linux-toradex.git/Documentation/hwmon/adt7470, branch v4.9.45 Linux kernel for Apalis and Colibri modules hwmon: (adt7470) Expose PWM frequency to sysfs 2016-09-09T04:34:16+00:00 Joshua Scott joshua.scott@alliedtelesis.co.nz 2016-08-08T01:35:45+00:00 aa18cc911ae2f172429d59169e95726b8e63525c The ADT7470 supports a variety of PWM frequencies. This patch allows the frequency to be configured and viewed through the sysfs entry pwm1_freq.

adt7470: make automatic fan control really work 2009-01-06T23:59:18+00:00 Darrick J. Wong djwong@us.ibm.com 2009-01-06T22:41:34+00:00 89fac11cb3e7c5860c425dba14845c09ccede39d It turns out that the adt7470's automatic fan control algorithm only works when the temperature sensors get updated. This in turn happens only when someone tells the chip to read its temperature sensors. Regrettably, this means that we have to drive the chip periodically. Signed-off-by: Darrick J.
