According to the devicetree binding the shutdown and device wake
|
||||
GPIOs are optional. Since commit 3e81a4ca51a1 ("Bluetooth: hci_bcm:
|
||||
Mandate presence of shutdown and device wake GPIO") this driver
|
||||
won't probe anymore on Raspberry Pi 3 and Zero W (no device wake GPIO
|
||||
connected). So fix this regression by reverting this commit partially.

Instead of keeping the firmware's pull settings, we better apply
|
||||
them via the devicetree pin control. Start with the RPi Zero W relevant
|
||||
first to keep the effort low.
