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:

晕， 搞错了
linux = <KEY_DOWN>;
应该是
linux,code = <KEY_DOWN>;
现在可以了。 奇怪了， 居然还能通过编译。

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

您好，V3s linux的系统如何裁剪出来的？V3s 不是自带的camdroid系统么，我用的我在lichee下build.sh pack编译出来的sun8iw8p1_linux_tiger-cdr_uart0.img镜像使用PhoenixUSBPRO无法烧写，但是编译成camdroid就可以烧写，介质时nand，能告诉如何编译linux可烧写的系统镜像么

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

根据楼主代码，在V3S上编码器测试成功！

Re: V3s/S3 Linux 测试 轮询/中断 GPIO 按钮驱动程序 / 旋转编码器 等
我也想知道为什么会这样？
我在用f1c100s的测按键轮询 在对应的设备树文件添加内容
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

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。
晕哥 我这设备管理器提示
USB 设置地址请求失败。是不是说芯片坏掉了呀

Re: V3s/S3 Linux 测试 轮询/中断 GPIO 按钮驱动程序 / 旋转编码器 等
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>;
interrupt-parent = <&pio>;
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。

大佬们，f1c100s的tina，加载编码器的驱动，内核直接奔溃了，这是怎么回事啊？

@jkl
我记得PE没有中断
我看了芯片手册，PE有外部中断
我怀疑可能是这个帖子的原因：

@晕哥
我用的是V3S linux5.2
代码复制过去的，event出不来，原有的matrix key是evet0，lradc是event1，触摸屏是event2，串口2也注释掉了，开机没有打印PB2中断对应的inputx

搞定了，引脚定义没放在pinctrl下面
