The PCA962x family shares the same I2C register layout and functionality.
This adds support for the following chips:
PCA9623 4-channel
PCA9624 8-channel
PCA9622 16-channel
PCA9626 24-channel
Tested only the PCA9624. Other devices based on datasheet information.

Just a gentle "ping", haven't seen any feedback for quite some time. Any
issues, comments?
