From 25497b7f0bd90706dd697523f3e9e074641632b5 Mon Sep 17 00:00:00 2001 From: Ioana Ciornei Date: Mon, 23 Nov 2020 17:38:05 +0200 Subject: [PATCH] net: phy: icplus: implement generic .handle_interrupt() callback In an attempt to actually support shared IRQs in phylib, we now move the responsibility of triggering the phylib state machine or just returning IRQ_NONE, based on the IRQ status register, to the PHY driver. Having 3 different IRQ handling callbacks (.handle_interrupt(), .did_interrupt() and .ack_interrupt() ) is confusing so let the PHY driver implement directly an IRQ handler like any other device driver. Make this driver follow the new convention.
