Punit Agrawal dd354b84d4 thermal: Bind cooling devices with the correct arguments
When binding cooling devices to thermal zones created from the device
tree the minimum and maximum cooling states are in the wrong order
leading to failure to bind.

Fix the order of cooling states in the call to
thermal_zone_bind_cooling_device to fix this.

Stephen Boyd ca9521b770 thermal: Add braces around suspect code
It looks like this code is missing braces, otherwise the if
statement shouldn't have been indented. Fix it.

Eduardo Valentin 4e5e4705bf thermal: introduce device tree parser
This patch introduces a device tree bindings for
describing the hardware thermal behavior and limits.
Also a parser to read and interpret the data and feed
it in the thermal framework is presented.

This patch introduces a thermal data parser for device
tree. The parsed data is used to build thermal zones
and thermal binding parameters. The output data
can then be used to deploy thermal policies.

This patch adds also documentation regarding this
API and how to define tree nodes to use
this infrastructure.

Note that, in order to be able to have control
on the sensor registration on the DT thermal zone,
it was required to allow changing the thermal zone
.get_temp callback. For this reason, this patch
also removes the 'const' modifier from the .ops
field of thermal zone devices.
