   4 Subject: [PATCH] ARM: dts: bcm2838-rpi-4-b: Backport BT part from
   5  upstream
   6
   7 The CYW43455 on the Raspberry Pi 4 doesn't use an external pin as lower
   8 power clock anymore. So drop the GPIO clock from pinctrl. While we are at
   9 this add the missing declaration of hardware flow control.
