git conflict

0

git conflict 是日常协作中必不可少的。

在gitlab的web页面上，有三种处理conflict的视图，其中line的文本方式最灵活。

这种方式中：

其中<<<<<<< HEAD 到 ======= 中间的内容是local提交的。

======= 到 >>>>>>> commit-id 是远程仓库中的内容。

示例：

<<<<<<< HEAD

新提交的代码xxx

=======

远程仓库的代码xxx

>>>>>>> commit-id

of_get_gpio说明

0

/**

  • of_get_gpio() - Get a GPIO number to use with GPIO API
  • @np: device node to get GPIO from
  • @index: index of the GPIO
  • Returns GPIO number to use with Linux generic GPIO API, or one of the errno

  • value on the error condition.
    /
    static inline int of_get_gpio(const struct device_node     np, int index)
    {
    return of_get_gpio_flags(np, index, NULL);
    }

    这个index 表示gpios节点的索引位置，gpios支持多个节点，每个节点由<gpio_chip gpio_num default_level>
    eg:
    gpios = <&ap_gpio 145 0 &ap_gpio 144 0>;
