From 2c6cb6c557858672cafb6a5dc89a1df993420831 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Thu, 2 Dec 2021 21:58:25 -0800 Subject: hwmon: (lm90) Add support for ON Semiconductor NCT214 and NCT72 NCT214 and NCT72 are compatible to ADT7461/ADT7461A but have full PEC (packet error checking) support. PEC support is undocumented. Both chips support the undocumented secondary chip and manufacturer ID registers at 0x3e and 0x3f, and return 0x61 as chip ID. Use this information to improve the accuracy of chip detection code.
