请教一下，为什么我的AXP203的电源芯片在Power_supply下没有内容？按原来小白菜的帖子我的配置了驱动目录下的两个选项。也看了一下axp209.dtsi的内容，也看不出有什么错误，按说这是个官方标配，不应该有任何问题才对。但现就是电池部分没有任何信息。希望有做过的朋友提点一下，不胜感激。

加了也调试过，不是驱动没加，驱动加载了，那个DTS也是标准的，无须修改。但编译后的结果是它根本就没有产生 电池信息。

不是这样的，我原来的DTS有写一个中断信息，但因为我们的芯片没有接中断IO，所以本质上是没有意义的。而且我也打电话问过代理商，不接IRQ是没有问题的，可以用。

有没有QQ？或才到晕哥的群里聊啊。
首先是有骗过去的。但是也是空的啊

可以骗过去，但依然没什么用
