[GIT PULL] clockevents: new material for 3.16

[daniel.lezcano@linaro.org (Daniel Lezcano)]

Hi Thomas, Ingo,

this time we have a big number of changes in the clockevents.

There is a branch shared between Simon and I with two merges. The first 
merge was to pull the cmt,mtu changes from Laurent into the 
clockevents/cmt-mtu2-tmu-cleanups branch. Then this one has been merged 
in the clockevents/3.16. A bit later, a new fix on top of these changes 
has been provided and applied to clockevents/cmt-mtu2-tmu-cleanups with 
a second merge to clockevents/3.16.

clockevents/cmt-mtu2-tmu-cleanups will stay there until the 3.16 is 
released.

This pull request contains the following changes:

  * Laurent Pinchart did a lot of modifications to prepare the DT 
support. These modifications include a lot of cleanup (structure 
renaming, preparation to support multiple channel, kzalloc usage, ...) 
and then finishes to drop the old code to the new one.

  * Jingoo Han removed the dev_err when an allocation fails because this 
error is already given by the mm subsystems.
	* http://patchwork.ozlabs.org/patch/324158/
         * [conflict resolved] kmalloc => kzalloc changes with cmt,tmu, 
mtu cleanups from Laurent Pinchard

  * Matthew Leach added the ARM global timer with vexpress, enabled the 
ARM global timer with the A5 and added the definition in the DT. He also 
fixed a invalid check when looking for an usable ARM global timer for A9

  * Maxime Ripard added the support for AllWinner A31 for sun4i and made 
the timer reset optional through the DT

  * Stephen Boyd used the msm timer for the udelay

  * Uwe Kleine-K?nig fixed the non-standard 'compatible' binding for efm32

  * Xiubo Li clarified the types for the clocksource_mmio_read* and 
added a new Flextimer Module (FTM) with its bindings

  * Yang Wei added the 'notrace' attribute to 'read_sched_clock' for the 
dw_apb_timer
