Hi all,

as far as i understand, imx6sx can reach a HS200 mode (controller spec 4.5 max, so no HS400).

Btw, the ref. manual (68.1.1, Rev. 3, 06/2018) is saying:

- Card bus clock frequency up to 208 MHz

- Up to 832 Mbps of data transfer for MMC cards using 8 parallel data lines in
DDR(Dual Data Rate) mode 

I am miss somthing here, 200Mhz DDR means HS.400. 

Also, 832Mbps seems a max bandwidth of 100Mhz ddr, or, 200 SDR.

Any clarification is welcome.
