Yes, that's one concern of mine... I already can imagine someone suggesting adding conditionals to the power sequence data. Perhaps also direct memory read/writes so you can twiddle registers directly. And so on. Where's the limit what it should contain? Can we soon write full drivers with the DT data? =3D) Tomi --=-Z7zQN41Yy4VWSEps7HLu Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJQUYMRAAoJEPo9qoy8lh71/G0QAK/iACEID25N+9nv22F94xd8 XJaD08QNPvPVBn6i2ImESx9GyIC0MW38txdKcNLWsoEmxiTTUiHZt9ORH5uihGMZ 0etZRUzuFZKgYLXfpMR57Np+23j55w51vYYjBsmrRooDsWxdcXO6CDTJQEzVctya SJg4LjH/HznrwMsSbtFsmWEO2RIO9ukM4kHqTCRgYOdVfmRP8il/rpMyTBCneZ2y qfEHkWIUtwmdDuzOj45c8G0apugUmb0eBGai5xc7PkXng5zfveZZNiBSlt4Z+CQ5 C9+PElyF+6NOEtHV1J0OCz3njOJnGGUjqPpoaP5SSSRKtqdzh5ypmM59O9SWHx08 AIaWBZkbctf21EWyRoLsXKckn2JC9NUR7qCNyOTLbH5wPwXdhA5o6wehuZMOTNk/ AsGpl0W/fL+sxZ9OerIYCZhiLpIO28pA9X1TuUOEsPqFjod1CCgKVrm+xwephZn1 VuRFOAYTYf/OYo2ahcSxZ9+s3q3vkCQMsiqdtFK7TaLE7YdTPDGQBKHfEzSICIeQ DLvmaldw9MuhwsxF+HAtzdIUlzwtJ2UfIcFNoHY57iYCf8lrfbV2DdwL4f/FCk43 lhEeZryEkqDhnLCEw8LdjkxDY+o+8lcm1uY6YhG6dNtFpeMbbHR24p8SNtAZ0lZu exN3o8jW2fuTRlnisslK =deQn -----END PGP SIGNATURE----- --=-Z7zQN41Yy4VWSEps7HLu--
