You should really contact someone who worked on the driver or Freescale about this - I don't think anyone on the CC list knows anything about the part. In general if you're asking about a specific driver this is a good approach. I've CCed Robin Gong who was the original author. --HHj6mHPeUinss9N+ Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBAgAGBQJUBw8dAAoJELSic+t+oim9RqIQAIxH5/Ee3sAAZHFwp3TsvdoM 0ocRbFMvdXIkJmToBPoo/GCLsCBgVFkOMNKEmeS+f7AKh5yF0zTkJQfydyK7B53u wibLQqQ7SKNMdsv7gZqqqCSal6Vf/VcHnLZIZ2iwtqLGUw2tato3g08vzGg42DkY d0bYqIg0pS5jKgqIgLHIcs/kEX0ZKF9+GY0dv6AVtQ1FVDtrbq0TMM8XVVWJ80mX iALR3AZYLk8xj8jBFIltikMpg5IjtmpU1mfG0HqjJlI4Ms7qgDWpzbwgdhdATVtx GhGkHX1WThIcKKNJiL9xg7zZaGdWgjiSARQJXgFe9yjTvdCB1sSbcB0xRlKxuPMO BXKjl+/bdmTZYkKemlrul7+V1EELCojM0ObcoT2w7XlAmFyTv3HbKHUxwq2qlCK0 55hmgz65DVmjq3aDyGCFod0VBnPJJZoEaqfWLc8m3Svz9QycxUl9WO+oSga/y+pl tZ2ozzS/f/csbkVStWDNn/Qyu0y28PAPGXqRF4jt4n1TdtZNl+KyOzfSU7W1Fb8B T1zZzi6cI+xXwx1Wof0BusJH/eo3o9Ob9Z+UzwDrOxQVuFlYU1h+OKo2vmd8+VhR QhrqtfLD+j10B5+TkLI1RW2dlRmxP9hLeUAWcD0MwCEu7L3HPDpSyuSxhv5ZrI3m qQjvH0h2NEBHZ3H4XiRV =/7pG -----END PGP SIGNATURE----- --HHj6mHPeUinss9N+--
