Yeah, caps reg is wired to 0, but it can do high speed. Since we're VDD_330 only, I'm not sure the driver type flags do anything, but I'm still good with having consistency. Reviewed-by: Eric Anholt Interested in porting over the DMA support? :) I also noticed that the emmc wrapper module claims it can run with a clock from 50-100mhz, and the arasan says it can run at up to 50, 52, or 208mhz depending on SD/MMC mode. Could we get a boost from running the module at a higher clock rate? -------------- next part -------------- A non-text attachment was scrubbed...
