Many thanks for this driver. I have a couple of questions, one of which is 
more generic than specific to this driver.

When does a user need to use CP220X_DO_SHUTDOWN ? I cannot see any 
documentation about this define.

I see the driver has printf and being based on the cs8900 I am the source of 
this. Should we have these driver use printf or should they use printk now it 
exists ?
