Can you be more explicit ? Is it the 'mpc8360' ? It is the 'chip'.


bindings/soc/fsl/cpm_qe/qe/par_io.txt was saying:

   - compatible : should be "fsl,<chip>-qe-pario-bank", 
"fsl,mpc8323-qe-pario-bank".

Which I first translated in yaml as :

   properties:
     compatible:
       items:
         - enum:
           - fsl,<chip>-qe-pario-bank
         - const: fsl,mpc8323-qe-pario-bank

But 'make dt_binding_check' complained about the < > around 'chip' so I 
removed them.

How should it be described ?

Thanks
Christophe
