Follow-ups
--- Barry Song 2010-06-03 05:47:58
The board has corrupted. I can't pull up the #CLATCH to high level with pull-up
res. The ad1939 will be in standalone mode and can't be controlled by cpu. but
ad1939 has same register layout and driver with ad1938. since it has worked
before, close it.
--- Sonic Zhang 2010-06-03 05:57:09
Because this driver is tested against ad1938 now without problem. Close this bug
against 1939.
