From ec2f548e1a92f49f765e2bce14ceed34698514fc Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam manivannan.sadhasivam@linaro.org Date: Tue, 31 Dec 2024 18:32:23 +0530 Subject: [PATCH] arm64: dts: qcom: sa8775p: Fix the size of 'addr_space' regions
For both the controller instances, size of the 'addr_space' region should be 0x1fe00000 as per the hardware memory layout.
Otherwise, endpoint drivers cannot request even reasonable BAR size of 1MB.
