Subject: [PATCH v2 0/2] net: dsa: Move temperature sensor code into PHY.
Date: Fri, 20 Jan 2017 01:37:48 +0100	[thread overview]
Message-ID: <1484872670-32585-1-git-send-email-andrew@lunn.ch> (raw)

Marvell Ethernet switches contain a temperature sensor. There appears
to be one sensor, which is shared by each of the internal PHYs. Each
PHY has independent registers to read this sensor, and to set a limit
for when an alarm should be raised.

Some Marvell discrete PHY also have the same sensor and registers.
Moving the HWMON code from DSA into the PHY makes the sensor available
in discrete PHYs, and removes the layering violation, the switch
driver poking around in PHY registers.

While moving the code into the PHY driver, it has been re-written to
use the new HWMON APIs.

v2:

Better Cover note explaining one sensor, but multiple independent
registers

Simply error checking.
