55Usage Notes
56-----------
57
58This driver does not probe for PMBus devices. You will have
59to instantiate devices explicitly.
60
61Example: the following commands will load the driver for an PXE1610
Mauro Carvalho Chehab899df7b2019-07-22 08:07:45 -030062at address 0x70 on I2C bus #4::
Vijay Khemka37ab3562019-05-30 16:11:57 -070063
Mauro Carvalho Chehab899df7b2019-07-22 08:07:45 -030064 # modprobe pxe1610
65 # echo pxe1610 0x70 > /sys/bus/i2c/devices/i2c-4/new_device
Vijay Khemka37ab3562019-05-30 16:11:57 -070066
67It can also be instantiated by declaring in device tree
