From 538528de0cb256f65716ab2e9613d9e920f97fe2 Mon Sep 17 00:00:00 2001 From: Jarkko Nikula Date: Wed, 13 Feb 2008 11:47:29 +0200 Subject: [PATCH] ARM: OMAP: Pass logical DMA channel number always to callback handlers This makes parameter passing to DMA handlers uniform between non-chained and chained transfers and makes debugging easier. Additional data like chain_id can be always passed to handlers via callback data if needed.
