From 4e0ee78f2af96676c9dca898c13250f62c513058 Mon Sep 17 00:00:00 2001 From: Hiroshi Doyu Date: Mon, 25 Jun 2012 14:23:54 +0300 Subject: 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.
