From 7a51e50582b65bb6ac54e8923470807b5975c6e1 Mon Sep 17 00:00:00 2001 From: Stefan Reinauer Date: Mon, 1 Dec 2008 14:18:57 +0000 Subject: The Winbond Super I/O chips have another indirection of registers. The 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.
