Subject: dma: pl330: Set residue_granularity
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bfb9bb42d60d7cf1d8057c7c3978dcc53c4d25fd;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

dma: pl330: Set residue_granularity

The pl330 driver currently does not support residue reporting, so set the
residue granularity to DMA_RESIDUE_GRANULARITY_DESCRIPTOR.
