Here is what we have in existing DTS upstream:

arch/powerpc/boot/dts/fsl/mpc8569mds.dts- 
compatible = "fsl,mpc8569-qe-pario-bank",
arch/powerpc/boot/dts/fsl/mpc8569mds.dts: 
             "fsl,mpc8323-qe-pario-bank";
--
arch/powerpc/boot/dts/fsl/mpc8569mds.dts- 
compatible = "fsl,mpc8569-qe-pario-bank",
arch/powerpc/boot/dts/fsl/mpc8569mds.dts: 
             "fsl,mpc8323-qe-pario-bank";
--
arch/powerpc/boot/dts/kmeter1.dts- 
compatible = "fsl,mpc8360-qe-pario-bank",
arch/powerpc/boot/dts/kmeter1.dts: 
     "fsl,mpc8323-qe-pario-bank";
--
arch/powerpc/boot/dts/mpc832x_rdb.dts: 
compatible = "fsl,mpc8323-qe-pario-bank";
--
arch/powerpc/boot/dts/mpc836x_rdk.dts-                  compatible = 
"fsl,mpc8360-qe-pario-bank",
arch/powerpc/boot/dts/mpc836x_rdk.dts: 
"fsl,mpc8323-qe-pario-bank";
--
arch/powerpc/boot/dts/mpc836x_rdk.dts-                  compatible = 
"fsl,mpc8360-qe-pario-bank",
arch/powerpc/boot/dts/mpc836x_rdk.dts: 
"fsl,mpc8323-qe-pario-bank";

If the problem in the DT schema is the fsl,chip-qe-pario-bank, should I 
replace it with the two possible compatible we have in existing DTS, ie 
"fsl,mpc8569-qe-pario-bank" and "fsl,mpc8360-qe-pario-bank", or should I 
just ignore them are they are useless for the drivers, or else ?

Thanks
