Subject: [PATCH 2/8] dt-bindings: display: ti, am65x-dss: Add IO CTRL property for AM625 OLDI
Date: Tue, 19 Jul 2022 13:38:39 +0530	[thread overview]
Message-ID: <20220719080845.22122-3-a-bhatia1@ti.com> (raw)
In-Reply-To: <20220719080845.22122-1-a-bhatia1@ti.com>

Add am625-io-ctrl dt property to provide access to the control MMR
registers for the OLDI TXes.

These registers are used to control the power input to the OLDI TXes as
well as to configure them in the Loopback test mode.

The MMR IO controller device has been updated since the AM65x SoC and
hence a newer property is needed to describe the one in AM625 SoC.
