From 7d885863e716757553197687f304da1f538f61e1 Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Mon, 9 Jan 2023 13:30:12 +0100 Subject: net: phy: allow a phy to opt-out of interrupt handling Until now, it is not possible for a PHY driver to disable interrupts during runtime. If a driver offers the .config_intr() as well as the .handle_interrupt() ops, it is eligible for interrupt handling. Introduce a new flag for the dev_flags property of struct phy_device, which can be set by PHY driver to skip interrupt setup and fall back to polling mode. At the moment, this is used for the MaxLinear PHY which has broken interrupt handling and there is a need to disable interrupts in some cases.
