You can do something like this

static u64 dwc3_exynos_dma_mask = DMA_BIT_MASK(32);

static int dwc3_exynos_set_dmamask(struct device *dev, void *c)
{
	dev->dma_mask = &dwc3_exynos_dma_mask;

	return 0;
}

And in your probe after of_platform_populate, you can add

device_for_each_child(&pdev->dev, NULL, dwc3_exynos_set_dmamask);

Here pdev is the platform device of dwc3-exynos. By this way all the 
children of dwc3-exynos will have dma_mask set to the required value.

I'm not sure if there is any other better way to achieve the same 
(without patching of.c ;-))

Thanks
Kishon

should be fine, but we can wait a bit to see if DeviceTree folks reply,
your patch will only go on v3.10 anyway.
