MDIO/PHY library
----------------
functions such as of_get_phy_mode(), of_phy_connect() are also used to query
per-port PHY specific details: interface connection, MDIO bus location etc..
-HWMON
------
-
-Some switch drivers feature internal temperature sensors which are exposed as
-regular HWMON devices in /sys/class/hwmon/.
-
Driver development
==================
BR_STATE_DISABLED and propagating changes to the hardware if this port is
disabled while being a bridge member
-Hardware monitoring
--------------------
-
-These callbacks are only available if CONFIG_NET_DSA_HWMON is enabled:
-
-- get_temp: this function queries the given switch for its temperature
-
-- get_temp_limit: this function returns the switch current maximum temperature
- limit
-
-- set_temp_limit: this function configures the maximum temperature limit allowed
-
-- get_temp_alarm: this function returns the critical temperature threshold
- returning an alarm notification
-
-See Documentation/hwmon/sysfs-interface for details.
