[PATCH 12/15] dt-bindings: media: addition of stm32mp25 compatible of DCMIPP

From: Alain Volmat
Date: Tue Oct 08 2024 - 07:22:47 EST


Addition of the stm32mp25 compatible for the DCMIPP.
The stm32mp25 distinguish with the stm32mp13 by the fact that:
- supports also csi inputs in addition to parallel inputs
- requires an addition csi clock to be present

The commit also adds access-controllers, an optional property that
allows a peripheral to refer to one or more domain access controller(s).
