The Winbond Super I/O chips have another indirection of registers. The

Browse Source 
hwmon has generic registers and banked registers, mostly temperature
handling, and SMI/GPIO stuff.

Not all LDNs are switched via register offset 0x07, make it a parameter.
  
Add support for dumping the hardware monitor of Winbond W83627THF/THG
parts with the -e option.
