From 2f757f2ab7411cf0e2779012d8cda0cbf2f80d26 Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 8 Dec 2008 16:33:30 +0000 Subject: [ARM] dma: rejig DMA initialization Rather than having the central DMA multiplexer call the architecture specific DMA initialization function, have each architecture DMA initialization function use core_initcall(), and register each DMA channel separately with the multiplexer. This removes the array of dma structures in the central multiplexer, replacing it with an array of pointers instead; this is more flexible since it allows the drivers to wrap the DMA structure (eventually allowing us to transition non-ISA DMA drivers away.)
