Subject: [PATCH RESEND net-next 17/18] net: phy: adin: implement generic .handle_interrupt() callback
Date: Fri, 13 Nov 2020 18:52:25 +0200 [thread overview]
Message-ID: <20201113165226.561153-18-ciorneiioana@gmail.com> (raw)
In-Reply-To: <20201113165226.561153-1-ciorneiioana@gmail.com>
From: Ioana Ciornei <ioana.ciornei@nxp.com>
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.
