Subject: [PATCH 2/8] DMA: shdma: add r8a7740 DMAC data to the device ID table
Date: Fri, 12 Jul 2013 15:43:52 +0200
Message-Id: <1373636638-18496-3-git-send-email-g.liakhovetski@gmx.de>

This configuration data will be re-used, when DMAC DT support is added to
r8a7740, DMAC platform data in setup-r8a7740.c will be removed.
