accel: clapper: glimmer: Add support for accelerometer interrupt.stabilize-5696.B
Adding in support for accelerometer interrupt for use currently
in clapper and glimmer. This is disabled by default and can
be enabled with CONFIG_ACCEL_INTERRUPTS.
BUG=none
BRANCH=rambi
TEST=Manual test on a glimmer using accelint console command.
On console enter:
accelint 0 32
When you tap the lid, it should fire the interrupt and print msg
to console.
accelint 1 32
Tap the base and it will fire another interrupt.
