    ARM: samsung: make SAMSUNG_DMADEV optional · 27873b05

    The only remaining driver using the samsung dmadev code is the broken
    samsung-ac97 sound driver. However, as found by Russell's autobuilder,
    the elaborate dependency chains around it cause problems with
    circular dependencies.
    
    This is an attempt to simplify those dependencies by making the
    SAMSUNG_DMADEV option user-selectable. I also try to keep the
    default settings for all related options unchanged, so we don't
    introduce any regressions against earlier testing on linux-next.
    
    In particular, all s3c64xx and s5p* platforms keep selecting the
    pl330 and pl08x drivers they require, but the select statement
    is now moved towards the main platform option, and it remains
    optional by unselecting CONFIG_DMADEVICES.
