Add two meta formats for PiSP FE: V4L2_META_FMT_RPI_FE_CFG and V4L2_META_FMT_RPI_FE_STATS. The former is used to provide configuration for the FE and the latter is used to read the statistics from the FE.

Raspberry Pi PiSP Front End configuration format
|
|
================================================
|
|
|
|
The Raspberry Pi PiSP Front End image signal processor is configured by
|
|
userspace by providing a buffer of configuration parameters to the
|
|
`rp1-cfe-fe-config` output video device node using the
|
|
:c:type:`v4l2_meta_format` interface.
|
|
|
|
The `Raspberry Pi PiSP technical specification
|
|
<https://datasheets.raspberrypi.com/camera/raspberry-pi-image-signal-processor-specification.pdf>`_
|
|
provide detailed description of the Front End configuration and programming
|
|
model.

Raspberry Pi PiSP Front End statistics format
|
|
=============================================
|
|
|
|
The Raspberry Pi PiSP Front End image signal processor provides statistics data
|
|
by writing to a buffer provided via the `rp1-cfe-fe-stats` capture video device
|
|
node using the
|
|
:c:type:`v4l2_meta_format` interface.
