From 49644e68f472c6480e015253fa4d7448c6cfa2aa Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Thu, 30 May 2019 15:10:06 +0200 Subject: net: phy: add callback for custom interrupt handler to struct phy_driver The phylib interrupt handler handles link change events only currently. However PHY drivers may want to use other interrupt sources too, e.g. to report temperature monitoring events. Therefore add a callback to struct phy_driver allowing PHY drivers to implement a custom interrupt handler.
