Subject: [PATCH v2] media: dt-bindings: dongwoon,dw9714: Fix example implying 1.8V
Date: Wed, 19 Aug 2026 15:46:54 +0200 [thread overview]
Message-ID: <20260819-pp-pro-camera-v2-1-c21652dd388d@ixit.cz> (raw)
From: David Heidelberg <david@ixit.cz>
The datasheet says VDD should be between 2.3 to 4.3V, usually around
2.8V. Correct to prevent confusion and extend description.
Fixes: 2a96b40f366a ("media: dt-bindings: dongwoon,dw9714: convert to dtschema")
Signed-off-by: David Heidelberg <david@ixit.cz>
---
The example implies incorrect voltage, fix it.

Changes in v2:
- Dropped the devices fixes, needs HW owners to address issues or
document state to be understandable.
- Link to v1: https://patch.msgid.link/20260801-pp-pro-camera-v1-0-7b4d90788f9f@ixit.cz
