From 8185e51f358a8dd4801b67e8c66f03eb9eeaba75 Mon Sep 17 00:00:00 2001 From: Chris Brandt Date: Mon, 12 Sep 2016 10:15:06 -0400 Subject: mmc: tmio-mmc: add support for 32bit data port For the r7s72100 SOC, the DATA_PORT register was changed to 32-bits wide. Therefore a new flag has been created that will allow 32-bit reads/writes to the DATA_PORT register instead of 16-bit (because 16-bits accesses are not supported).
