20230210使AIO-3568J开发板在Android12下调通3个USB
2023/2/10 10:00
0、默认编译RK3568的Andorid12的rk3568-evb2-lp4x-v10.dts，2个USB2.0接口的鼠标可以用。
并列USB3.0接口的上面的鼠标不能用。USB3.0接口下面可以连接ADB。

1、配置USB3.0接口
Z:\ap6275s-rk3568-android12\kernel-4.19\arch\arm64\boot\dts\rockchip\rk3568-evb.dtsi
vcc5v0_host: vcc5v0-host-regulator {
compatible = "regulator-fixed";
regulator-name = "vcc5v0_host";
regulator-boot-on;
regulator-always-on;
regulator-min-microvolt = <5000000>;
regulator-max-microvolt = <5000000>;
enable-active-high;
gpio = <&gpio0 RK_PA6 GPIO_ACTIVE_HIGH>;
vin-supply = <&vcc5v0_usb>;
pinctrl-names = "default";
pinctrl-0 = <&vcc5v0_host_en>;

修改为：

编译内核之后，并列USB3.0接口的上面的鼠标可以用了，但是2个USB2.0接口都不能用了！
编译 kernel：
make ARCH=arm64 rockchip_defconfig android-11.config
make ARCH=arm64 BOOT_IMG=../rockdev/Image-rk3568_s/boot.img rk3568-evb2-lp4x-v10.img -j16

2、配置USB2.0接口
由于根据rk3568-firefly-aioj.dts配置rk3568-evb2-lp4x-v10.dts，配置全部3个USB接口老是异常。
于是将firefly修改的rk3568-firefly-aioj.dts收拾/还原成为rk3568-evb2-lp4x-v10.dts
很容易/艰难地知道控制2个USB2.0接口的代码块！
rk3568-firefly-aioj.dts修改为：rk3568-evb2-lp4x-v10.dts
rk3568-firefly-aioj.dtsi修改为：rk3568-evb2-lp4x-v10.dtsi
rk3568-firefly-port.dtsi和rk3568-firefly-core.dtsi修改为：rk3568-evb2-lp4x-v10.dtsi
rk3568-firefly-aioj.dts
#include "rk3568-firefly-aioj.dtsi"
rk3568-firefly-port.dtsi
#include "rk3568-firefly-core.dtsi"
#include "rk356x-firefly-demo.dtsi"（这里不需要）
rk3568-firefly-core.dtsi
firefly_defconfig和firefly_wifi.config修改为：rockchip_defconfig
