Submitting V7 version with all comments fixed. Most of the patches are acked by
Eduardo. All the un-acked patches are modified according to the review comments.
If any comments please let me know.
Thanks,
Amit Daniel
Changes in V7:
* Fixed all the coding guidelines comments given by Eduardo.
* Moved the request irq call below the core thermal registration as per discussion
with Eduardo.
* Appropriate logs/TODO's/comments added for some review comments which are still
same as before,
1) calibration register setting still uses enums.
2) very few soc check's still left in the driver.
3) Cooling devices stored in an array in the exynos core thermal layer.
Changes in V6:
* Uses ARCH_HAS_BANDGAP config flag which is merged now in arm tree.
(http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=7758/1).
* In this version patches 1, 2, 3, 4 and 30 are modified. Others are same as V5.
* Added acked by from Jonghwa Lee.
* Rebased against Thermal Maintainer next tree.
Changes in V5:
* Most of the changes in this version is as per suggestion from Jonghwa Lee. I
have retained one to one mapping of platform data with TMU instances as the
TMU's are different devices. In exynos5440 soc there is some register
sharing across multiple TMU's but in exynos5420 there is no register between
multiple TMU's, so the current implementation is useful to support both of the
above.
This patch uses localized ARCH_HAS_TMU Kconfig option and is a temporary solution
until a more generic macro ARCH_HAS_BANDGAP is introduced as per discussion in
the link https://patchwork.kernel.org/patch/2659001/.
* trip type is passed as platform data.
* HW trip is allowed only for maximum level.
* Platform data structure is now abstracted inside 1 more structure to support
multiple sensor TMU data.
Changes in V4:
Almost all the changes in this version is as per suggestion from Eduardo.The
major ones are listed below,
* Added kconfig symbol ARCH_HAS_TMU which needs to be enabled by platform. With
this change existing symbol EXYNOS_TMU_DATA is not needed.
* Movement of freq_clip_table from exynos_tmu.h to exynos_thermal_common.h is
explained in the commit logs.
* Wrote all register description documentation.
* Split 5440 TMU support patch into controller change, configuration data and
feature addition patches.
* Remove all *LINUX_* in the header files.
* Still regulator enable is kept optional but a TODO: comment is added to fix
it later.
Changes in V3:
* Added proper dependency of different exynos thermal Kconfig symbols. Basically 3
Kconfig can be enabled now and corresponds to tmu driver. exynos common part
and exynos configuration data. This issue was raised by Rui Zhang.
Changes in V2:
* Separated SOC data from TMU driver. This is as per suggestion from Eduardo.
* Merged the new file created for exynos5440 TMU controller with the existing
TMU controller code.
* Removed the DT parsing code as now the SOC specific data are cleanly put
inside the data specific file.
* Even the register definations/bitfields are treated as data as there is
some variation across SOC's.
This patchset adds TMU(Thermal management Unit) driver support for
exynos5440 platform. There are 3 instances of the TMU controllers so
necessary cleanup/re-structure is done to handle multiple thermal zone.
Patch (exynos4: Add documentation for Exynos SoC thermal bindings) from
Lukasz Majewski is already posted to mainline. Using it as it is needed.
(http://www.mail-archive.com/linux-samsung-soc@xxxxxxxxxxxxxxx/msg17817.html)
Patch (thermal: exynos: Support thermal tripping ) from Jonghwan Choi is
added here with some changes.
(https://patchwork.kernel.org/patch/1668371/)
Patch (thermal: exynos: Support for TMU regulator defined at device tree)
is a repost of my earlier patch(https://patchwork-mail1.kernel.org/patch/2510771/)
and adds regulator support.
Patch (ARM: dts: Add device tree node for exynos5440 TMU controller) and
patch (arm: exynos: enable ARCH_HAS_BANDGAP) can be merged through exynos platform
maintainer as this can cause merge conflict.
All these patches are based on thermal maintainers git tree,
git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux.git next.

Hi Eduardo,
I think, Amit almost addressed comments from you guys, there are several
comments though. And it can be fixed during -rc ;-)
So please consider pick this series in your tmu tree. If any concerns,
please kindly let me know.
Note, if any merge conflicts with Samsung DT files, let me check.
Thanks,
- Kukjin
