forked from mirror/openwrt
of_dma_configure() sets a default ->dma_mask of DMA_BIT_MASK(32), claiming devices can DMA from the full 32bit address space. The mtk-mmc driver does not support access to highmem pages, so it is really limited to the bottom 512M (actually 448M due to 64M of IO space). Setting ->dma_mask to NULL causes mmc_setup_queue() to fall-back to using BLK_BOUNCE_HIGH to tell the block layer to use a bounce-buffer for any highmem pages requiring IO.
