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
