It looks like __clear_bit is #defined to generic_clear_bit which has
this declaration. generic_clear_bit(int nr, volatile unsigned long addr)
So maybe changing u32 to volatile unsigned long  will work?

Also it looks like dm365evm has the same logic for chip select.
At the least, it should also be fixed.  Since they look like copies, it
would be better if there was a common function.
