Subject: 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";
};
};
...
};
