根据开发板新设计的电路，内核无法完全启动，找不到sound-wm8960

大家好！我自己根据飞凌imx8mq开发板修改的电路板，去掉了WM8960语音芯片、wifi模块、4G模块和时钟芯片。然后用自带的内核启动到一般无法启动。错误如下：

[ 3.337822] imx-wm8960 sound-wm8960: failed to find codec platform device
[ 3.346515] imx6q-pcie 33800000.pcie: 33800000.pcie supply epdev_on not found , using dummy regulator
[ 3.346898] imx6q-pcie 33c00000.pcie: 33c00000.pcie supply epdev_on not found , using dummy regulator
[ 3.347640] imx-wm8960 sound-wm8960: failed to find codec platform device

这块要怎么解决，内核中需要修改设备树和驱动，具体那两个文件，怎么修改？

设备树路径：imx8mq/OK8MQ-linux-sdk/OK8MQ-linux-kernel/arch/arm64/boot/dts/freescale/ok8mq-evk.dts

在设备树中将wm8960的节点注释掉，

djh谢谢您回复

按照你这种方式做了现在语音芯片的问题不见了，最后还是停在了这里

这个问题需要注释掉那部分，内核裁剪我不太会，麻烦您了，核心板用的是飞凌的，地板只是去掉了WM8960语音芯片、wifi模块、4G模块和时钟芯片

您在设备树中将对rtc、wifi、4G的节点注释掉，用 / 查找所在位置，进行注释，设备树中的节点与硬件是一一对应的，不能直接用我们的镜像，

明白，谢谢您回答，知道怎么处理了
