From 88fe301896596da34847871dbdfe261ed1148676 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Fri, 17 Oct 2025 17:58:37 +0200 Subject: [PATCH] media: dt-bindings: nxp,imx8-jpeg: Document optional SRAM support Document optional phandle to mmio-sram, which can describe an SRAM region used for descriptor storage instead of regular DRAM region. Use of SRAM instead of DRAM for descriptor storage may improve bus access pattern and performance.
