WhyCan Forum(哇酷开发者社区)

各位大佬，有个问题想请各位帮帮忙，目前用全志的F1C100S做红外解码IR_RX，嵌入式Linux的版本是5.4.77，参考资料是这个链接：https://blog.csdn.net/lzj85/article/details/124220756
目前IR_RX已经可以启动：
# cat /proc/bus/input/devices
I: Bus=0019 Vendor=0001 Product=0001 Version=0100
N: Name="sunxi-ir"
P: Phys=sunxi-ir/input0
S: Sysfs=/devices/platform/soc/1c22c00.cir/rc/rc0/input2
U: Uniq=
H: Handlers=kbd event1
B: PROP=20
B: EV=100017
B: KEY=1000000 0 0 0 0
B: REL=3
B: MSC=10
//这是设备树里的IR_RX的相关配置：
cir: cir@1c22c00 {
            compatible = "allwinner,sun6i-a31-ir";
            //compatible = "allwinner,sun4i-a10-ir";
            //compatible = "allwinner,suniv-f1c100s-ir";
            clocks = <&ccu CLK_BUS_IR>, <&ccu CLK_CIR>;
            clock-names = "apb", "ir";
            resets = <&ccu RST_BUS_IR>;
            interrupts = <6>;
            reg = <0x01c22c00 0x400>;
            pinctrl-names = "default";
            pinctrl-0 = <&cir_pins_f>;
            status = "okay";
        };
cir_pins_f: cir_pins_f {
                pins = "PF0";
                function = "ir";
                allwinner,muxsel = <4>;
                allwinner,drive = <1>;
                allwinner,pull = <0>;
            };
//这是内核启动的过程：

问题是在内核启动的时候出现了[ 1.272883] suniv-f1c100s-pinctrl 1c20800.pinctrl: unsupported function ir on pin PF0，接上红外接收模块到PF0管脚，然后evtest /dev/input/event1，就会停在Testing ...不动，请问是怎么回事？
