Subject: [PATCHv2 0/3] Lost key-up interrupt handling for omap4-keypad

Hi all,

This series updates omap4-keypad to configure the interrupt level and
disables unused long interrupts. And then it implements the missing parts
for the lost key-up interrupt quirk as described in the silicon errata pdf.

I can still reproduce one issue where a fast shift-shift-j can produce an
upper case J instead of j for example. This seems unrelated to the controller
idling with state issue probably, maybe it's some debouncing related issue.
So far playing with the debouncing configuration has not helped with this
issue though. Anyways, please test if you're seeing stuck keys on droid4.

Regards,

Tony
