+Zevio GPIO controller

+Required properties:
+- compatible = "lsi,zevio-gpio"
+- reg = <BASEADDR SIZE>
+- #gpio-cells = <2>
+- gpio-controller;

+Optional:
+- #ngpios = <32>: Number of GPIOs. Defaults to 32 if absent

+Example:
+ gpio: gpio@90000000 {

+ reg = <0x90000000 0x1000>;

<tab> here and I can't see the reason to have this blank line here.

Doesn't look right.

Not sure how subsystem maintainer handle this but I would prefer
to keep this sorted as it is done in Makefile.
Yes, but without the gpio-zevio.c file the Kconfig item and the Makefile
entry wouldn't work and vice-versa. The three latest patches which added
GPIO
drivers weren't split as well.

ditto.
The patch contains several trailing whitespace reported by checkpatch.pl
which should be fixed.
Oh, I accidentially sent the uncleaned version of the patch, sorry.
I'll resend the cleaned version as V3.
Bye,
Fabian
