Re: [PATCH] leds-alix2: add support for button connected to J15

[Constantin Baranov]

Hi, Daniel!

I wonder why do you integrate the input driver into the leds driver. They
should be separated. Or at least the complex driver should be moved to the
"X86 Platform Specific Device Drivers" and renamed to some like "PC Engines
ALIX Extras". I personally would prefer the separation way.

Also ALIX.2 documentation describes the "Mode switch" driven by GPIO which is a
small button on front side of a board. I guessed your driver is not for this
button. If so, would it be better to provide the mode switch as KEY_PROG1 and
the J15 connected button as KEY_PROG2 at once?

Cheers,
Constantin
