Hi Bhanu,
Thank you for your patch.

The problem with this patchset continues being the same. You are using the trick of using a DT compatible string to instantiate an ACPI-only driver. You should have an ACPI ID for that device or use a DMI table to match the device and instantiate it (see for example the platform/chrome/cros_ec_lpc.c).
Thanks, Enric
