Following on from the discussion we had here and a bit off offline discussion with Stephen it seems that we need to drop this since having it in the DT as a separate regulator doesn't really represent the hardware. The SAW is controlling the underlying PMIC regulator and we will eventually need to control that regulator directly so the SAW should be presented as an alternative control interface for the PMIC regulator. --HzaOE8X7KzPzAQEl Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJWxz2hAAoJECTWi3JdVIfQYKoH+wX9rMoZG5m2SFKaWKvn5zJY OSGIiyvOEXeWLhi7P3IYOTcERpLWm1kgBUclWz1J2wd7lmGD1kjxtKpJxNUUbu9D TW1lhm0dgO2JJ9ZKDZjtazRmywuYnb7JdJpm4szJV5OwZMgMYmd2GCR8F2fQ9Nkk 1gHtdvguAyvX9tB3KyZ7wBm7nqNCMX7LBLdLSpJWcMrYjmQVHaV7JbQjAyroX/uv wp9jQMtKoSkvI5opEUu4OpTypYjP7PTUHQoAm8OSSKkc5NuNJq6EMmcPtsUfOJFO 0slVJKY9WDgK1pW9rit2R9dE4fVkeV6OQHohNjA8v2JNwjJQLaxXMBFWNZg6hOk= =EuwZ -----END PGP SIGNATURE----- --HzaOE8X7KzPzAQEl--
