So this patch series add std tuning support for i.MX6SL. (NOTE i.MX6SL can also work on the old manual tuning mode as i.MX6Q/DL) In the meanwhile, it also adds DDR mode support. Then SD3.0 cards which can only support DDR50 can work properly now with this patch series. Patch 1~5 add stardard tuning support for i.MX6SL. Patch 6~7 add DDR mode and delay line support Patch 8~10 some other related minor fixes. Tested on i.MX6SL EVK board. The patch series is generated based on the latest mmc-next branch in Chris' tree.
