[PATCH] arm64: dts: rockchip: fix quartz64-a bluetooth configuration

From: Lev Popov
Date: Sun Sep 25 2022 - 08:32:42 EST


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.
