rk3568 添加IR遥控器
生活中充满了各种波长的电磁波，所谓的可见(色)光就是人眼可见的电磁波谱，其波长为 380~770nm，为了避免遥控器发射的光造成人眼不适及减少一般人造光源干扰，故选用人眼不可见的红外线(Infrared)波长，目前业界遥控器发射头几乎都选用 940nm 波长。
红外线遥控器的应用也是一种无线讯号传输，跟大部分的无线传输技术一样，为了避免环境中同波长电磁波的干扰，故会在其传输讯号上加上如图二所示的载波(carrier frequency)，在遥控应用的载波范围为 30~60kHz，而 38kHz 为最常见的载波频率。
目前红外遥控协议有RC5、 SIRCS、 Sy、 RECS80、Denon、NEC、Motorola、Japanese、SAMSWNG 和 Daewoo 等。Rockchip平台只支持 NEC编码，好在国内电器大多使用该编码协议。

1. rk3568 添加红外遥控
RK平台PWM 有三种工作模式， reference mode, one-shot mode 和 continuousmode. 红外遥
控器就采用 reference mode，这种模式下 PWM 可以捕获输入高低电平的宽度，并产生中断，CPU
接收到中断后去相应的寄存器读取。
1.1 参照原理图添加内核IR的配置
参照原理图，可知使用 PWM3 作为红外遥控接收。
向正在使用设备树添加如下配置。
&pwm3 {
status = "okay";
compatible = "rockchip,remotectl-pwm";
remote_pwm_id = <3>;
handle_cpu_id = <1>;
remote_support_psci = <0>;
pinctrl-names = "default";
pinctrl-0 = <&pwm3_pins>;
ir_key1 {
rockchip,usercode = <0x4040>;
rockchip,key_table =
<0xf2 KEY_REPLY>,
<0xba KEY_BACK>,
<0xf4 KEY_UP>,
<0xf1 KEY_DOWN>,
<0xef KEY_LEFT>,
<0xee KEY_RIGHT>,
<0xbd KEY_HOME>,
<0xea KEY_VOLUMEUP>,
<0xe3 KEY_VOLUMEDOWN>,
<0xe2 KEY_SEARCH>,
<0xb2 KEY_POWER>,
<0xbc KEY_MUTE>,
<0xec KEY_MENU>,
<0xbf 0x190>,
<0xe0 0x191>,
<0xe1 0x192>,
<0xe9 183>,
<0xe6 248>,
<0xe8 185>,
<0xe7 186>,
<0xf0 388>,
<0xbe 0x175>;
};
......
};
查看输入设备，找到刚添加的pwm红外设备。驱动加正常加载，接下来就是对照键值添加遥控器。
# getevents
add device 1: /dev/input/event2
name: "adc-keys"
add device 2: /dev/input/event0
name: "fdd70030.pwm"
add device 3: /dev/input/event3
name: "rk-headset"
add device 4: /dev/input/event1
name: "rk805 pwrkey"
1.2 添加红外按键上报键值(rk平台单独定义)
RK平台可直接查看红外接收，打开键值命令如下：
echo 1 > /sys/module/rockchip_pwm_remotectl/parameters/code_print
内核日志太多，可使用adb 命令过滤直接得到键值。USERCODE 添加遥控dts 对应的 rockchip,usercode，RMC_GETDATA 对应键值可通过rockchip,key_table 转换为rk-input键值。
adb root;adb shell
# cat /dev/kmsg | grep USERCODE -A 2
6,1136,469064745,-;USERCODE=0x4040
6,1137,469091760,-;RMC_GETDATA=b2
6,1138,482889791,-;USERCODE=0x4040
6,1139,482916765,-;RMC_GETDATA=b4
字母和符号键都是 linux 的标准键值，在可以在 include/dt-bindings/input/input.h。
详见 2 input 键值表。
1.3 添加键值转换
Linux标准键值与Android的标准键值并不相同，需要转换文件匹配对应关系。中间转换配置文件会根据红外遥控使用PWM匹配对应PWM标号所属名的配置文件。本文中使用PWM3对应的编号pwm3: pwm@fdd70030 {，键值转换配置文件名为fdd70030_pwm.kl，设备描述文件则为fdd70030_pwm.idc。Android 键值有不懂详见#3Android 键值表。临时调试可手动拷贝到 /vendor/usr/keylayout,重启生效。
- dd70030_pwm.idc
device.internal = 1 #是否为内部设备
audio.mic = 0 #是否带mic
- dd70030_pwm.kl

1.4 自动编译构建
以 rk356x_box 为例增加，需要将 fdd70030_pwm.kl 和fdd70030_pwm.idc 拷贝到 device/rockchip/rk356x_box/rk356x_box/remote_config目录下。并在 rk356x_box/rk356x_box.mk添加拷贝规则，编译时会自动拷贝到指定目录。

Tips
a) "确定"键，是 KEY_REPLY。
b) /vendor/usr/keylayout 与/system/usr/keylayout 作用相同。
c) 红外注册失败，可查看PWM GPIO复用(iomux)。
d) 注册成功后仍然接收不到信号，可使用示波器或者逻辑分析仪直接抓红外接收头信号。
