I mean there is already dev->dev.coherent_dma_mask = DMA_BIT_MASK(32); at function of_platform_device_create, why can't add dev->dev.dma_mask = &dev->dev.coherent_dma_mask after that? If DT core can do above things, can we delete dma_mask assignment at every driver? -- BR, Peter Chen -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
