Subject: [PATCH v3 0/4] Add SRAM Nodes for VPU
Date: Mon, 21 Sep 2026 13:48:46 -0500	[thread overview]
Message-ID: <20260921184850.3810018-1-b-brnich@ti.com> (raw)

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
