Subject: [PATCH 2/6] media: v4l: Add definition for bayered IR formats
Date: Tue, 27 Apr 2021 14:06:57 +0200	[thread overview]
Message-ID: <20210427120701.21809-3-m.felsch@pengutronix.de> (raw)
In-Reply-To: <20210427120701.21809-1-m.felsch@pengutronix.de>

Add special 8/12bit bayer media bus format for the OnSemi AR0237IR
camera sensor [1]. OnSemi calls this format RGB-IR, the pixel array
with the interleaved IR pixels looks like:

        |  G |  R |  G |  B | ...
        +----+----+----+----+---
        | IR |  G | IR |  G | ...
        +----+----+----+----+---
        |  G |  B |  G |  R | ...
        +----+----+----+----+---
        | IR |  G | IR |  G | ...
        +----+----+----+----+---
        | .. | .. | .. | .. | ..
