linux-toradex.git/include/asm-sh/dmabrg.h, branch v2.6.25.12 Linux kernel for Apalis and Colibri modules sh: SH7760 DMABRG support. 2007-05-09T08:36:15+00:00 Manuel Lauss mano@roarinelk.homelinux.net 2007-05-09T08:36:15+00:00 fc467a2623029976899261d6d379779c950ddcba The DMABRG is a special DMA unit within the SH7760 which does data transfers from main memory to Audio units and USB shared memory. It has 3 IRQ lines which generate 10 events, which have to be masked unmasked and acked in a single 32bit register. It works independently from the tradition SH DMAC, but blocks usage of DMAC channel 0. This patch adds 2 functions to associate callbacks with DMABRG events and initialization.
