[PATCH v2 0/3] mmc: sdhci-of-k1: add reset support

[Yixun Lan]

This series try to add reset support explicitly to SpacemiT SDHCI controller.
Previous it works well for eMMC due to it's already initialized at brom or
bootloader phase.
  The controller has two reset lines, one connect to AXI bus which shared by
all controllers, while another one connect to individual controller separately.
