Listing two separate changes in one patch is a big indicator that it should be
split up into two patches. Also please be more verbose (aka explain more) what
patches do -

In the referenced commit I've also moved some init stuff around, which I'll
explain a bit more inline below.

Hi Max,
first of all, thanks for working on this :-)
I saw some general things inlined below, but I guess Wolfram is the better
person to check the i2c-specifics.

The register definitions are only used in the driver itself.
This also removes the last dependency on plat/ includes from the
i2c driver.

When pinctrl is not built the fallback functions fail silently
and emit either 0 error codes or NULL pinctrl handles.
Therefore it's needed to also check for this NULL-handle when
falling back to parsing the i2c gpios from devicetree.

Currently the fallback functions when pinctrl is not being built do
return either NULL or 0, either no pinctrl handle or no error,
making them fail silently.
All drivers using pinctrl do only test for error conditions, which
made for example the i2c-s3c2410 driver fail on a devicetree based

Hi,
while implementing devicetree support for the s3c2416 I noticed a fault
in the i2c-s3c2410 driver. The s3c2416 does not support pinctrl at the
moment (and will probably for a while), so the fallback functions in
pinctrl/consumer.h were used. These functions fail silently and the
relevant pinct

Hi,
I'm trying to find the best way on implementing an i80 interface (especially
the command mode) between a s3c2416 and an AUO-K1900 (epaper controller).
On the host side it is usable at least in all Samsung SoCs following the
S3C2443 and on the device side I've found, apart from the K1900, fo
