Subject: [PATCH v2 00/33] thermal: exynos: convert the driver to use per-SoC
 type operations

Hi,

This patch series replaces the hardware registers abstractions in
the Exynos thermal driver by the usage of per-SoC type operations.
Such solution provides simpler, easier to understand code and
allows removal of ~250 LOCs (~11% of the whole source code) from
the driver.  Some other driver improvements are now also possible
thanks to these changes but are scheduled at later time (like
consolidating code for clearing IRQs using INTCLEAR register).

The patchset should not cause any functionality changes.  This
means that unless there are some bugs in the patches itself there
should be no behavior changes for the driver (this also includes
lack of changes in the way hardware is accessed by the driver).

All testing was done on (Exynos4412 SoC based) ODROID U3 board
(some additional patches are needed to make the Exynos thermal
driver work on this hardware).

Depends on:
- 'next' branch of linux-soc-thermal.git kernel tree from Eduardo

Changes since v1 (https://lkml.org/lkml/2014/9/18/305):
- rebased on top of the current linux-soc-thermal kernel

Best regards,
