It’s time to report on code flowing upstream again: Following up on our report for Linux 5.19, 6.0 and 6.1 this summarizes the progress on mainline support for the Librem 5 phone and its development kit during the 6.2, 6.3 and 6.4 development cycles.
It’s crucial to describe our boards correctly and we constantly improve that description based on specifications, driver code and the hardware. During the last weeks and months we’ve improved power consumption and completed selfie-camera support among other things:
We improved the serial communication with the BM818 modem:
We’ve written a driver for the i.MX8MQ MIPI CSI2 camera receiver controller and included it in mainline Linux. We continue to support it and optimized it a bit:
Documentation is always underevaluated. During working on camera, we improved Linux documentation a bit:
During this period we contributed 12 Reviewed-by: or Tested-by: tags to patches by other authors. Again we would like to thank everybody who reviewed our patches and helped us supporting the hardware in mainline Linux – especially Shawn for the DT review.
