Buswidth is depeneded on Hardware schematic. Evne though host can support the 8bit buswidth, if hardware doesn't support 8bit mode, it doesn't work fine. So the buswidth mode selection leaves a matter in each SoC drivers. On the contrary to this, hardware supports 8bit mode, but host doesn't support it. then controller has to disable the MMC_MODE_8BIT. (Host can check whether 8bit mode is supported or not, since V3.0) Signed-off-by: Jaehoon Chung <jh80.chung@samsung.com> --- drivers/mmc/sdhci.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-)
