Register I2C devices on different channels to pca9548

Hi,

We used pca9548 to connect many devices. For example, channel 3 connect an EEPROM and channel 4 connect tmp421 sensor.
Currently, we can see two device nodes for channel 3 and channel 4. We hope tmp421 sensor as a device node in system. Do you know how to register I2C devices on different channels to pca9548 by i2c_new_device()?
Thanks.

Look at the following pages:

On my board, main CPU is intel x86 family, it don't support device tree.

Dose other plan can fix my problem?

Thanks.
