From 2a75e8c390c7e4fd071f51e688524c3dd8014f64 Mon Sep 17 00:00:00 2001 From: Maheswara Kurapati Date: Thu, 30 Jun 2022 09:21:13 +0200 Subject: hw/arm/aspeed: Add MAX31785 Fan controllers Add MAX31785 fan controllers in machines so that the Linux driver populates the sysfs interface. Firework has two MAX31785 Fan controllers at 0x52, and 0x54 on bus 9. Witherspoon has one at 0x52 on bus 3. Rainier has one at 0x52 on bus 7.
