Subject: [PATCH v2 04/15] net: phy: adin: add support for interrupts
Date: Thu, 8 Aug 2019 15:30:15 +0300	[thread overview]
Message-ID: <20190808123026.17382-5-alexandru.ardelean@analog.com> (raw)
In-Reply-To: <20190808123026.17382-1-alexandru.ardelean@analog.com>

This change adds support for enabling PHY interrupts that can be used by
the PHY framework to get signal for link/speed/auto-negotiation changes.
