It's mentioned
"DON’T use wildcards or device-family names in compatible strings."

https://www.kernel.org/doc/html/latest/devicetree/bindings/writing-bindings.html

Here, in sam9x7x, the first "x" is part of name itself and not a 
wildcard, so can I just stick to sam9x7?

we have previously followed the same in many bindings
"$ grep -nri sam9x7 Documentation/devicetree/bindings/"
