From 067161281f428aa7c6e153e06aab7b5fe1ed1e98 Mon Sep 17 00:00:00 2001 From: "Maciej S. Szmigiero" Date: Thu, 15 Dec 2016 23:52:36 +0100 Subject: [PATCH] watchdog: it87_wdt: add IT8620E ID This adds IT8620E chip ID to it87_wdt driver. Such chip is often found on current Gigabyte motherboards, it is allegedly custom made for this manufacturer. Upon testing it looks like it has a 16-bit timer and cannot be reset via game port (only via CIR), so it is similar to IT87{18,20,21,28,83} chips. Tested on GA-F2A88XM-HD3P board.
