Is this supported by mainline kernel and device tree?

This does not match device tree binding doc, which says:
- clock-names: should include entries "ckil", "osc", "ipp_di0" and "ipp_di1"

If it's compatible with "fsl,imx6q-uart", putting "fsl,imx21-uart" in
there is not going to help anything.

It's not helpful to have "fsl,imx6sx-usdhc" in there.
