SOLVED 多通道相机设备树设置

[lin]

开发板为OK3588-C，现在想将相机修改为4lane*2，测试i2c7直接指定data-lanes = <1 2 3 4>;是可以的，另外一个将cam4和cam5的时钟都引出来作为第二个4lane，但是无法使用相机采图，是需要修改cam5的设备树吗？cam4设备树修改如下：

@lin said in 多通道相机设备树设置:

ovti,ov5645

你这个cam5接的是ovti,ov5645，这个我不太懂。
原理上，dts需要跟硬件匹配——用的那个csidphy口，哪几个lane——这个信息dts是要跟硬件原理图匹配的。

[lin]

@veye_xumm cam5支持2lane，cam4也支持2lane，我将cam5的mipi信号线和cam4的全部引出，作为了4lane的一个相机，cam3\4\5都是支持5645的，我使用的i2c3下的所有引脚加上cam5的mipi信号线设置的第二个4lane，我不知道cam5的mipi信号线现在能否可以被相机使用，因为我并没有对cam5以及dphy5做任何修改

[veye_xumm]

@lin 我有一个疑问，你只修改mipi接收端的配置，ov5645配了吗？

[lin]

@veye_xumm 解决了,dphy4不支持4lane
