Subject: [PATCH 1/2] hwmon: (aspeed-pwm-tacho) reduce fan_tach period
Date: Tue, 20 Jun 2017 18:14:48 -0700 [thread overview]
Message-ID: <20170621011448.25296-1-venture@google.com> (raw)
Reduce the fan_tach period such that the fan controller uses a shorter
period to measure the rpm.
Testing: This was tested on an ast2400 sitting on a quanta-q71l.
