If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 7bdab3e72cdc0c77f293cbc8f71ad33cb3a7302a Author: Lev Popov <leo@xxxxxxxxx> Date: Mon Sep 26 14:53:48 2022 +0200 arm64: dts: rockchip: fix quartz64-a bluetooth configuration [ Upstream commit 2dcd7e0c821fe9b663f7d3382b6d2faa8edf2129 ] For "Quartz64 Model A" add missing RTS line to the UART interface used by bluetooth and swap bluetooth host-wakeup and device-wakeup gpio pins to match the boards physical layout. This changes are necessary to make bluetooth provided by the wireless module work. Also set max-speed on the bluetooth device as it's not automatically detected.
