The power source just sounds like a power domain which doesn't need a shared driver, and shared elements in the design aren't really relevant if they're not visible in the usage of the device which given the very limited code sharing there seems to be in the driver doesn't seem to be the case here. --Nyl6UvCBOw4Y9nmf Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmGL0vkACgkQJNaLcl1U h9B9ggf+LhBJCEcQEiflSqmQWK6mee/XRX87kDJKZt7gA+iYGL6X7i252cT3Ky4L 3gfnLphDqNLlzexqLyZi3n2D0bv9YMfQJU84VM3mwXYHqmyzsLe9K0JuVqDWBl0D N/uN893B8ZQIAvXfDT2jMP1N2ZAuOaCBIxKkQ4SszMNj+Pk2IFNsFbcQ1OoxI7LS j8Wailql/PUeGLwLer0+8rYRZQHnstuxgnMF7UyIpPvrL9tW+5hDFgovugI4sOqc r0mLOIwsNtVs/2Y+H974EYhJyUZjO2NU3DgGywqd3oql3Ij7pdWlHVIahJfMDO/p haRzpeMQQVkGnLA5m2zyTTDpbgsH7Q== =gDAp -----END PGP SIGNATURE----- --Nyl6UvCBOw4Y9nmf--
