Subject: [PATCH 1/5] media: uapi: Add MEDIA_BUS_FMT_RGB202020_1X60 format code
Date: Wed, 31 Jan 2024 16:47:05 +0000	[thread overview]
Message-ID: <20240131164709.810587-2-dan.scally@ideasonboard.com> (raw)
In-Reply-To: <20240131164709.810587-1-dan.scally@ideasonboard.com>

The Mali-C55 ISP by ARM requires 20-bits per colour channel input on
the bus. Add a new media bus format code to represent it.

 On LVDS buses, usually each sample is transferred serialized in seven
 time slots per pixel clock, on three (18-bit) or four (24-bit)
 differential data pairs at the same time. The remaining bits are used
