GPIO0 on the expander is not connected. This means that the shutdown-gpios property of the bluetooth node is incorrect. Furthermore, I've been told that the current production 3B+ is the same in this regard - a change since the 3B+ schematic with which the firmware support was developed - so the 3B+ DTS should ideally also be changed, although leaving it as it stands is likely to make little practical difference.

I tested this on my RPi 3 A+ with some gpio-exp hacking and can confirm this behavior. I don't know the reason for this design decision, but both drivers (wifi and BT) can't share the control of GPIO1. Additionally we can't give the control to only one of them, because the other one could be unexpectedly tied into reset. So i decided to drop the reset control of both ones with all the consequences (no power management, default baudrate usage of BT) in V4 of this series. > > Furthermore, I've been told that the current production 3B+ is the same in this > regard - a change since the 3B+ schematic with which the firmware support was > developed - so the 3B+ DTS should ideally also be changed, although leaving it > as it stands is likely to make little practical difference. Oh dear. I think there is no hurry for changing 3B+. So i would like to wait until this series has been applied.

How did you > write/test this? i have a Raspberry Pi 3 A+ and the firmware seems to use a runtime generated DT. So i dumped the DTS of a 3 A+ and a 3 B+ from procfs. Based on the procfs diff i modified the upstream 3B+ source to get a 3A+ . Please consider this series as optional for 5.0. I won't submit any further patch for the next release cycle. But maybe Phil can provide some feedback. Regards Stefan ^ permalink raw reply [flat|nested] 10+ messages in thread

Comparing to the pi3b+, it looks like the changes I would expect for the board, so the series is: Reviewed-by: Eric Anholt <eric@anholt.net> -------------- next part -------------- A non-text attachment was scrubbed...
