Currently there were two part of DMAC PL330 driver for support old styled s3c-pl330 which has been merged into drivers/dma/pl330.c driver. Actually, there is no reason to separate them now. Basically this patch merges arch/arm/common/pl330.c into drivers/dma/pl330.c driver and removes useless exported symbol, externed function and so on. The newer pl330 driver tested on SMDKV310 and SMDK4212 boards Cc: Jassi Brar <jassisinghbrar@gmail.com> Cc: Russell King <rmk+kernel@arm.linux.org.uk> Acked-by: Linus Walleij <linus.walleij@linaro.org> Acked-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Boojin Kim <boojin.kim@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com> Acked-by: Jassi Brar <jassisinghbrar@gmail.com> Signed-off-by: Vinod Koul <vinod.koul@linux.intel.com>
