From e495a11e0a97eee09c5ae4a08b72d0b5d9376da5 Mon Sep 17 00:00:00 2001 From: Daniel Perez-Zoghbi Date: Wed, 10 Jan 2024 18:12:41 -0800 Subject: [PATCH] ARM: dts: qcom: Use non-coherent on QCE CB Switch to using dma-noncoherent context bank on qce. Dma-coherent was causing stale data to be read. SS confirmed that this was fixed by using dma-noncoherent. Using explicit dma-noncoherent because the parent node, qcedev, is dma-coherent, and the context bank would inherit it.
