Hi,

For implementing "early boot late attach" to our custom board for VSDK304, we need to enable i2c2 ~ i2c5 in uboot or ipu2 before loading Linux. How to enable i2c 2~5 in ipu2?

Thanks.

Hi Chieh,

What is your motivation of enabling i2c from the IPU2 software? Are all the devices connected to that bus only ever used from IPU2.

regards

Suman

Because we need to enable i2c to control capture/display device before loading linux kernel in "early boot late attach" mode. One solution is to do it in uboot, another one is to do it in ipu2.

We successfully enabled i2c in uboot recently. So we don't need to enable it in ipu2 any more. Thanks.

BR,

Jeff
