[PATCH] gpio: only enable kona driver on BCM_MOBILE or for compile testing

[PATCH] gpio: only enable kona driver on BCM_MOBILE or for compile testing

[Uwe Kleine-König]

This change makes it easier to configure a kernel for a real machine by
not showing the option to enable it at all if COMPILE_TEST is off.

Hello,

I'm not sure if and how "Kona" fits into the bcm281xx namespace, but
reading through the commit logs of the changes touching
drivers/gpio/gpio-bcm-kona.c so far suggests it does. In this case I'd
consider it a good idea to mention "bcm281xx" in the help text of
GPIO_BCM_KONA.

Best regards
Uwe

Naming these components has been quite a challenge for our upstreaming
effort. Some things are not very obvious unless you know he chip or
were involved in those discussions.

"Kona" can be thought of as an architecture or a family of chips.
bcm281xx is one member of that family. There are others. I submitted
bcm21664 to arm-linux just a few minutes ago. bcm21664 also uses
gpio-bcm-kona.c.

Mentioning the SoCs in the help text is a good idea, but we'll likely
have to come up with a central location where all supported members of
the Kona family are listed, so they aren't scattered all over
different sub-systems (Kona watchdog, Kona GPIO, Kona timer, etc.) If
we don't have a central location, we'll be certain to forget updating
one of the help texts eventually, and it would become inconsistent.

Regards,
-Markus

Fine for me, but note that this was only a side node and is orthogonal
to the patch I sent. So if you want to ack it ...
