[PATCH v7 00/19] SH Mobile pinctrl DT support

[PATCH v7 00/19] SH Mobile pinctrl DT support

[Laurent Pinchart]

Hello,

Here's the seventh version of the SH Mobile pin controllers (PFC) DT support
patch set.

The patches depend on the v3.11-rc pinctrl core. Linus Torvald has merged the
pinctrl tree into his master branch, so I've based this series on a merge of
Linus' master and tags/renesas-next-20130704v3 from Simon's tree
(git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git). The result
is available in my tree at

        git://linuxtv.org/pinchartl/fbdev.git pinmux/3.11/dt

The series is pretty self-explanatory. The patches gradually move SoC code
and board code over to the device tree for the armadilla800eva-reference,
kzm9g-reference and marzen-reference boards. The code has been tested on the
three boards, but armadillo800eva has received less testing as it can't be
booted all the way to userspace with network support due to missing DT
bindings.

As the patches only touch the SH Mobile architecture they can all be merged
through Simon's tree. Simon, will you rebase your tree on v3.11-rc1 when it
will be tagged ?

Changes since v6:

- Dropped the sh-pfc driver patches that have been merged in mainline
- Added kzm9g-reference patches back now that pinconf DT bindings are
  available

Changes since v5:

- Dropped generic pinconf support
- Dropped kzm9g-reference patches, as those require pinconf support

Changes since v4:

- Added generic pinconf bindings
- Use symbolic names for GPIO flags

Changes since v3:

- Fixed the GPIO flags description in the DT bindings documentation
- Mention the gpio-rcar driver in the DT bindings documentation for platforms
  that use it
- Removed unneeded #ifdef CONFIG_OF...#endif
- Removed unused support for platform data
- Simplified error path in sh_pfc_dt_node_to_map()
- Added gpio-ranges for r8a7778, r8a7779 and r8a7790

Changes since v2:

- Added pin configuration properties
- Rewrote all arch changes

Changes since v1:

- Fixed gpio cell number 2 documentation
- Added missing gpio-controller and #gpio-cells properties to r8a7740 DT
- Split kzm9g DT patch into SoC and board patches
- Dropped pinctrl mappings move to DT

In general I like to rebase once the renesas code that was accepted into
the arm-soc tree has been accepted into Linus's tree.

It appears that is already the case, except for some late fixes
(renesas-fixes2-for-v3.11), as of the current (pre v3.11-rc1) master branch
of Linus's tree. So yes, I plan to rebase once v3.11-rc1 is tagged.

I have now rebased.  Accordingly, this series is now queued up for v3.12 in
the pinmux branch. That branch is based directly on  v3.11-rc1. This
is available in renesas-devel-20130716.
