Hi all, Linux 5.10-rc1 switched from having a single dma offset in struct device to a set of DMA ranges, and introduced a new helper to set them, dma_direct_set_offset. This in fact surfaced that a bunch of drivers that violate our layering and set the offset from drivers, which meant we had to reluctantly export the symbol to set up the DMA range. The drivers are: drivers/gpu/drm/sun4i/sun4i_backend.c This just use dma_direct_set_offset as a fallback. Is there any good reason to not just kill off the fallback? drivers/media/platform/sunxi/sun4i-csi/sun4i_csi.c Same as above. drivers/media/platform/sunxi/sun6i-csi/sun6i_csi.c This driver unconditionally sets the offset. Why can't we do this in the device tree? drivers/staging/media/sunxi/cedrus/cedrus_hw.c Same as above. _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
