Hi Heiko and Simon,
I have find out one bug in i2c class. I am using zcu104 revC board which has dts in mainline where i2c1 has i2c mux with some channels. In DT clock-frequency = <400000>; is specified and it is read in i2c_post_probe(). But i2c_mux_bus_drv is also UCLASS_I2C which means that post probe is called for it too. And because clock-frequency property is not there default 100k is used.
I think that is bug and should be fixed. Heiko: Are you aware about this issue?
Simon: I think that make sense to use some flags to skip calling post_probe in this case. Or any suggestion how to fix it would be great.
Thanks, Michal
