Subject: [PATCH 1/8] dma: coh901318: create a proper platform data file
From: Linus Walleij <linus.walleij@...aro.org>
This extracts the platform data that we will keep generic
from the U300 platform and associates it with the COH901318
driver in <linux/platform_data/dma-coh901318.h>.
Signed-off-by: Linus Walleij <linus.walleij@...aro.org>
