Subject: [PATCH v4] media: dt-bindings: Correct camss supply description
Date: Mon, 22 Dec 2025 15:16:05 +0100 [thread overview]
Message-ID: <20251222-docs-camss-fixes-v4-1-914a4e5f7822@ixit.cz> (raw)
From: David Heidelberg <david@ixit.cz>
Usually, the supply is around 1.2 V, not 1.8 V, and also correct wording.
Signed-off-by: David Heidelberg <david@ixit.cz>

Eventually, if more changes would be requested, would make sense someone
from Qualcomm to follow-up on these, as I don't have schematics,
documentation or also no access to the internal resources.
Thank you
