I'm excited to see this patch posted. As I understand it, this
"separate polling gpio button driver" approach is preferred to the
"polling extensions in gpio-keys approach". I'm sorry I missed the RFC
[1] : I posted a revised version of Alex Clouter's and Paul Mundt's
polling gpio-keys support [2]. But now I can try integrating this
driver. :)
I will be posting a version of the patch shortly that is still using
the polling-gpio-keys support -- because there are discussions in the
machine-specific parts. Then I will try to integrate this driver into
the series.
Best Regards,
Ben Gardiner
