Subject: How about the MMC/SDIO host controller standard under Linux ?

HI

I see the drivers/mmc/host/sdhci.h define the common register as
describe within
Part_A2_SD_Host_Controller_Simplified_Specification_Ver3.00_Final_110225.pdf
In this case all command related access register is common .(sdhci-xxx.c)
Does this mean all sdhci-xxx.c that will support SD host controller  standard ?

I see most code  such as s3cmci.c ,msm_sdcc.c that has their only
private register that access by such as mmc_host_ops->request function
.
I want to know whether this mean these host controller doesn't support
 SD host controller standard ?

Best Regards .
