From f3c165459c5189b7b469e3b86107ee8819c93774 Mon Sep 17 00:00:00 2001 From: Arun Ramadoss Date: Fri, 2 Sep 2022 16:02:08 +0530 Subject: net: dsa: microchip: add reference to ksz_device inside the ksz_port struct ksz_port doesn't have reference to ksz_device as of now. In order to find out from which port interrupt has triggered, we need to pass the struct ksz_port as a host data. When the interrupt is triggered, we can get the port from which interrupt triggered, but to identify it is phy interrupt we have to read status register. The regmap structure for accessing the device register is present in the ksz_device struct. To access the ksz_device from the ksz_port, the reference is added to it with port number as well.
