X-Git-Tag: firefly_0821_release~3680^2~5013^2~65 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=1d56c453b14854637567c838109127b8decbf328;p=firefly-linux-kernel-4.4.55.git mmc: dw_mmc: set the card_width bit per card. This patch sets the card_width bit of CTYPE for the corresponding card. CTYPE[31] and CTYPE[16] correspond respectively to card[15] and card[0] for 8-bit mode. And CTYPE[15] and CTYPE[0] correspond respectively to card[15] and CTYPE[0] for 1-bit or 4-bit mode.
