From 6719e2be0fcfa404a885e9bf80c7e1139adf0e39 Mon Sep 17 00:00:00 2001 From: Ioana Ciornei Date: Mon, 23 Nov 2020 17:38:07 +0200 Subject: [PATCH] net: phy: meson-gxl: 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.
