[PATCH v2 6/6] arm64: dts: ti: k3-am62p-j722s-common-main: Assign SRAM to VPU node

From: Brandon Brnich <hidden>
Date: 2026-08-10 20:52:46
Also in: linux-devicetree, lkml
Subsystem: arm/texas instruments k3 architecture, the rest · Maintainers: Nishanth Menon, Vignesh Raghavendra, Tero Kristo, Linus Torvalds

The Wave5 VPU supports connecting to on-chip SRAM through its secondary
AXI interface. This allows temporal buffers to be stored on a per-stream
basis, reducing DDR memory traffic.
