[PATCH 4/4] remoteproc: k3-dsp: add compatible string for j722s C7XV DSP

From: Hari Nagalla

Date: Thu Feb 12 2026 - 19:12:48 EST


J722S uses the C7XV DSP based deep learning engine similar to AM62A,
but the reset and module enable integration in the SoC is little
different. It does not have a local reset from power state controller.
So, add a new compatible string to distinguish this difference.
For these DSP core variants 'prepare' operation is not needed before
loading the firmware. The module level main reset is released during
'start' operation, i.e after firmware load.
