参考这篇文章：GPIO模拟SPI
1.首先在内核里面打开SPI模拟
Device Drivers --->
[*] SPI support --->
<*> GPIO-based bitbanging SPI Master 2.在设备树里面根节点下面添加复用的GPIO设置：
spi2: spi2{
compatible = "spi-gpio";
#address-cells = <0x1>;
#size-cells = <0>;
//ranges;
gpio-miso = <&pio 4 3 0>;
gpio-mosi = <&pio 4 4 0>;
gpio-sck = <&pio 4 5 0>;
cs-gpios = <&pio 4 6 0>;
num-chipselects = <1>;
pinctrl-names = "default";
pinctrl-0 = <&spi2_pins_a>;
spidev2@0 {
status="okay";
#address-cells = <1>;
#size-cells = <0>;
compatible = "spidev";
spi-max-frequency = <20000000>;
reg = <0>;
};
};3.在pio: pinctrl@1c20800 里面添加引脚：
spi2_pins_a: spi2-pins-pc {
pins = "PE3", "PE4", "PE5", "PE6";
function = "spi2";
bias-pull-up;
}; 4.注释掉LCD相关设备树内容。
5.将MOSI和MISO短接就可以测试回环数据是否正常，使用 ./spidev_test -D /dev/spidev0.0 -v 来进行测试。
注：这里是使用的LCD引脚，我这边板子已经去掉LCD了。

哇酷小二 说：
这个估计和从机也有关，我换了一个其它的SPI传感器（和之前不是同一种传感器），它能够正常使用。
但是之前那个还是不能正常通信，
这就很离谱了。

};
spidev1@1 {

spi-max-frequency = <100000000>;

}; 在这种情况下，测试CS、MOSI、MISO脚都是有波形的。MISO没有波形。

修改设备树之后，出现设备，CS脚也能被拉低。
但是通信不成功，不能正常读取从机的芯片ID，请大家帮我看一下，哪里有错误？
1.直接使用默认的SPI（默认CS 为PC2）, 检测到有/dev/spidev0.0,能够正常使用。
&spi0 {
pinctrl-names = "default";
pinctrl-0 = <&spi0_pins>;
status = "okay";
#address-cells=<1>;
#size-cells=<0>;
spidev@0 {
compatible = "spidev";
spi-max-frequency = <100000000>;
reg = <0>;
};
};2.使用GPIO 来作为SPI的CS脚，检测到有/dev/spidev0.0，示波器测得CS脚在运行时会被拉低，但是通信不成功。
&pio {
spi0_cs_pins: spi0_cs_pins {
pins = "PC2";
function = "gpio_out";
};
};
&spi0 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&spi0_pins &spi0_cs_pins>;
cs-gpios = <&pio 2 2 GPIO_ACTIVE_HIGH>;
#address-cells=<1>;
#size-cells=<0>;
spidev@0 {
compatible = "spidev";
spi-max-frequency = <100000000>;
reg = <0>;
};
};3.SPI复用，有多个CS脚。检测到有/dev/spidev0.0 、/dev/spidev0.1 。使用/dev/spidev0.0进行通信，示波器测得CS脚（PC2）在运行时会被拉低，但是通信不成功。
&pio {
spi0_cs_pins: spi0_cs_pins {
pins = "PC2","PE20";
function = "gpio_out";
};
};
&spi0 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&spi0_pins &spi0_cs_pins>;
cs-gpios = <&pio 2 2 GPIO_ACTIVE_HIGH>,<&pio 4 20 GPIO_ACTIVE_HIGH>;
#address-cells=<1>;
#size-cells=<0>;
spidev0@0 {
compatible = "spidev";
spi-max-frequency = <100000000>;
reg = <0>;
};
spidev1@1 {
compatible = "spidev";
spi-max-frequency = <100000000>;
reg = <1>;
};

按理说，在网线插入的时候，/sys/class/net/eth0/carrier 这个文件里面的值就会被改变。epoll_wait 就会监测到，并且去读取这个文件的值。但是知道为什么，我多次插拔网线后，都没有触发epoll_wait，求赐教。。。

救命呀！晕哥，我把模块连接到虚拟机上面，一直找不到蓝牙装置。

需要烧录正确的设备树， sun8i-v3s-licheepi-zero.dtb
我之前烧录了sun8i-v3s-licheepi-zero-dock.dtb
结果里面就没有文件。
