From 988f831df398ff36f67b095245060c24c354e9e9 Mon Sep 17 00:00:00 2001 From: Nobuhiro Iwamatsu Date: Mon, 16 Mar 2009 03:22:07 +0000 Subject: sh: Move IRQ multi definition of DMAC to defconfig When SuperH CPU has IRQ multi of DMAC, SH_DMA_IRQ_MULTI becomes enable. The following CPU's are Multi IRQ of DMAC now. - SH775X and SH7091 - SH776X - SH7780 - SH7785 If SH_DMA_IRQ_MULTI becomes enable, dma-sh api driver is optimized for Multi IRQ.
