T527 Android13遥控的适配和官方提供的文档有些不一样，按照官方的文档不能够正常适配到自己的遥控器。
首先确保驱动是否有打开CONFIG_AW_IR_RX和CONFIG_RC_DECODERS=y
以及CONFIG_IR_NEC_DECODER=m，这个可以在longan/out/t527对应的目录下的.config查看是否存在相关的项。一般默认是打开的，如果没有就到android13_arm64_defconfig配置里面添加。
然后查看驱动是否有加载到系统里面，可以adb下执行lsmod|grep ir查看是否有加载sunxi_ir_rx和ir_nec_decoder，如果没有加载，可以看一下android/device/softwinner下面的对应项目是否有将CONFIG_AW_SUPPORT_IR这个参数设置为false。这个值为false，驱动文件是不会编译到系统里面的。
驱动加载以后，getevent是可以查看到数据上报的，但是这个时候，按键是没有功能的，这个时候一般都会想到根据getvent上报的数值去改映射文件sunxi-ir.kl。但是这个时候改了也是没有用的，这是因为底层没有添加相应的按键值映射。如果底层添加了相应的按键值映射，sunxi-ir.kl可以不用修改，里面大部分的按键都已经映射好了android系统层按键值。
如何添加自己遥控器的按键值呢？首先打开android/longan/bsp/drivers/ir-rx/sunxi-ir-keymap.h，里面的数组static struct rc_map_table sunxi_nec_scan[]就是我们要添加按键映射的地方。先在adb下执行getevent -l /dev/input/event3，这里/dev/input/event3对应的是"sunxi-ir"的节点。然后按遥控器按键，比如我按一下音量加按键。得到如下值：
bash
getevent -l /dev/input/event3
EV_MSC MSC_SCAN 0000800a
EV_KEY KEY_VOLUMEUP DOWN
EV_SYN SYN_REPORT 00000000
EV_MSC MSC_SCAN 0000800a
EV_SYN SYN_REPORT 00000000
EV_MSC MSC_SCAN 0000800a
EV_SYN SYN_REPORT 00000000
EV_KEY KEY_VOLUMEUP UP
EV_SYN SYN_REPORT 00000000找到上面的带MSC_SCAN的那一行，就是上报的数据，这行第三列第2个数字以后的数据（00800a）就是要填写到上面说的sunxi_nec_scan里面的。上面的按键我们需要在数组中添加如下代码：

遥控器有个按键是鼠标模式，系统默认切换的时候是没有提示的，这个很不友好，如果要添加提示，添加下面修改即可：
