Subject: Re: [PATCH v2 11/16] gpio: add support for the sl28cpld GPIO controller

Hi Michael,

this is looking good provided we can get the generic GPIO regmap
helper reviewed and merged. Thanks!

Apart from this depends it seems the patch is compile-time
independent of the other patches so I'd suggest we just merge
the generic regmap driver and this driver to the GPIO tree once
we feel finished with them, optimistically assuming that the MFD
driver will land and that we will not need any fundamental
changes in the GPIO driver.

Worst case we have to revert the driver and that is no disaster.

Yours,
Linus Walleij
