[PATCH v2 1/2] media: dt-bindings: Add dt bindings for m2m-deinterlace device
From: Matthew Majewski
Date: Fri Feb 14 2025 - 18:18:53 EST
Create a new yaml schema file to describe the device tree bindings for
generic m2m-deinterlace device.
This device is supported on any hardware that provides a MEM_TO_MEM
capable dma channel with interleaved trasfer support. Device tree
bindings are for providing appropriate dma channel to device.

+description: |-
+ A generic memory2memory device for deinterlacing video using dmaengine. It can
+ convert between interlaced buffer formats and can convert interlaced to
+ progressive using a simple line-doubling algorithm. This device can be used on
+ any hardware that provides a MEM_TO_MEM capable dma controller that supports
+ interleaved transfers.
