[PATCH 0/9] Enable pinctrl support for mach-mxs

[PATCH 0/9] Enable pinctrl support for mach-mxs

[Shawn Guo]

With pinctrl-mxs driver (DT only) applied on pinctrl tree, the mxs
device tree conversion can start basing on that support.  This series
adopts pinctrl support for mxs device drivers with a dummy pinctrl
state provided for non-DT boot, so that the pinctrl call in the device
drivers will be bypassed for non-DT probe while it starts working for
DT probe.

To ease the merge process, I would like to ask Arnd and Olof to pull
pinctrl tree as a dependency in arm-soc and have this series go through
arm-soc.

Regards,
Shawn

[PATCH 1/9] ARM: mxs: enable pinctrl dummy states

[Shawn Guo]

The mxs pinctrl driver will only support DT probe.  That said, the mxs
device drivers can only get pinctrl state from pinctrl subsystem when
the drivers get probed from device tree.

Before converting the whole mxs platform support over to device tree,
we need to enable pinctrl dummy states for those non-DT board files
to ensure the pinctrl API adopted by mxs device drivers will work for
both DT and non-DT probe.

Instead of calling pinctrl_provide_dummies() directly in every board
file, the patch introduces soc specific calls mx23_soc_init() and
mx28_soc_init() for boards' .init_machine hook to invoke, so that
any soc specific setup for non-DT boot only can be added there.

Hi,

Patch looks fine -- perhaps you could copy the explanation about the
dummy pinctrl state for non-DT boards from your series introduction
into this commit message, since the commit messages go into git and
the series description doesn't?  Thanks.

Yeah, I thought about doing that.  But after a second thought, I did
not do because I think device drivers should not care about these
underneath details.  Pinctrl subsystem and platform should just sort
these out and make them invisible to device drivers.
