Felix Fietkau	6069bdd087	ramips: move mtk-mmc init to probe function to avoid breaking NAND flash ... The driver messes with the pin control settings - MMC and NAND are mutually exclusive Signed-off-by: Felix Fietkau <nbd@nbd.name>	2018-05-08 17:56:04 +02:00
NeilBrown	f27336e115	ramips: mtk-mmc: don't advertise highmem support. ... 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.

Felix Fietkau	6a621f4bd9	ramips: fix BUG_ON on mtk-mmc driver probe ... Our .dts files only have one device defined and this is unlikely to change, so statically initialize host->id to 0. Signed-off-by: Felix Fietkau <nbd@nbd.name>	2018-04-05 18:12:30 +02:00
