Subject: [PATCH v6 0/2] hwmon: Add NPCM7xx PWM and Fan driver support
Date: Thu, 28 Jun 2018 14:46:44 +0300	[thread overview]
Message-ID: <20180628114646.343734-1-tmaimon77@gmail.com> (raw)

This patch set adds Pulse Width Modulation (PWM) and Fan tacho
support for the Nuvoton NPCM750/730/715/705 Baseboard Management 
Controller (BMC).

The Nuvoton BMC NPCM750/730/715/705 has two identical PWM controller 
modules, each module has four PWM controller outputs and eight identical 
Fan controller modules, each module has two Fan controller inputs.

The hwmon driver provides sysfs entries through which the user can
configure and get the duty cycle between 0 (disable the specific PWM)
to 255 of particular PWM output port.

The driver support cooling device creation, that could be bound
to a thermal zone for the thermal control.

The NPCM750 PWM and Fan driver tested on NPCM750 evaluation board.
