With your suggestions, the patch becomes much simpler:

I need to build a kernel + rootfs + FW to test the proposed solution,
then I can spin a formal submission.

(I didn't understand why this patch requires Dmitry's series?)

Do I need to submit a symmetric patch to linux-firmware to define bit 23?
And also a patch to add the bit to some firmwares? (All msm8998 FWs?)
