Hi Balaji, I found a little fun non-problem today: we often set GPIO2CFG and GPOCFG to 1 when we want to output a "1", but we should actually set it to 7 alias PCF50633_GPOCFG_GPOSEL_1.
This doesn't seem to cause any actual trouble, but then, you never know. By the way, when tracking down such things, you may find this script useful: http://svn.openmoko.org/developers/werner/bin/gg It uses git-grep to find all occurrences of the search expression, displays them, and then launches vi to edit/view the files, with vi searching for the same expression. Usage e.g., gg pcf50633_gpio_set - Werner
