* gpio/langwell_gpio: ack the correct bit for langwell gpio interruptsMathias Nyman2011-07-08
| | | | | | | | | | | | | | | The wrong bit was masked when acking langwell gpio interrupts. Reason for maskig the wrong bit was probably because__ffs() and ffs() functions return bit indexes differently (0..31 vs 1..32) This fixes langwell based devices from hanging when a gpio interrupt is triggered and undoes the breakage which occurred in change set 732063b92bb727b27e61580ce278dddefe31c6ad Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

* gpio/omap4: Fix missing interrupts during device wakeup due to IOPAD.Ambresh K2011-06-16
| | | | | | | | | | | | | | | If gpio pins from bank[2-5] are marked as wakeup enable and if the wake is through gpio IO pad wakeup, then that wakeup gpio interrupt is lost. In the current implementation, GPIO driver stores the context of DATAIN of all the gpio in the bank. During GPIO resuming, it checks DATAIN with wakeup enabled pins of gpio bank. If there is status change, then manually toggle GPIO_LEVELDETECT to generate pseudo interrupt.
