dmaengine: export symbol of of_dma_request_slave_channel()
Current DMAEngine implementation of DT bindings can't support DT subnode. This patch export symbols of of_dma_request_slave_channel() for subnode DMA DT bingings. ex) rcar_sound: rcar_sound@ec500000 { ... rcar_sound,dvc { dvc0: dvc@0 { dmas = <&audma0 0xbc>; dma-names = "tx"; }; dvc1: dvc@1 { dmas = <&audma0 0xbe>; dma-names = "tx"; }; }; ... }; Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Acked-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
