From 9b233f9b2e927a93b3dc8b8e9c1d59f79be13dcc Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Wed, 15 May 2013 10:51:26 +0100 Subject: [PATCH] dmaengine: ste_dma40: Don't configure runtime configurable setup during allocate Using the dmaengine API for slave transfers, allocating and configuring a channel are two separate actions. Here we're removing logical channel configuration from the channel allocation routine for slave transfers, as the same config is already done in the runtime config function, and put the corresponding call into d40_config_memcpy() for the memcpy code path.
