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.quoted
It is... for Sebastian. I'm playing with camera now.quoted
I see that you applied this patch: https://git.kernel.org/cgit/linux/kernel/git/pavel/linux-n900.git/commit/?id=051aa3fbf03ac770d8344690f5a936a7f04c6884 Looks like that pinmux is in DTS file incorrect. Can somebody verify it? Maybe Tony?Yes, it is. Sebastian was pretty certain about that.Yes, I'm certain. The bootloader enables the pullup resistors. 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=nokia-bluetooth-dev&id=6b63c111a979d100cfbdd76cb4a6bbadace35216
Maybe send it so we can merge it as a fix during the early -rc cycle? Regards, Tony
