[PATCH] dmaengine: rcar-hpbdma: tidyup residue_granularity

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>

The driver doesn't support residue reporting at all.
residue_granularity should be set to DMA_RESIDUE_GRANULARITY_DESCRIPTOR.
Special thanks to Laurent
