[PATCH v2 0/2] media: m2m-deinterlace: add device-tree support

From: Matthew Majewski
Date: Fri Feb 14 2025 - 18:18:34 EST


Hello all, this patch series adds device-tree support for the generic
m2m-deinterlace driver.

A specific dma controller channel can now be provided to the driver
via the dt, but the driver still supports the original dma query if an
of_node is not present. This should preserve backwards compatibility
with platform drivers that directly instantiate the device.

Probing the m2m-deinterlace device via device-tree was tested on the
BeagleBone Black with an m2m-appropriate edma channel.

Changes From v1 [1]:
- [PATCH 1/2] media: dt-bindings: Add dt bindings for m2m-deinterlace
- clarify device description and commit message for dt bindings
- correct format error reported by yamllint for dt bindings
- [PATCH 2/2] media: m2m-deinterlace: add device-tree support
- no changes
