I could scan for devices. The code is still racy, though. It's most likely related to the newly introduced idle code. (Without sending the BT module to correctly idle the bcm2048 does not work correctly at all) I was quite busy the last few weeks and did not manage to find much time for kernel work. Now I will first have to catch up with my power-supply tree. > It is... for Sebastian.

Note, that the wrong DTS entry is not in mainline. My bluetooth branch has a fixed DTS patch instead of a fixup patch on top of the broken one: https://git.kernel.org/cgit/linux/kernel/git/sre/linux-n900.git/commit/?h= =3Dnokia-bluetooth-dev&id=3D6b63c111a979d100cfbdd76cb4a6bbadace35216 -- Sebastian --heih7bufcowefweg Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE72YNB0Y/i3JqeVQT2O7X88g7+poFAlhRScAACgkQ2O7X88g7 +pqBGw/9Gng2PM9INPQbLbwOl6/FJsIVm2xQrVa7gLU0Kgzix/zhIBJtOt5Uyk+N FVdIgn/KWGGca0ZwhoW5gyQg7Swy0lC8H9XKAamrbW04c5C1+k+xPnSGXWFvmJ4b JG/7kAT4HxayYmYl4dGS7fSGgp63xG1h209EsQgdn4UbGJiOnP2Q5bViVil/FfiX JtVEpAwKVlbIjDcGX+3DSFPLt5dpHJn4U8ww0jgxvr5QFceElSR0NxSs1oNtkEja NrePTrIReWoJnmL420zsYiB6/U77+gDyl0YKHeKD9WBxz2gm4cIZE1JJdqzKB7PV 5HF5Vm09jIIwHX4MoKwOs8Wax8s6ulwEmywvdZOnPrpDSxu9An1L8IibrA5KCiEK iO+A6bpBbrRV7+Y9wt+oEK5+hkSacAOQSUNE7rFMmG4U+y+ZbS+Immj0bCPUvXtW MwmMEgQpMQJg+PFTwLKxL3s6CBICn9iNxznj98JnJOJzIlqgc7p0cOjk3GTuk0Z1 Cmux4uJjQunLjwT6s5lkbiywIAp40PN98dhnfsUnOPFZXr74ZfTX6vzyXSs5OWQR Hpe1A29ACRhgqeEopiihHx84nlQSQ2CbNXvN2LZhFdSJCksnDx+L+38WEZofq77t JzZ5D9C2ELooIwhAgKpY0nWcW1igfREDTKSNFYIplWw/GUt2p9w= =dzi5 -----END PGP SIGNATURE----- --heih7bufcowefweg-- --===============5895599743950194113== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel --===============5895599743950194113==--
