commit 15ca3dafb2662db4d9a5aca5f022497395436503
Author: Werner Almesberger <werner at openmoko.org>

    Increase camera IO drive strength from 2 mA to 8 mA
    
    The camera driver reduced all IO drivers from their reset defaults of
    6 mA to only 2 mA, which caused severe signal distortion at higher
    speeds. This patch sets them to 8 mA and also removes apparently
    useless repetitions of the setting.
    
    Note that the correct setting of the I2C pullups still needs to be
    verified.
