am3354的核心板，电源芯片换了,emmc型号也换了，怎么改设备树和uboot?

请问你的意思是硬件上电源芯片更换了，在uboot 和设备树上不需要修改吗？
在原本的设备树中有这么一段

这一段需要修改吗？硬件上电源芯片已经换成tps65217

am335x-bone开发板使用了TPS65217作为PMIC芯片，你的dts可以参考它的

你好！
我修改了设备树。在一开始的时候，使用sd卡启动，结果卡在内核启动中。后来我对比了启动信息，发现下一步是挂载文件系统，然后找到设备树，在SD卡设置的地方发现供电与之前的电源芯片有关，后来我修改了这个地方的配置，系统启动。但问题没有结束，启动的信息中有 PM: Cannot get wkup_m3_ipc handle,并且最后也没有处理好这里。
在之前的系统中，虽然也会出现这个问题，但开机完成后，查看开机信息
debian@onecut:~$ dmesg | grep m3
[ 1.973704] wkup_m3_ipc 44e11324.wkup_m3_ipc: could not get rproc handle
[ 2.117571] input: ti-tsc as /devices/platform/ocp/44e0d000.tscadc/TI-am335x-tsc/input/input0
[ 2.206831] remoteproc remoteproc0: wkup_m3 is available
[ 2.223464] PM: Cannot get wkup_m3_ipc handle
[ 2.448264] remoteproc remoteproc0: powering up wkup_m3
[ 2.448292] remoteproc remoteproc0: Booting fw image am335x-pm-firmware.elf, size 217148
[ 2.448563] remoteproc remoteproc0: remote processor wkup_m3 is now up
[ 2.448615] wkup_m3_ipc 44e11324.wkup_m3_ipc: CM3 Firmware Version = 0x192
上面这段是正常的情况，但在更改了电源芯片的系统中只有
PM: Cannot get wkup_m3_ipc handle
没有emoteproc remoteproc0: powering up wkup_m3和remoteproc remoteproc0: remote processor wkup_m3 is now up
这是目前能看到的影响，其他的不知道会不会有影响。
请问有没有方法能更安全的处理更换电源芯片的设备树？或者上面这个问题有没有什么处理办法？
谢了！
