Hi, The main_i2c0 missed the ioexpander present on the SOM itself to control muxes to route signals to CPB connectors. The main_i2c1 of J7200 is _not_ connected to the i2c1 of CPB, it is connected to i2c3, so the devices on the CPB's i2c1 bus are not avalible, but the ones on the CPB i2c3 are available under the main_i2c1. Add nice line names at the same time to these.
