[PATCH v3 0/4] Add SRAM Nodes for VPU

From: Brandon Brnich

Date: Mon Sep 21 2026 - 14:54:41 EST


Hello All,

This series is responsible for adding the SRAM nodes for the Wave5 VPU to
use. First patch is responsible for carving out the SRAM pool from
main_navss that the VPU on J721s2 will then reference.

The last 2 patches use the existing oc_sram pool already found in the
relevant device trees.


Changes since v2:

- Removed j784s4 since there are two vpu instances, need to find
another SRAM pool so both can get full benefit of B/W savings

Changes since v1:

- properly updates the nodename in the first two patches to pass
dtbs_check.

Best,
Brandon
