnecessary local variable in timer code ARM: OMAP: Don't store timers physical address ARM: OMAP: Define omap_dm_timer_prepare function as static ARM: OMAP: Clean-up dmtimer reset code ARM: OMAP: Remove __omap_dm_timer_set_source function ARM: OMAP: Remove unnecessary call to clk_get() ARM: OMAP: Add dmtimer interrupt disable function ARM: OMAP: Fix spurious interrupts when using timer match feature ARM: OMAP: Don't restore DMTIMER interrupt status register ARM: OMAP: Don't restore of DMTIMER TISTAT register ARM: OMAP: Fix dmtimer reset for timer1 ARM: OMAP2+: Don't use __omap_dm_timer_reset() ARM: OMAP2/3: Define HWMOD software reset status for DMTIMERs ARM: OMAP3: Correct HWMOD DMTIMER SYSC register declarations ...

+OMAP Counter-32K bindings

+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 {
+ compatible = "ti,omap2-timer";
+ reg = <0x48304000 0x400>;
+ interrupts = <95>;
+ ti,hwmods = "timer12"
+ ti,timer-alwon;
+ ti,timer-secure;
+};
