20250619在荣品的PRO-RK3566开发板的Android13系统的uboot阶段就拉高GPIO2C6
2025/6/19 15:10

缘起：荣品的PRO-RK3566项目的GPIO2C6引脚控制着LCD屏的VDDI引脚。
因此需要在上电开机的时候，马上就拉高GPIO2C6【uboot阶段】。

实践证明/【用示波器】确认：
在uboot阶段拉高GPIO控制LCD屏的电源GPIO2C6，发现是在现阶段大概是在上电大概1.4s-1.5s的时候，VDDI和AVDD同时拉高。

   };
}

&pinctrl {
   gpiopower:gpiopower-pwr{
   rockchip,pin =
       <4 RK_PC6 &pcfg_pull_down>;
   };
};

其中箭头指向和数字标点的都可以更改 gpiotest 以及gpiotest-regulator 可以更改为你需要的名字，不重复即可
gpios = <&gpio4 RK_PC6 GPIO_ACTIVE_HIGH>;&gpio4 RK_PC6 是根据GPI04_C6_d 修改; GPIO_ACTIVE_HIGH --->设置为高电平
pinctrl-0 = <&gpiopower>;&gpiopower----->为此截图中的&pinctrl4号标点
regulator-name = "vcc_camear";这个值可随意更改
4号五号可以任意取名，6号需要和上面同步
