Subject: [PATCH net-next v1 4/4] net: phy: mxl-gpy: disable interrupts on GPY215 by default
Date: Fri, 2 Dec 2022 16:12:04 +0100 [thread overview]
Message-ID: <20221202151204.3318592-5-michael@walle.cc> (raw)
In-Reply-To: <20221202151204.3318592-1-michael@walle.cc>
The interrupts on the GPY215B and GPY215C are broken and the only viable
fix is to disable them altogether. There is still the possibilty to
opt-in via the device tree.
