From: Maheswara Kurapati Date: Thu, 30 Jun 2022 07:21:13 +0000 (+0200) Subject: hw/arm/aspeed: Add MAX31785 Fan controllers X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2a75e8c390c7e4fd071f51e688524c3dd8014f64;p=qemu.git 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.
