V3s/S3 Linux 测试 轮询/中断 GPIO 按钮驱动程序 / 旋转编码器 等

GPIO KEY 按键驱动(轮询)测试:

参考: https://github.com/ARM-software/u-boot/blob/master/arch/arm/dts/sun4i-a10-inet9f-rev03.dts


1. Linux驱动配置 gpio keys poll 驱动:

CONFIG_KEYBOARD_GPIO_POLLED=y


2. arch/arm/boot/dts/sun8i-v3s.dtsi 添加引脚定义:

key_pins: key_pins@0 {
               pins = "PB0", "PB1";
               function = "gpio_in";
               bias-pull-up;
               };

3. arch/arm/boot/dts/sun8i-v3s-licheepi-zero.dts 添加:

#include <dt-bindings/input/input.h>

       gpio_keys {
               compatible = "gpio-keys-polled";
               pinctrl-names = "default";
               pinctrl-0 = <&key_pins>;
               #address-cells = <1>;
               #size-cells = <0>;
               poll-interval = <20>;

               button@0 {
                       label = "Left Joystick Left";
                       linux,code = <ABS_X>;
                       linux,input-type = <EV_ABS>;
                       linux,input-value = <0xffffffff>; /* -1 */
                       gpios = <&pio 1 0 GPIO_ACTIVE_LOW>; /* PB0 */
               };

               button@1 {
                       label = "Left Joystick Right";
                       linux,code = <ABS_Z>;
                       linux,input-type = <EV_ABS>;
                       linux,input-value = <1>;
                       gpios = <&pio 1 1 GPIO_ACTIVE_LOW>; /* PB1 */
               };
       };

4. 编译烧录运行测试:

参考: https://www.kernel.org/doc/Documentation/devicetree/bindings/input/gpio-keys.txt

接上帖, GPIO 也可以换作 interrupts, Linux 官方文档提示 二选一

gpio_keys {
                compatible = "gpio-keys";
                pinctrl-names = "default";
                pinctrl-0 = <&key_pins>;
                #address-cells = <1>;
                #size-cells = <0>;
                autorepeat;
                button@0 {
                        label = "Key back";
                        linux,code = <KEY_BACK>;

                        interrupt-parent = <&pio>;
                        interrupts = <1 0 IRQ_TYPE_EDGE_FALLING>;//PB0

                };


                button@1 {
                        label = "Key home";
                        linux,code = <KEY_HOME>;

                        interrupt-parent = <&pio>;
                        interrupts = <1 1 IRQ_TYPE_EDGE_FALLING>; //PB1
                };

Re: V3s/S3 Linux 测试 轮询/中断 GPIO 按钮驱动程序 / 旋转编码器 等

我的设备树:

       gpio_keys {
               compatible = "gpio-keys-polled";
               pinctrl-names = "default";
/*               pinctrl-0 = <&key_pins>;*/
               #address-cells = <1>;
               #size-cells = <0>;
               poll-interval = <20>;



               button@0 {
                        label = "GPIO Key Up";
                        linux,code = <KEY_UP>;
                        gpios = <&pio 7 1 GPIO_ACTIVE_LOW>; /* PH1 */
               };
               button@1 {
                        label = "GPIO Key Enter";
                        linux,code = <KEY_ENTER>;
                        gpios = <&pio 7 8 GPIO_ACTIVE_LOW>; /* PH8 */
               };

               button@2 {
                        label = "GPIO Key Down";
                        linux = <KEY_DOWN>;
                        gpios = <&pio 7 7 GPIO_ACTIVE_LOW>; /* PH7 */
               };

       };

安装驱动, 并不能生成 event 设备:

晕, 搞错了

应该是
                        linux,code = <KEY_DOWN>;


现在可以了。 奇怪了, 居然还能通过编译。

晕哥,我的v3s和你的中断代码一模一样,cat/proc/interrupt也一样,就是我的是event1,但是信息和你的event2一样,但是死活进不了中断。试了下你的那个轮训key可以触发,io口都一样的。请问有什么解决办法可以尝试吗?会不会是内核原因?

Re: V3s/S3 Linux 测试 轮询/中断 GPIO 按钮驱动程序 / 旋转编码器 等

我在用f1c100s的测按键轮询 在对应的设备树文件添加内容

key_pins: key_pins@0 {
                                pins =  "PE4";

                                function = "gpio_in";
                                bias-pull-up;
                        };


gpio_keys {
               compatible = "gpio-keys-polled";
               pinctrl-names = "default";
               pinctrl-0 = <&key_pins>;
               #address-cells = <1>;
               #size-cells = <0>;
               poll-interval = <20>;

               button@0 {
                       label = "Left Joystick Right";
                       linux,code = <ABS_Z>;
                       linux,input-type = <EV_ABS>;
                       linux,input-value = <1>;
                       gpios = <&pio 4 4 GPIO_ACTIVE_LOW>; /* PE4 */
               };
       };

然后编译打包烧录 开机提示io被占用 没有相应的/dev/evenX

我查了设备树 发现根本没占用 换了几个IO都是这样
然后我把这句屏蔽掉了 pinctrl-0 = <&key_pins>;
发现就可以了 有相应的/dev/evenX 测试也有效 只是没有pinctrl-0 = <&key_pins>;里的上拉作用
不知道为什么会这样

会进入吗USB烧录模式,系统设备里面会出现改该设备,需要安装驱动配合烧录软件可以用。

挖一下(
F1C200S,亲测可用

 pio {
         ............

                   key_pins: key-pins  {
				pins = "PD1","PD2","PD11","PD15";
				function = "gpio_in";
				drive = <0>;
				pull = <1>;
				bias-pull-up;
		    };
}

\ 下
gpio_keys {
        compatible = "gpio-keys";
        pinctrl-names = "default";
		pinctrl-0 = <&key_pins>;
		status = "okay";
        #address-cells = <1>;
        #size-cells = <0>;
        autorepeat;

        button@0 {
                label = "Key back";
                linux,code = <130>;
                interrupt-parent = <&pio>;
                interrupts = <3 1 IRQ_TYPE_LEVEL_LOW>;//PB0
				 
        };

         button@1 {
                 label = "Key home";
                 linux,code = <131>;

                interrupts = <3 2 IRQ_TYPE_LEVEL_LOW>;//PB0
         };

	};

关于pinctrl-0 = <&key_pins>;管脚冲突,我提一点我的看法,单纯是全志的BUG(可能性很大)。另外pinctrl子系统和gpio-key子系统貌似是互相独立的,可能互相之间的支持不是很好?pinctrl中申请使用管脚,然后gpio-key又申请了一遍?用我上面的代码,中断+pinctrl就没报错。

这是我设备树的配置:

    rotary@0 {
            compatible = "rotary-encoder";
            gpios = <&pio PE 5 0 6 1 0>, <&pio PE 6 0 6 1 0>;
            linux,axis = <0>; /* REL_X */
            rotary-encoder,relative-axis;
            status = "okay";
        };
