Hi!
This driver seems to have fallen by the wayside because, while otherwise fine, it has a firmware update feature that requires a blob that is not in the linux-firmware repo.[1]
Whatever the cause for that may be, the update code is entirely optional (my chip works fine with whatever firmware is currently installed), so I have removed it in order to get this merged after all. I have also followed various trivial API changes that have piled up since 2016; see the individual patches for details.
I'm using this driver on an Acer Chromebook R13 ("Elm"); see https://github.com/uli/kernel/tree/elm-working-5.4.
Thanks for your effort to get things upstream. I just tried your branch on my R13. I had to do a trivial config change I had to do, as I don't have and care about the bluetooth FW right now.
Thank you for testing!
But after that my screen keeps black. I was able to build and boot elm-working-5.3 and elm-working-5.2.
Unfortunatley I don't have a serial console on the Chromebook, so it's difficult to find out where it hangs. Can you please double check if your new elm-working-5.4 actually really works?
No, it doesn't. :( It seems I forgot to run mkimage/vbutil_kernel when testing... I have pushed a fix to the elm-working-5.4 tree, and I will send a v20 tomorrow. Sorry for the inconvenience.
