[PATCH v2 00/14] Marvell EBU thermal sensor consolidation

[Ezequiel Garcia]

Given Armada 370/XP and the other Marvell SoC with thermal support,
namely Kirkwood and Dove, have fairly similar thermal devices it
makes sense to integrate all of them into a single driver: mvebu-thermal.

The patches have been carefully splitted to make the changeset
as less invasive as possible. These changes can be divided in five stages:

 1. Rename 'kirkwood' driver to 'mvebu'
 2. Some fixes inherited from kirkwood driver applied to new mvebu driver
 3. Prepare mvebu driver to support multiple SoC
 4. Add thermal support for each Marvell SoC on top of mvebu driver
 5. Add device tree nodes for Armada 370 and Armada XP
 6. Fix defconfigs for all the platforms involved

Testing have been done on the following boards:

Kirkwood:   Plat'home Openblocks A6
Armada 370: Globalscale Mirabox and Marvell Armada 370 RD
Armada XP:  Plat'home Openblocks AX3 and Marvell Armada XP DB-MV784MP-GP

Dove is *not* tested due to lack of hardware.

Also, please note that the defconfigs for involved platforms have been fixed
deliberately in a single patch, to ease maintainer's job as the defconfigs
file goes through one tree and the thermal driver should go through another.

Since I'm merging two existing drivers into a new driver, I retained authorship
and copyright of the merged drivers and added my own. For this reason, I'd like
to have Andrew and Nobuhiro Acked (or Nacked, of course).

This series is based in v3.9-rc2 with the following patches applied:

  Dove: Thermal: Add DT node and enable in defconfig
  ARM: Kirkwood: Add support thermal sensor for 88F6282 and 88F6283

Also it depends on the following fixes that I recently sent for v3.9:

  thermal: dove: Fix thermal sensor formula
  thermal: kirkwood: Fix thermal sensor formula
  thermal: mvebu: Fix valid check for thermal register

To make testing easier I've pushed a github branch:

  https://github.com/MISL-EBU-System-SW/mainline-public/commits/mvebu-thermal-v2

Changes from v1:

  * Fixed devm_ioremap_resource() API usage, as pointed out by Andrew,
    Rusell and Sergei.

  * The fixes that corresponded to be applied on v3.9 were removed
    from this patchset and sent as independent patches, as requested
    by Jason Cooper.

  * The formulas for thermal sensor were replaced by better ones,
    confirmed by Lior Amsalem.

  * The infrastructure for multiple SoC was reworked to drop switches,
    using function pointers instead as suggested by Jason Gunthorpe.

Any feedback or comments are welcome!
