This could be caused by t
I am working with km v4l module (http://gatos.sf.net) and I have come
accross a strange issue with mach64 DMA engine. For some reason it would
not work unless I reset it using BUS_CNTL.
I.e.:
a=readl(kms->reg_aperture+MACH64_BUS_CNTL);
writel(a & (~(1<<6)), kms->reg_aperture+MACH6
