* timbgpio: add support for interrupt triggering on both flanksRichard Röjfors2010-03-061-9/+23
| | | | | | | | | | | | | Introduce support for triggering interrupts on both rising and falling edge. This feature requires version 3 or newer of the IP, a version check is done when triggering on both edges is requested.

* bitops: rename for_each_bit() to for_each_set_bit()Akinobu Mita2010-03-061-1/+1
| | | | | | | | | | | | | | | | | | | | Rename for_each_bit to for_each_set_bit in the kernel source tree. To permit for_each_clear_bit(), should that ever be added. The patch includes a macro to map the old for_each_bit() onto the new for_each_set_bit(). This is a (very) temporary thing to ease the migration.
