Hello,想请教一下，您那边底板上的矩阵按键驱动在哪里？

我设备树中查看到了，然后我昨天测试的时候发现这些按键，只有确认和返回，没有home按键，和音量+和音量-？这个做进去应该不难吧？

hlm@Server:/users/hlm/9_Edge$ grep -rn "khadas-matrix-keypad" kernel/drivers/
kernel/drivers/input/keyboard/khadas-matrix-keypad.c:452:       { .compatible = "khadas-matrix-keypad" },
kernel/drivers/input/keyboard/khadas-matrix-keypad.c:462:               .name   = "khadas-matrix-keypad",

上面是Captain板子才有的按键矩阵

rk3399-android.dtsi

	rk_key: rockchip-key {
		compatible = "rockchip,key";
		status = "okay";

		io-channels = <&saradc 1>;

		power-key {
			gpios = <&gpio0 5 GPIO_ACTIVE_LOW>;
			linux,code = <116>;
			label = "power";
			gpio-key,wakeup;
		};

		home-key {
			linux,code = <102>;
			label = "home";
			rockchip,adc_value = <70>;
		};

	};

hlm@Server:/users/hlm/9_Edge$ grep -rn "rockchip,key" kernel/drivers/                    
Binary file kernel/drivers/input/keyboard/built-in.o matches
kernel/drivers/input/keyboard/rk_keys.c:192:    { .compatible = "rockchip,key", .data = NULL},

这是Edge和edge-v的按键驱动
