Want to change the i2c frequency

hello

using the socfpga_linux(https://github.com/altera-opensource/linux-socfpga/tree/socfpga-4.0)

I would want to change the frequency of i2c device to 100khz below
However, this source is taking limited to 100khz and 400khz

To fix it, what should I do?

hi!!
So for the i2c interface you just have two speed rates 10kHz and 400kHz!
You can configure the interface speed @ register ic_con bit 2:1
