AM437x-evm 4.4内核2659摄像头不识别

13301318660

在4.4内核下，按照开发板提供的3.14内核的dts编写2659相关参数，启动后发现摄像头没有识别
使用dmesg查看，有如下信息
root@am437x-evm:~# dmesg | grep 2659
[    7.308916] ov2659 0-0030: link-frequencies property not found or too many

查看TI SDK 4.4内核的dts文件，发现和3.14的有区别

创龙3.14 内核

请问在4.4内核下如何修改

4.4内核不是只支持IDK板吗？这个DTS文件可以直接编译，用在EVM板上吗？
