We use CPLD to emulate gpio pca9506 I/O expander on each server
boards.
Therefore, add pca9506 to probe driver for the CPLD I/O expander.

I think it might be best if you add your own compatible to the list in
the gpio-pca95xx binding just in case there are some behavioural quirks
of your CPLD implementation? Not sure if this should be
"facebook,pca9506" or "wywinn,pca9506", but assuming facebook, from
there you can specify

    compatible = "facebook,pca9506", "nxp,pca9506";

This allows you to add the quirks to the driver as required in the
future through the more-specific compatible.

Hi Andrew,

Thanks for the review.
I'll add the "facebook,pca9506" in gpio-pca95xx binding in next version of patches.

Hi Andrew,

I tried to add "facebook,pca9506" in the compatible list of gpio-pca95xx binding
and add compatible = "facebook,pca9506", "nxp,pca9506" but got following failed
messages:
    gpio@21: compatible: 'oneOf' conditional failed, one must be fixed:
        ['facebook,pca9506', 'nxp,pca9506'] is too long
        'diodes,pi4ioe5v6534q' was expected
        'nxp,pcal6534' was expected
        from schema $id: http://devicetree.org/schemas/gpio/gpio-pca95xx.yaml#
Would like to ask do you have any suggestions? Thanks.

Mmm, maybe it's best if we leave the compatible as just 'nxp,pca9506'
for now, but if you do discover quirks then we can consider this again.
