After Matt discuss with Sean_C, the key that makes INT works as expect
is the CTS state. If the CTS and RTS on S3C2442 side state was correct,
then the receiving call with interrupt will happen. If the CTS state not
correct, will cause GSM think the state was not correct. So, the
firmware wake part seems ok.
The GSM wake mechanism described in the old bugzilla entry:
Now Matt are looking into the GSM suspend(sleep) current too high issue,
this might be firmware configuration or we do something on the Samsung
CTS/RTS behavior side.
