Subject: [PATCHv2 06/16] vpfe_capture: remove deprecated davinci drivers
Date: Wed, 11 Jan 2023 12:24:08 +0100 [thread overview]
Message-ID: <20230111112418.687882-7-hverkuil-cisco@xs4all.nl> (raw)
In-Reply-To: <20230111112418.687882-1-hverkuil-cisco@xs4all.nl>
The vpfe_capture drivers do not use the vb2 framework for streaming
video, instead they use the old vb1 framework and nobody stepped in to
convert these drivers to vb2.
The hardware is very old, so the decision was made to remove them
altogether since we want to get rid of the old vb1 framework.

- * These SoCs have, in common, a Video Processing Subsystem (VPSS) that
- * consists of a Video Processing Front End (VPFE) for capturing
- * video/raw image data and Video Processing Back End (VPBE) for displaying
- * YUV data through an in-built analog encoder or Digital LCD port. This
- * driver is for capture through VPFE. A typical EVM using these SoCs have
- * following high level configuration.
- *
- * decoder(TVP5146/ YUV/
- * MT9T001) --> Raw Bayer RGB ---> MUX -> VPFE (CCDC/ISIF)
- * data input | |
- * V |
- * SDRAM |
- * V
- * Image Processor
- * |
- * V
- * SDRAM
- * The data flow happens from a decoder connected to the VPFE over a
- * YUV embedded (BT.656/BT.1120) or separate sync or raw bayer rgb interface
- * and to the input of VPFE through an optional MUX (if more inputs are
- * to be interfaced on the EVM). The input data is first passed through
- * CCDC (CCD Controller, a.k.a Image Sensor Interface, ISIF). The CCDC
- * does very little or no processing on YUV data and does pre-process Raw
- * Bayer RGB data through modules such as Defect Pixel Correction (DFC)
- * Color Space Conversion (CSC), data gain/offset etc. After this, data
- * can be written to SDRAM or can be connected to the image processing
- * block such as IPIPE (on DM355 only).
- *
- * Features supported
- * - MMAP IO
- * - Capture using TVP5146 over BT.656
- * - support for interfacing decoders using sub device model
- * - Work with DM355 or DM6446 CCDC to do Raw Bayer RGB/YUV
- * data capture to SDRAM.
- * TODO list
- * - Support multiple REQBUF after open
- * - Support for de-allocating buffers through REQBUF
- * - Support for Raw Bayer RGB capture
- * - Support for chaining Image Processor
- * - Support for static allocation of buffers
- * - Support for USERPTR IO
- * - Support for STREAMON before QBUF
- * - Support for control ioctls
