Hi Peng/all,
Observed an issue while setting the bus on mxc_i2c driver addr = dev_get_addr(bus); is getting failed to get invalid address.

Any help? did you tested on any board?
It works well on i.MX6ULL 14x14 EVK board. " => i2c bus Bus 0: i2c@021a0000 Bus 1: i2c@021a4000 => i2c dev 0 Setting bus to 0 i2c bus 0 at 35258368, no gpio pinctrl state. => i2c probe Valid chip addresses: 0E 1E => i2c dev 1 Setting bus to 1 i2c bus 1 at 35274752, no gpio pinctrl state. => i2c probe Valid chip addresses: 1A => i2c bus Bus 0: i2c@021a0000 (active 0) 0e: generic_e, offset len 1, flags 0 1e: generic_1e, offset len 1, flags 0 Bus 1: i2c@021a4000 (active 1) 1a: generic_1a, offset len 1, flags 0 "
Add alias, and have a try. aliases { i2c0 = &i2c1; i2c1 = &i2c2; };
Regards, Peng.
thanks!
