环境:使用版本r38.4, custom板卡参考p3971
我们参考p3971板卡设计了自己的板子，然后搭配p3834 SOM,使用uphy_tx13 连接了一个phy-aqr113c
在驱动加载的时候出现如下报错

我感觉这是和uphy的配置有关，然后我查看了
tegra264-bpmp-3834-0008-3971-xxxx.dts
中默认使用的是
uphy {
status = "okay";
uphy0-config = <0x07>;
uphy1-config = <0x00>;
};
通过查看uphy1-lane-mapping-options
我尝试将uphy1-config = <0x00>; 改成 uphy1-config = <0x07>;然后重新烧录，发现烧录会报错提示bpm配置错误
我想请问一下这个p3971的板载应该怎么修改uphy1的功能
