From 0e95fb9ceb82433f4f910d1cece0f4d6b0c25c51 Mon Sep 17 00:00:00 2001 From: Robert Jarzmik Date: Tue, 11 Aug 2015 22:16:32 +0200 Subject: [PATCH] dmaengine: pxa_dma: don't use config direction parameter Don't use the direction passed in the configuration, and rely on each transfer's direction to prepare the transfers. This will enable future removal of direction parameter from dma_slave_config.
