- "arasan,sdhci-5.1": generic Arasan SDHCI 5.1 PHY
- "rockchip,rk3399-sdhci-5.1", "arasan,sdhci-5.1": rk3399 eMMC PHY
For this device it is strongly suggested to include arasan,soc-ctl-syscon.
- "xlnx,zynqmp-8.9a": ZynqMP SDHCI 8.9a PHY
For this device it is strongly suggested to include clock-output-names and
#clock-cells.

Note: This binding has been deprecated and moved to [5].

- xlnx,int-clock-stable-broken: when present, the controller always reports
that the internal clock is stable even when it is not.
- xlnx,mio-bank: When specified, this will indicate the MIO bank number in
which the command and data lines are configured. If not specified, driver
will assume this as 0.
