I notice you left out the I2C driver and the MMC driver - given you 
had/have problems with them this is understandable. They can be sorted 
out later.

My main concern is that this file is named 'vt8500_defconfig', but it 
won't be able to cover all of the VT8500 'family'.
The earlier models (vt8500/wm8505) are ARM9, the WM8650 was ARM11, and 
then we got to the WM8750 that you are targetting (ARMv6) and finally 
the ARMv7 stuff (WM8850/WM8950).
I'm not particularly fussed about it (it's fine as is), but if you think 
of a better filename to fit the situation I wouldn't complain :)
