42 * Device 103C89C6 does have _DSD, however it is setup to use the wrong boost type.
43 * We can override the _DSD to correct the boost type here.
44 * Since this laptop has valid ACPI, we do not need to handle cs-gpios, since that already exists
45 * in the ACPI. The Reset GPIO is also valid, so we can use the Reset defined in _DSD.
