+Subject: [PATCH] net: phy: realtek: HWMON support for standalone versions of
+ RTL8221B and RTL8251
+
+HWMON support has been added for the RTL8221/8251 PHYs integrated together
+with the MAC inside the RTL8125/8126 chips. This patch extends temperature
+reading support for standalone variants of the mentioned PHYs.
+
+I don't know whether the earlier revisions of the RTL8226 also have a
+built-in temperature sensor, so they have been skipped for now.
+
+Tested on RTL8221B-VB-CG.
