The original implementation select HS timing by default, add available
type selection for higher speed mode compatibility, such as hs200,
hs400, hs400es.
By the way, we assume that card run at 1.8V or 1.2V I/O when its timing
is ddr52/hs200/hs400(es).

Is there a cover letter for this series, please?
This patchset is used for hs200/hs400/ddr52 mode of eMMC device, and
fixes some bug for dw_mmc & sdhci controller.
It's only valid in U-Boot stage, we still use 'High Speed' in SPL.
I tested it on evb-rk3288 board(eMMC 4.5) and evb-rk3388 board(eMMC 5.0).
I just reviewed an MMC series at add higher speed support. I'm not
sure but I suspect these overlap.
Ha, I just reviewed Vignesh's patches, it focuses on uhs mode of sd
card. It looks to me.
But some details are not the same as mine. Anyway, what do you think?
Regards,
Simon
