This series adds ufs driver support for ExynosAutov920,
ExynosAutov920 has the UFSHCI 3.1 compliant UFS controller.

ExynosAutov920 has a different mask of UFS sharability from ExynosAutov9,
so this series provide flexible parameter for the mask.

With this series applied, UFS is functional and basic I/O operations are
known to be working.

Changes since v1:
* collected Acked-by on patch 2/4
* This Acked-by from Krzysztof was long back, for now kept it
* rebased on linux-next
* fixed few self review comments
* split dtsi patch into two, separated out syscon node patch
