Durgadoss R c56f5c0342 Thermal: Make Thermal trip points writeable
Some of the thermal drivers using the Generic Thermal Framework
require (all/some) trip points to be writeable. This patch makes
the trip point temperatures writeable on a per-trip point basis,
and modifies the required function call in thermal.c. This patch
also updates the Documentation to reflect the new change.

Viresh Kumar b9c7aff481 drivers/thermal/spear_thermal.c: add Device Tree probing capability
SPEAr platforms now support DT and so must convert all drivers to support
DT.  This patch adds DT probing support for SPEAr thermal sensor driver
and updates its documentation too.

Also, as SPEAr is the only user of this driver and is only available with
DT, make this an only DT driver.  So, platform_data is completely removed
and passed via DT now.

thermal_zone_device_register() never returns NULL, on error it returns and
ERR_PTR().

Viresh Kumar de716e32e6 thermal/spear_thermal: replace readl/writel with lighter _relaxed variants
readl/writel versions for ARM contain memory barrier instruction for
synchronizing DMA buffers.  These are not required at least on this
module.  So use lighter _relaxed variants.

Vincenzo Frascino 6a92c36688 thermal: add support for thermal sensor present on SPEAr13xx machines
ST's SPEAr13xx machines are based on CortexA9 ARM processors.  These
machines contain a thermal sensor for junction temperature monitoring.

This patch adds support for this thermal sensor in existing thermal
framework.
