Hi everybody,
Here's a pretty large patch series that rework pin control and GPIO support
for SH and ARM SH/Renesas Mobile/Car platforms. The patches are based on top
of v3.7-rc6. You can get them from my git tree at
git://linuxtv.org/pinchartl/fbdev.git pinmux
The idea behind these patches is to move SoC-specific pin control code from
arch/ to drivers/pinctrl/ and use the Linux device model to instantiate the
pin control device. This is required to add device tree support for the pin
control device.
The code has been compile-tested on all modified platforms except SH7264 and
SH7269, and runtime tested on SH7372 (Mackerel), SH73A0 (KZM-A9-GT) and
R8A7740 (Armadillo) so far. I will runtime test it on R8A7779 (Marzen).
The SH7264 and SH7269 platforms have no gpiolib support so the PFC code can't
be compiled for them. As the currently implemented arch-level pinmux support
also depends on generic GPIO, we're moving from a situation where the code
isn't used to a different situation where the code isn't used. I don't
consider that as a regression.
Sorry for the numerous checkpatch warnings, patches that move code around or
rename files don't modify the content to make review easier, and thus carry
warnings from the existing code.
Currently missing from this series are DT bindings. I will send patches for
those a bit later. As they will build on top of this series I would appreciate
reviews (and hopefilly ack's).
