Subject: [PATCH 1/2] hwmon: (nct6775) Fix temperature sources for NCT6796D
Date: Fri, 14 Sep 2018 09:32:53 -0700	[thread overview]
Message-ID: <1536942774-23738-1-git-send-email-linux@roeck-us.net> (raw)

The following kernel log message is reported for the nct6775 driver
on ASUS WS X299 SAGE.

nct6775: Found NCT6796D or compatible chip at 0x2e:0x290
nct6775 nct6775.656: Invalid temperature source 11 at index 0,
			source register 0x100, temp register 0x73
nct6775 nct6775.656: Invalid temperature source 11 at index 2,
			source register 0x300, temp register 0x77
nct6775 nct6775.656: Invalid temperature source 11 at index 3,
			source register 0x800, temp register 0x79
nct6775 nct6775.656: Invalid temperature source 11 at index 4,
			source register 0x900, temp register 0x7b

A recent version of the datasheet lists temperature source 11 as reserved.
However, an older version of the datasheet lists temperature sources 10
and 11 as supported virtual temperature sources. Apparently the older
version of the datasheet is correct, so list those temperature sources
as supported.
