Subject: Experimental support for IT8607E
X-Git-Tag: v1.0~55
X-Git-Url: https://git.sur5r.net/?p=groeck-it87;a=commitdiff_plain;h=c7994710d1761d5bb91cef865722493bceb39d3e

Experimental support for IT8607E

Assume for now that in5 and in6 are supported, and that fan control
is standard (unlike IT8603E).
