X-Git-Tag: v3.6-rc1~111^2^5~8
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4e0ee78f2af96676c9dca898c13250f62c513058;p=pandora-kernel.git

iommu: Add DMA window parser, of_get_dma_window()

This code was based on:
    "arch/microblaze/kernel/prom_parse.c"
    "arch/powerpc/kernel/prom_parse.c"

Can replace "of_parse_dma_window()" in the above. This supports
different formats flexibly. "prefix" can be configured if any. "busno"
and "index" are optionally specified. Set NULL and 0 if not used.
