[PATCH v3 0/8] thermal: exynos: various cleanups

[Bartlomiej Zolnierkiewicz]

Hi,

This patch series contains various cleanups for EXYNOS thermal
driver.  Overall it decreases driver's LOC by 9%.  It is based
on next-20140731 kernel.  It should not cause any functionality
changes.

Changes since v2 (https://lkml.org/lkml/2014/6/17/436):
- synced patches against next-20140731
- dropped patch "thermal: exynos: remove dead code for
  TYPE_TWO_POINT_TRIMMING calibration" (newly added Exynos3250
  SoC support uses TYPE_TWO_POINT_TRIMMING calibration)
- updated patch description for patch #2
- dropped Reviewed-by from Amit from patch #8 (due to changed
  scope of the patch)

Changes since v1 (https://lkml.org/lkml/2014/5/5/194):
- synced patches against next-20140617
- merged patch "thermal: exynos: remove unused defines" into
  "thermal: exynos: remove unused struct exynos_tmu_registers
  entries" one (per request from Eduardo)
- improved patch descriptions for patches #1-5
- fixed documentation for pdata->gain and pdata->reference_voltage
- added Reviewed-by from Amit to patches #6, #7 and #10
- added missing Acked-by from Kyungmin Park

Best regards,

[PATCH v3 1/8] thermal: exynos: remove unused struct exynos_tmu_registers entries

[Bartlomiej Zolnierkiewicz]

Remove unused / write-only entries from struct exynos_tmu_registers.
Then remove unused defines while at it.

We don't keep the unused/untested features in the kernel just
in case that some future hardware might need it.  Such code has
a real maintainance cost (all other code changes have to take
the dead code into account) and usually makes future changes
more difficult, not easier (i.e. recent additions of Exynos5420
SoC and Exynos5260 SoC thermal support has not made use of any
of the driver's currently unused/untested features, moreover
the recently added code is more complex than needed because of
the existing dead code).  Also all removed dead code is still
accessible in the kernel git repository and can be easily
brought back if/when needed.

There should be no functional changes caused by this patch.

[PATCH v3 2/8] thermal: exynos: remove dead code for HW_MODE calibration

[Bartlomiej Zolnierkiewicz]

The commit 1928457 ("thermal: exynos: Add hardware mode thermal
calibration support") has added HW_MODE feature but it has never
been enabled.  As such it has been a dead code for over a year
now and should be removed from the kernel.

We don't keep the unused/untested features in the kernel just
in case that some future hardware might need it.  Such code has
a real maintainance cost (all other code changes have to take
the dead code into account) and usually makes future changes
more difficult, not easier (i.e. recent additions of Exynos5420
SoC and Exynos5260 SoC thermal support has not made use of any
of the driver's currently unused/untested features, moreover
the recently added code is more complex than needed because of
the existing dead code).  Also all removed dead code is still
accessible in the kernel git repository and can be easily
brought back if/when needed.

There should be no functional changes caused by this patch.

[PATCH v3 3/8] thermal: exynos: remove redundant pdata checks from exynos_tmu_initialize()

[Bartlomiej Zolnierkiewicz]

Remove runtime checks for pdata sanity from exynos_tmu_initialize().

The current values hardcoded in pdata will never trigger the checks
and checking itself is not proper.  The checks in question are done
at runtime in a production code for data that is hardcoded inside
driver during development time and later it doesn't change.  Such
data should be verified during development and review time (i.e. by
a script parsing relevant data from exynos_tmu_data.c, one can also
argue that verification to be done is so simple that the review by
a maintainer should be enough).

There should be no functional changes caused by this patch.

[PATCH v3 5/8] thermal: exynos: simplify temp_to_code() and code_to_temp()

[Bartlomiej Zolnierkiewicz]

* Remove dead temp check from temp_to_code() (this function users
  in exynos_tmu_initialize() always pass correct temperatures and
  exynos_tmu_set_emulation() returns early for EXYNOS4210 because
  TMU_SUPPORT_EMULATION flag is not set on this SoC).

* Move temp_code check from code_to_temp() to exynos_tmu_read()
  (code_to_temp() only user).

There should be no functional changes caused by this patch.
