Subject: [RFC] [PATCH -mm] ASIC3 driver
Hi,
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.
