I published lsi2c and libi2cdev on github if anyone is interested in trying out the new i2c bus tools. https://github.com/costad2/i2cdev Any feedback and contribution is greatly appreciated EXAMPLE: [root@linux ~]# lsi2c I2C Adapters: bus: i2c-0 path: 0 type: i2c name: MPC adapter at 0xffe03000 bus: i2c-2 path: 0:0.0 type: mux name: i2c-0-mux (chan_id 0) bus: i2c-3 path: 0:0.1 type: mux name: i2c-0-mux (chan_id 1) bus: i2c-4 path: 0:0.2 type: mux name: i2c-0-mux (chan_id 2) bus: i2c-5 path: 0:0.3 type: mux name: i2c-0-mux (chan_id 3) bus: i2c-6 path: 0:0.4 type: mux name: i2c-0-mux (chan_id 4) bus: i2c-7 path: 0:0.5 type: mux name: i2c-0-mux (chan_id 5) bus: i2c-8 path: 0:0.6 type: mux name: i2c-0-mux (chan_id 6) bus: i2c-9 path: 0:0.7 type: mux name: i2c-0-mux (chan_id 7) bus: i2c-1 path: 1 type: i2c name: MPC adapter at 0xffe03100 bus: i2c-10 path: 1:0.0 type: mux name: i2c-1-mux (chan_id 0) bus: i2c-11 path: 1:0.1 type: mux name: i2c-1-mux (chan_id 1) bus: i2c-18 path: 1:0.1:0.0 type: mux name: i2c-11-mux (chan_id 0) bus: i2c-12 path: 1:0.2 type: mux name: i2c-1-mux (chan_id 2) bus: i2c-32 path: 1:0.2:0.0 type: mux name: i2c-12-mux (chan_id 0) bus: i2c-33 path: 1:0.2:0.0:0.0 type: mux name: i2c-32-mux (chan_id 0) bus: i2c-34 path: 1:0.2:0.0:0.1 type: mux name: i2c-32-mux (chan_id 1) bus: i2c-35 path: 1:0.2:0.0:0.2 type: mux name: i2c-32-mux (chan_id 2) bus: i2c-36 path: 1:0.2:0.0:0.3 type: mux name: i2c-32-mux (chan_id 3) bus: i2c-37 path: 1:0.2:0.0:0.4 type: mux name: i2c-32-mux (chan_id 4) bus: i2c-38 path: 1:0.2:0.0:0.5 type: mux name: i2c-32-mux (chan_id 5) bus: i2c-39 path: 1:0.2:0.0:0.6 type: mux name: i2c-32-mux (chan_id 6) bus: i2c-40 path: 1:0.2:0.0:0.7 type: mux name: i2c-32-mux (chan_id 7) bus: i2c-13 path: 1:0.3 type: mux name: i2c-1-mux (chan_id 3) bus: i2c-23 path: 1:0.3:0.0 type: mux name: i2c-13-mux (chan_id 0) bus: i2c-24 path: 1:0.3:0.0:0.0 type: mux name: i2c-23-mux (chan_id 0) bus: i2c-25 path: 1:0.3:0.0:0.1 type: mux name: i2c-23-mux (chan_id 1) bus: i2c-26 path: 1:0.3:0.0:0.2 type: mux name: i2c-23-mux (chan_id 2) bus: i2c-27 path: 1:0.3:0.0:0.3 type: mux name: i2c-23-mux (chan_id 3) bus: i2c-28 path: 1:0.3:0.0:0.4 type: mux name: i2c-23-mux (chan_id 4) bus: i2c-29 path: 1:0.3:0.0:0.5 type: mux name: i2c-23-mux (chan_id 5) bus: i2c-30 path: 1:0.3:0.0:0.6 type: mux name: i2c-23-mux (chan_id 6) bus: i2c-31 path: 1:0.3:0.0:0.7 type: mux name: i2c-23-mux (chan_id 7) bus: i2c-14 path: 1:0.4 type: mux name: i2c-1-mux (chan_id 4) bus: i2c-19 path: 1:0.4:0.0 type: mux name: i2c-14-mux (chan_id 0) bus: i2c-15 path: 1:0.5 type: mux name: i2c-1-mux (chan_id 5) bus: i2c-20 path: 1:0.5:0.0 type: mux name: i2c-15-mux (chan_id 0) bus: i2c-16 path: 1:0.6 type: mux name: i2c-1-mux (chan_id 6) bus: i2c-21 path: 1:0.6:0.0 type: mux name: i2c-16-mux (chan_id 0) bus: i2c-17 path: 1:0.7 type: mux name: i2c-1-mux (chan_id 7) bus: i2c-22 path: 1:0.7:0.0 type: mux name: i2c-17-mux (chan_id 0) Count: 30 [root@linux ]# lsi2c -d I2C Devices: bus=0 type=i2c bus_path=0 address=0x70 name=pca9548 driver=pca954x bus=6 type=mux bus_path=0:0.4 address=0x68 name=ds1339 driver=rtc-ds1307 bus=1 type=i2c bus_path=1 address=0x74 name=pca9548 driver=pca954x bus=11 type=mux bus_path=1:0.1 address=0x73 name=pca9541 driver=pca9541 bus=12 type=mux bus_path=1:0.2 address=0x7e name=pca9541 driver=pca9541 bus=32 type=mux bus_path=1:0.2:0.0 address=0x71 name=pca9547 driver=pca954x bus=13 type=mux bus_path=1:0.3 address=0x7e name=pca9541 driver=pca9541 bus=23 type=mux bus_path=1:0.3:0.0 address=0x71 name=pca9547 driver=pca954x bus=14 type=mux bus_path=1:0.4 address=0x73 name=pca9541 driver=pca9541 bus=15 type=mux bus_path=1:0.5 address=0x73 name=pca9541 driver=pca9541 bus=16 type=mux bus_path=1:0.6 address=0x73 name=pca9541 driver=pca9541 bus=17 type=mux bus_path=1:0.7 address=0x73 name=pca9541 driver=pca9541 Count: 12 -- - Danielle Costantino -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
