Subject: [PATCH net-next v2 07/19] net: phy: mscc: implement generic .handle_interrupt() callback
Date: Sun,  1 Nov 2020 14:51:02 +0200	[thread overview]
Message-ID: <20201101125114.1316879-8-ciorneiioana@gmail.com> (raw)
In-Reply-To: <20201101125114.1316879-1-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.

Also, remove the .did_interrupt() callback since it's not anymore used.

Signed-off-by: Ioana Ciornei <ioana.ciornei@nxp.com>
---
Changes in v2:
 - adjust .handle_interrupt() so that we only take into account the
   enabled IRQs.
