GTA02 vibrator uses FIQ-based PWM, so that's not needed for GTA02 if it means anything. PWM broke and nobody had time to fix it, so Matt just set it to GPIO IIRC. There's actually a good reason now to think again about some kind of PWM on one LED anyway, we discovered at least some GTA02 A5 in the field have the LED drive issue on red. PWM is actually a valid workaround for that. But we expect PWM2 that would drive red LED to be repurposed for tickless clock stuff by Andrzej. So we could do LED PWM in FIQ same way as vibrator. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkjx4fEACgkQOjLpvpq7dMpAYwCeKDJnE+i9BbXgtYL0QUXLQ4Lc wKcAn2qEefmgb7oUkUGOBnqzJz1CT3aJ =CRzt -----END PGP SIGNATURE-----
