Introduce a new vimc-input entity to simulate a color frame source in the
Virtual Media Controller (VIMC) pipeline. This entity outputs RGB888 frames
and allows testing of pipelines that start from a pre-processed RGB/YUV
source instead of a raw Bayer sensor.
The patch adds vimc-input.c with basic pad operations for format
enumeration, get/set, and stream enable/disable handlers. The entity is
registered in the VIMC core configuration, replacing the previous temporary
use of vimc-sensor. Frame generation is not yet implemented and remains a
TODO for future work.
This change enables link validation and format negotiation for the
RGB/YUV input path, paving the way for software frame injection and
test-pattern generation.

Sorry for the delay - these four patches especially this one add
I see 4 patches - are they dependent then gerenrate a sries
with cover letter explaining the changes you are making.
thanks,

even though all 4 patches are part of vimc driver,
these are independent patches
Independent in the sense that they can be applied and tested
independently?
Yes. all 4 patches can be applied and test independently
new features/functionality to to vimc.
These require updates - Documentation/admin-guide/media/vimc.rst
Please include the documentation patch - please send these as
series 4 patches + doc patch as a series.
The changes look okay to me.
thanks,
