Subject: [PATCH v2 06/10] dt-bindings: display: imx: Add bindings for i.MX94 DCIF
Date: Wed, 16 Jul 2025 11:15:10 +0300	[thread overview]
Message-ID: <20250716081519.3400158-7-laurentiu.palcu@oss.nxp.com> (raw)
In-Reply-To: <20250716081519.3400158-1-laurentiu.palcu@oss.nxp.com>

DCIF is the i.MX94 Display Controller Interface which is used to
drive a TFT LCD panel or connects to a display interface depending
on the chip configuration.
