Subject: [PATCH] ARM: dts: bcm2838-rpi-4-b: Backport BT part from
|
||
|
|
upstream
|
||
|
|
|
||
|
|
The CYW43455 on the Raspberry Pi 4 doesn't use an external pin as lower
|
||
|
|
power clock anymore. So drop the GPIO clock from pinctrl. While we are at
|
||
|
|
this add the missing declaration of hardware flow control.
