I2C muxes that have the slave devices with same address are falling into the below problem. VCK190 system controller (SC) - zynqmp-e-a2197-00-revA.dts I2C1 (0xff030000) -> Mux1 (@0x74) -> Channel 3 -> 0x50 I2C1 (0xff030000) -> Mux2 (@0x75) -> Channel 0 -> 0x50 1. SC accesses I2C1 - Mux1 (0x74) - Channel 3 and then 2. SC accesses I2C1 - Mux2 (0x75) - Channel 0. Now it results in 2 slave devices with same address (0x50) on the I2C bus, making the communication un-reliable. When ' i2c-mux-idle-disconnect' is in DT, after '1', the Mux channel output is disconnected, making none of the channels available to the I2C1. So, there is no question of having the same addressed slave (0x50) present on the bus when we are doing '2'. Same pattern is seen in below two boards also.
