Here is a series adding HS200 support to the SDHI driver. Building the actual functionality on top of SDR104 support was rather easy. However, I figured the checks for enabling tuning were rather scattered over the driver and could be further improved. So I did some refactoring of that to make adding HS200 support then a one-liner :) This has been tested on Salvator-X boards with R-Car H3 and M3-W SoCs. It has also been tested on a Lager board (R-Car H2) checking SDR50/104 for regressions. The whole test document showing significant speed-ups reading from the on-board eMMC can be found here: http://elinux.org/Tests:eMMC-HS and the branch can be found here: git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/topic/sdhi-emmc-hs Please comment, review, apply...
