Subject[PATCH linux-next] edma: select arch common code to fix link
Date
EDMA code has been moved to a common folder with a new CONFIG_TI_PRIV_EDMA
switch. Select it when the edma driver is enabled.

This fixes the following link error:

drivers/built-in.o: In function `edma_remove':
of_iommu.c:(.text+0x4ef20): undefined reference to `edma_free_slot'

Hi,

Build of linux next-20130709 is broken for ARM multi_v7_defconfig. This patch
fixes it.

(Note: the error messages mentioning of_iommu.c are misleading.)

Best regards,

V.
