Following up on our report for Linux 5.9 and 5.10, this summarizes the progress on mainline support for the Librem 5 phone and its development kit during the 5.11 development cycle.
In order to maintain support for the devkit and the phone, we continuously update the mainline default configuration:
The mainline solution to dynamically scale internal bus frequencies relies on the interconnect (and devfreq) framework. We found a small piece that has been missing for imx8mq:
The display panel driver saw some minor updates:
With the experience with using the phone for the last couple of months, we could improve the battery fuel gauge driver a bit:
Our work to make sure we can properly charge the phone and use its Type-C feature like Displayport resulted in the following additions during this development period:
Equally important are the changes to a regulator device that allow one to turn off the GPU regulator, to the mxsfb display driver and to the etnaviv GPU driver. Read the commit messages for more details.
During these rounds, we contributed 6 Reviewed-by: or Tested-by: tags to patches by other authors. We would also like to thank everybody who reviewed our patches and helped us support the hardware in mainline Linux.
