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 Tony Lindgren (3): Input: omap4-keypad - configure interrupt as level Input: omap4-keypad - disable unused long interrupts Input: omap4-keypad - check state again for lost key-up interrupts drivers/input/keyboard/omap4-keypad.c | 64 ++++++++++++++++++++++----- 1 file changed, 54 insertions(+), 10 deletions(-)
