[PATCH] hwmon: Add PEC support to the lm90 driver
Add PEC support to the lm90 driver. Only the ADM1032 chip supports it, and in a rather tricky way, which is why this patch comes with documentation reinforcements. At least, this demonstrates that the new PEC support logic in i2c-core can properly deal with chips with partial PEC support. As enabling PEC causes a significant performance drop, it can be disabled through a sysfs file (unsurprisingly named "pec").
