The i.MX6SL supports standard tuning as defined in standard host control spec v3.0. 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 1~3 add stardard tuning support for i.MX6SL. Patch 4~5 add DDR mode and delay line support Patch 6~8 some other related minor fixes. Tested on i.MX6SL EVK board.
