Subject: [PATCH v5 1/5] dt-bindings: i3c: mipi-i3c-hci: add Microchip SAMA7D65 compatible
Date: Tue, 5 May 2026 12:43:23 +0530 [thread overview]
Message-ID: <20260505071327.125787-2-manikandan.m@microchip.com> (raw)
In-Reply-To: <20260505071327.125787-1-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.
Signed-off-by: Manikandan Muralidharan <manikandan.m@microchip.com>
---
Changes in v5:
- drop min/maxItems around clock
- use else clause
- cosmetic fixes
Changes in v4:
- Define and describe the clock in the top-level properties
