+ * DESCRIPTION: Execute an "orphan" _REG method that appears under an ACPI
* device. This is a _REG method that has no corresponding region
- * within the EC device scope. The orphan _REG method appears to
- * have been enabled by the description of the ECDT in the ACPI
- * specification: "The availability of the region space can be
- * detected by providing a _REG method object underneath the
- * Embedded Controller device."
- *
- * To quickly access the EC device, we use the ec_device_node used
- * during EC handler installation. Otherwise, we would need to
- * perform a time consuming namespace walk, executing _HID
- * methods to find the EC device.
+ * within the device's scope. ACPI tables depending on these
+ * "orphan" _REG methods have been seen for both EC and GPIO
+ * Operation Regions. Presumably the Windows ACPI implementation
+ * always calls the _REG method independent of the presence of
+ * an actual Operation Region with the correct address space ID.
