Subject: Re: [PATCH v4 00/14] media: stm32: dcmipp: add support for MP2x pixel pipes
Date: Thu, 20 Aug 2026 09:34:00 +0200 [thread overview]
Message-ID: <aoat6DXYX1z3euI2@gnbcxd0016.gnb.st.com> (raw)
In-Reply-To: <20260820-stm32-dcmipp-pixel-pipes-support-v4-0-d212eb4e3792@foss.st.com>
Hi,
please find below the result of v4l2-compliance -s -dx calls on all 3
pipes (dump (0), main (1), aux (2)).
Prior to each call, proper media-ctl calls are done in order to perform
the correct routing for each use-case.
