[PATCH v4 00/21] SH pinctrl DT support

[Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>]

Hello,

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

The patches are based on tags/renesas-next-20130513 from Simon's tree
(git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git), the R-Car
GPIO DT bindings proposal ("[RFC/PATCH v2 0/2] R-Car GPIO DT bindings") and the
marzen-reference ethernet patches ("[PATCH v2 0/4] marzen-reference ethernet
patches"). The result is available in my tree at

        git://linuxtv.org/pinchartl/fbdev.git pinmux/3.9/dt

The series is pretty self-explanatory. DT bindings are added in patch 02/21,
and the following 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.

Comments will be very appreciated on the DT bindings (02/21). Points I'm a bit
unsure about include:

- Should the driver support pin configuration subnodes as currently
  implemented, or should the subnodes be promoted to regular pin configuration
  nodes, with clients referencing multiple nodes ?
- Should the driver allow mixing function and configuration properties in a pin
  configuration node as currently implemented, or should it restrict the pin
  configuration nodes to either a function or one (or more) configuration(s) ?
- Should we specify common bindings for pinconf-generic instead of using
  Renesas-specific properties ? (If the answer to this question is yes, please
  help :-)).

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
