2019-02-25net: phy: aquantia: add hwmon supportHeiner Kallweit
This adds HWMON support for the temperature sensor and the related alarms on the 107/108/109 chips. This patch is based on work from Nikita and Andrew. I added: - support for changing alarm thresholds via sysfs - move HWMON code to a separate source file to improve maintainability - smaller changes like using IS_REACHABLE instead of ifdef (avoids problems if PHY driver is built in and HWMON is a module) v2: - remove struct aqr_priv - rename header file to aquantia.h v3: - add conditional compiling of aquantia_hwmon.c - improve converting sensor register values to/from long - add helper aqr_hwmon_test_bit Signed-off-by: Nikita Yushchenko <nikita.yoush@cogentembedded.com> Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.
