@SiewHoon this looks to me more of a feature request to support a specific hardware component more than a bug, and I don't have this particular hardware to test this. The best chance you have to resolve this is to port commits f30557401378b03986a5f4465c5d18ed6290f07a - 4c2752a88b82210c0b0ae5aff5c27128d0f62585 from the master branch and we will review and test the changes to ensure it doesn't break anything else.
