This change is done as a follow-up to the following thread:
https://lkml.org/lkml/2014/10/1/436
qcom-wdt is currently assuming the presence of a dedicated node in DT
to gets its configuration. However, on msm architecture, the watchdog is
usually part of the timer block. So this patch-set is changing the driver
and slightly enhancing the timer DT bindings to provide the relevant clocks
and interrupts.

MSM watchdog configuration happens in the same register block as the
timer, so we'll use the same binding as the existing timer.
The qcom-wdt will now be probed when devicetree has an entry compatible
with "qcom,kpss-timer" or "qcom-scss-timer".

Add the watchdog related entries to the Krait Processor Sub-system
(KPSS) timer IPQ8064 devicetree section. Also, add a fixed-clock
description of SLEEP_CLK, which will do for now.

The watchdog has been reworked to use the same DT node as the timer.
This change is updating the device tree doc accordingly.

We can rewrite it for platforms starting with msm8974 and beyond or
delete it and write a new binding. It's a similar hardware block split
out from the timers and then made to use a SPI instead of a PPI for the
interrupt sources. We also lost the CPU remapping feature so there is
really only one watchdog instead of 2 per cpu. Oh and the register
offsets are different, but otherwise the registers are the same.

Subject: [PATCH] Documentation: qcom-wdt: Update binding for individual block
On msm8974 and beyond the KPSS watchdog is split out of the timer
block and made to be a single instance instead of per-cpu. Let's
update the binding to reflect this and replace the binding that
is handled by the qcom,kpss-timer binding.
