Subject: [PATCH v13 01/15] media: uapi: Add MEDIA_BUS_FMT_RGB202020_1X60 format code
Date: Tue, 11 Nov 2025 16:15:45 +0000 [thread overview]
Message-ID: <20251111-c55-v13-1-3dc581355e3a@ideasonboard.com> (raw)
In-Reply-To: <20251111-c55-v13-0-3dc581355e3a@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.

time slots per pixel clock, on three (18-bit) or four (24-bit) or five (30-bit)
differential data pairs at the same time. The remaining bits are used
