ASIC3 driver
This is a patch for the Compaq ASIC3 multi function chip, found in many PDAs (iPAQs, HTCs...). It is a simplified version of Paul Sokolovsky's first proposal [1]. With this code, it is basically a GPIO and IRQ expander. My plan is to add more features once this patch gets reviewed and accepted.
