Hi everyone,
I created the following Draft MR for the Ally firmware files:
https://gitlab.com/kernel-firmware/linux-firmware/-/merge_requests/272
Please comment on it at your leisure. I will remove the Draft status once
all the sign-off members verify it for correctness.
@Shenghao: can you restate publicly the license of the firmware files and if
there are no issues, sign-off on the MR?
Best,

The firmware is now finally merged upstream:
https://gitlab.com/kernel-firmware/linux-firmware/-/merge_requests/317/diffs
For now a symlink was added to make the current driver implementation by
Jonathan work:
https://gitlab.com/kernel-firmware/linux-firmware/-/merge_requests/318/diffs
Jim and Robin from TI will adjust the tas2781_hda_i2c driver to load the
correct firmware per speaker vendor so the different optimized
protection parameters are given.
For example the following can be used to readout the GUID for
calibration data in UEFI BIOS:
status = efi.get_variable(efi_name, &efi_guid, &attr, &total_sz, data);
Example source:
find /sys/firmware/efi/efivars/ -name *-1f52* -print -exec hexdump -C {} \;
/sys/firmware/efi/efivars/CALI_DATA-1f52d2a1-bb3a-457d-bc09-43a3f4310a92
