Yes, probably we'd better add another binding doc for it under Documentation/devicetree/bindings/arm/freescale/. And there's another fsl,aips-bus also has no binding doc, i'm not sure whether we need add a binding doc it as well. It seems already exist on many imx dts files. Shawn, your suggestion?

But in reality, some compatibles not used by kernel may be missing the documentation. You're welcomed to add them. Shawn

Add initial support for imx7ulp. Note that we need configure power mode to Partial Stop mode 3 with system/bus clock enabled first as the default enabled STOP mode will gate off system/bus clock when execute WFI in MX7ULP SoC. And there's still no MXC_CPU_IMX7ULP IDs read from register as ULP has no anatop as before. So we encode one with 0xff in reverse order in case new ones will be in the future.
