    MP157-2-TF-A移植：


    正点原子第九章内容：
    自己记的笔记，详细内容请参考正点原子教程STM32MP1 嵌入式 Linux 驱动开发指南2.0。

    1. TF-A移植：

    1.1 新建开发板的设备树

    VSCODE 打开 tf-a-stm32mp-2.2.r1\fdts 目录并且打开终端在这里插入图片描述
    复制这两个文件stm32mp157d-ed1.dts，stm32mp15xx-edx.dtsi 为atk，我测试了qcy不能用。。。

    cp stm32mp157d-ed1.dts stm32mp157d-atk.dts
cp stm32mp15xx-edx.dtsi stm32mp157d-atk.dtsi

    在这里插入图片描述
    头文件名称也要修改
    在这里插入图片描述

    1.2 修改设备树电源管理

    打开 stm32mp157d-atk.dtsi 文件，第 54~281 行的内容全部删除掉，pmic节点信息内容全部删除。
    在这里插入图片描述
    在这里插入图片描述
    将上面vin 节点内容全部删除掉，也就是将 17~23 行代码删除掉，替换为下面的
    代码：
    在这里插入图片描述

    vddcore: regulator-vddcore {
        compatible = "regulator-fixed";
        regulator-name = "vddcore";
        regulator-min-microvolt = <1200000>;
        regulator-max-microvolt = <1350000>;
        regulator-off-in-suspend;
        regulator-always-on;
    };

    v3v3: regulator-3p3v {
        compatible = "regulator-fixed";
        regulator-name = "v3v3";
        regulator-min-microvolt = <3300000>;
        regulator-max-microvolt = <3300000>;
        regulator-off-in-suspend;
        regulator-always-on;
    };	

    vdd: regulator-vdd {
        compatible = "regulator-fixed";
        regulator-name = "vdd";
        regulator-min-microvolt = <3300000>;
        regulator-max-microvolt = <3300000>;
        regulator-off-in-suspend;
        regulator-always-on;
    };

    vdd_usb: regulator-vdd-usb {
        compatible = "regulator-fixed";
        regulator-name = "vdd_usb";
        regulator-min-microvolt = <3300000>;
        regulator-max-microvolt = <3300000>;
        regulator-off-in-suspend;
        regulator-always-on;
    };

    1.3修改TF卡和EMMC设备树

    继续操作 stm32mp157d-atk.dtsi 这个文件，找到“sdmmc1”和“sdmmc2”这 2 个节点。

    在这里插入图片描述
    将 sdmmc1 和 sdmmc2 节点改为如下所示内容:
    在这里插入图片描述

    &sdmmc1 {
	pinctrl-names = "default";
	pinctrl-0 = <&sdmmc1_b4_pins_a &sdmmc1_dir_pins_a>;
	st,neg-edge;
    broken-cd;
	bus-width = <4>;
	vmmc-supply = <&v3v3>;
	status = "okay";
};

&sdmmc2 {
	pinctrl-names = "default";
	pinctrl-0 = <&sdmmc2_b4_pins_a &sdmmc2_d47_pins_a>;
	non-removable;
	st,neg-edge;
	bus-width = <8>;
	vmmc-supply = <&v3v3>;
    vqmmc-supply = <&v3v3>;
	status = "okay";
};

    1.4 修改USBOTG设备树

    继续操作 stm32mp157d-atk.dtsi，找到
    “usbotg_hs”这个节点。
    在这里插入图片描述
    将 usbotg_hs 节点改为如下所示内容：
    并文件里面添加了一个名为“usbphyc”的节点。
    在这里插入图片描述

    &usbotg_hs {
	phys = <&usbphyc_port1 0>;
	phy-names = "usb2-phy";
	usb-role-switch;
	status = "okay";
};

&usbphyc {
	status = "okay";
};
