I have a BF548 ezkit andI am using the latest trunk kernel/uboot/filesystem ( 2010R1 ).
How i can disable GPIO request for Push Buttons(PB1 PB2 PB3 PB4 on BF548) from uClinux kernel ?
Acquire these GPIO at early kernel boot up by your own code. Look GPIO PIN can't be marked P_UNDEF. So, you only choice is to acquire early by yourself.
