Subject: [PATCH hwmon-next v4 0/3] Add support for EMC2305 Fan Speed Controller.
Date: Thu, 23 Jun 2022 19:52:14 +0300 [thread overview]
Message-ID: <20220623165217.59252-1-michaelsh@nvidia.com> (raw)
From: Michael Shych <michaelsh@nvidia.com>
Introduce EMC2305 RPM-based PWM Fan Speed Controller
The EMC2305 is an SMBus compliant fan controller with up to five
controlled PWM fan drivers. All fan drivers are
controlled by a programmable frequency PWM driver and Fan Speed
Control algorithm that operates as a directly PWM-controlled device.
The closed-loop Fan Speed Control algorithm (FSC) has the capability to
detect aging fans and alert the system. It will likewise detect stalled
or locked fans and trigger an interrupt.
EMC2305 offers a clock output so that multiple devices may be chained
and slaved to the same clock source for optimal performance in large
distributed systems.
Patch set includes:
Patch#1 - add support for EMC2301/2/3/5 RPM-based PWM Fan Speed Controller.
Patch#2 - add microchip,emc2306.yaml
Patch#3 - add emc2305.rst into docs.
