Subject: [PATCH v3 1/5] dt-bindings: i3c: mipi-i3c-hci: add Microchip SAMA7D65 compatible
Date: Thu, 12 Mar 2026 09:50:52 +0530	[thread overview]
Message-ID: <20260312042056.309237-2-manikandan.m@microchip.com> (raw)
In-Reply-To: <20260312042056.309237-1-manikandan.m@microchip.com>

Add the microchip,sama7d65-i3c-hci compatible string to the MIPI I3C
HCI binding. The Microchip SAMA7D65 I3C controller is based on the
MIPI HCI specification but requires two clocks, so add a conditional
constraint when this compatible is present.
