Arasan controller supports AUTO CMD12, this patch adds "SDHCI_QUIRK_MULTIBLOCK_READ_ACMD12" quirk to enable auto cmd12 feature. By using auto cmd12 we can also avoid following error message "Got data interrupt even though no data operation in progress" Signed-off-by: Manish Narani <manish.narani@xilinx.com> --- drivers/mmc/host/sdhci-of-arasan.c | 1 + 1 file changed, 1 insertion(+)
