Maybe:
Commit ce64b3e94919 ("Bluetooth: mt7921s: Support wake on bluetooth")
adds the wake on bluethooth via a dedicated GPIO.

Maybe:
Extend the wake-on-bluetooth to use the SDIO DAT1 pin (in-band wakeup),
when supported by the SDIO host driver.
How did you test this? In what datasheet is it documented?

Maybe:
Mark if MMC host supports wake on bluetooth by SDIO
