Per our discussion please find below an updated patch with corrected
register sizes.
Vaibhav, I have changed the AM335x register size for timers to be 1KB
instead of 4KB to align with the AM335x HWMOD. I have boot tested on
the AM335x.
Cheers
Jon

Subject: [PATCH] ARM: dts: OMAP: Add timer nodes
Add the 12 GP timers nodes present in OMAP2.
Add the 12 GP timers nodes present in OMAP3.
Add the 11 GP timers nodes present in OMAP4.
Add the 7 GP timers nodes present in AM33xx.
Add documentation for timer properties specific to OMAP.
Thanks to Vaibhav Hiremath for creating the AM33xx timer nodes. I have modified
Vaibhav's original nodes adding information on which timers support a PWM
output.
V5 changes:
- Updated timer register sizes for OMAP2/3/4.
- Modified AM335x timer register size to be 1KB instead of 4KB to align with
HWMOD.

+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:
