Subject: [PATCH RFC 0/2] hwmon: Add RPi PoE HAT fan driver
Date: Sun,  2 Sep 2018 13:20:49 +0200	[thread overview]
Message-ID: <1535887251-29515-1-git-send-email-stefan.wahren@i2se.com> (raw)

This series is an early stage of the hwmon driver for the fan on the
Raspberry Pi Power over Ethernet HAT [1]. At the end this should use a
Device Tree Overlay.

Changes by Stefan based on [2]:
- reformat the downstream patches for submission
- drop reboot notification
- fix remaining checkpatch issues
- add COMPILE_TEST to Kconfig

The driver is mostly copy & paste from pwm-fan, which isn't good. Personally
i see two options:

1) integrate the driver function into the pwm-fan driver (new compatible)
2) implement the core function as a PWM driver and use the pwm-fan driver on top
