Subject: [PATCH] overlays: pi3-disable-bt: Clear out bt_pins node
|
2019-07-09 18:32:28 +00:00
|
|
|
|
|
|
|
|
The pi3-disable-bt overlay does not (and cannot) delete the bt_pins
|
|
|
|
|
node, but emptying its properties (including brcm,pins) is a way of
|
|
|
|
|
signalling to the hciuart systemd service that Bluetooth has been
|
|
|
|
|
disabled.
