From 8ca7c1608c34aeaed2411af60b3531b2ddf85cc3 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Wed, 5 Sep 2018 12:42:11 -0700 Subject: [PATCH] net: dsa: b53: Add ability to enable/disable port interrupts Some switches expose individual interrupt line(s) for port specific event(s), allow configuring these interrupts at an appropriate time during port_enable/disable callbacks where all port specific resources are known to be set-up and ready for use.
