From 95864f27330674c970c84b81ae791182de150b0f Mon Sep 17 00:00:00 2001 From: Sibi Sankar Date: Tue, 17 Jan 2023 14:28:32 +0530 Subject: [PATCH] dt-bindings: remoteproc: qcom,sc7180-mss-pil: Update memory-region The dynamic memory region used for metadata authentication would still be a part of the kernel mapping and any access to this region by the application processor after assigning it to the remote Q6 will result in a XPU violation. This is fixed by using a no-map carveout instead. Update the bindings to reflect the addition of the new modem metadata carveout on SC7180 SoC.
