Hi Andy
Sorry for the late reply

The reason for writing this driver is that our customers hope that the LED and GPIO can be used out of the box
When they using our X86-Platform

About the document and ACPI expert, I will provide them after I improve them. Please wait for a few days.

Thank you very much

    NAK as per v2.

    Please, add a proper documentation and show ACPI excerpt, and last but
    not least is missing justification.
