Subject: [PATCH v5 7/8] arm64: dts: ti: k3-am64x-sk: Enable eQEP
Date: Wed, 12 Jun 2024 08:55:37 -0500	[thread overview]
Message-ID: <20240612135538.2447938-8-jm@ti.com> (raw)
In-Reply-To: <20240612135538.2447938-1-jm@ti.com>

There are 3 instances of eQEP on AM64x. Only EQEP0 signals
can be routed to the user expansion so enable only EQEP0
in k3-am642-sk.dts.
