From David Brown:
Patches for MSM core

These patches are changes to the MSM timer code that will be for
upcoming targets, including a generalization of the binding and
preventing a missing timer interrupt.

* tag 'msm-core-3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm:
  ARM: msm: Wait for timer clear to complete
  ARM: msm: Rework timer binding to be more general

 Properties:
 
 - compatible : Should at least contain "qcom,msm-timer". More specific
-  properties such as "qcom,msm-gpt" and "qcom,msm-dgt" specify a general
-  purpose timer and a debug timer respectively.
+               properties specify which subsystem the timers are paired with.
 
-- interrupts : Interrupt indicating a match event.
+               "qcom,kpss-timer" - krait subsystem
+               "qcom,scss-timer" - scorpion subsystem
 
-- reg : Specifies the base address of the timer registers. The second region
-  specifies an optional register used to configure the clock divider.
+- interrupts : Interrupts for the the debug timer, the first general purpose
+               timer, and optionally a second general purpose timer in that
+               order.
 
-- clock-frequency : The frequency of the timer in Hz.
+- reg : Specifies the base address of the timer registers.
+
+- clock-frequency : The frequency of the debug timer and the general purpose
+                    timer(s) in Hz in that order.
 
 Optional:
 
 - cpu-offset : per-cpu offset used when the timer is accessed without the
-  CPU remapping facilities. The offset is cpu-offset * cpu-nr.
+               CPU remapping facilities. The offset is
+               cpu-offset + (0x10000 * cpu-nr).
