Let's be consistent and use uppercase only, for both macro and defines.

24f4f2eef2 mfd: use dev_* macros for asic3 debugging 
We replace the various printks, and use the dev_* macros instead.

3b26bf1722 mfd: New asic3 gpio configuration code 
The ASIC3 GPIO configuration code is a bit obscure and hardly readable.
This patch changes it so that it is now more readable and understandable,
by being more explicit.

1effe5bc6c mfd: asic3 children platform data removal 
Platform devices should be dynamically allocated, and each supported
device should have its own platform data.
For now we just remove this buggy code.

6f2384c4bd mfd: asic3 gpiolib support 
ASIC3 is, among other things, a GPIO extender. We should thus have it
supporting the current gpiolib API.

fa9ff4b185 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.
