I've been wondering about suggesting the creation of a drivers/soc
directory. The idea would be for it to contain "system on chip" type
support code. I use that description loosely to fit any code which needs
to support drivers in multiple driver subsections.

An example use in my Zaurus tree is the TSC2101 which contains a
touchscreen, battery monitoring and sound. Handhelds.org has devices
such as the ASIC2/ASIC3 in the ipaqs (and other handhelds) which cover
many different drivers subsections.

Where practical, the sub drivers such as the touchscreen could be placed
into the specific driver areas such as drivers/input/touchscreen/ but
the core chip specific support would be in drivers/soc and the files
would be connected. 

Would that be acceptable in mainline?
