You can decompile the dtb from a working bluetooth ap6255 or Broadcom BCM43455 with dtc -I dtb -O dts <file>
dtc -I dtb -O dts ./cache/sources/u-boot/h6-hdmi-rebased-1/arch/arm/dts/sun50i-h6-orangepi-lite2.dtb
has only the debug port
uart0-ph {
pins = "PH0", "PH1";
function = "uart0";
phandle = <0x9>;
};
Im missing the pindef uart1 and pcm for the drive
uart1_pins: uart1-pins {
pins = "PG6", "PG7";
function = "uart1";
};
uart1_rts_cts_pins: uart1-rts-cts-pins {
pins = "PG8", "PG9";
function = "uart1";
};
and uart1
&uart1 {
pinctrl-names = "default";
pinctrl-0 = <&uart1_pins>, <&uart1_rts_cts_pins>;
status = "okay";
};
