Subject: [PATCH] Bluetooth: btmtksdio: Add in-band wakeup support
Date: Fri, 10 Jun 2022 08:17:17 +0800	[thread overview]
Message-ID: <742cdffcf110e1601257207fb2b0d3f426d4008c.1654819586.git.objelf@gmail.com> (raw)

From: Sean Wang <sean.wang@mediatek.com>

'ce64b3e94919 ("Bluetooth: mt7921s: Support wake on bluetooth")'
have added the waken-on-bluetooth via dedicated GPIO.

The patch extends the function to the waken-on-bluetooth via SDIO DAT1 pin
(inband wakeup) when the SDIO host driver is able to support.
