Sadly it looks like the patch causes conflicts with at least one firefly board in a kernelci lab. My own is currently not ready to use, so I cannot look myself right now. The issue kernelci people described sounded quite a lot like the one in your commit message, so my current theory is that the suspend-voltage-selector must in some form corespond to the cpu_b_sleep_h gpio setting we're currently not handling at all, which would therefore depend on how the bootloader sets this up.
