From 678e05a0a3a42fd53250844040c74a7c6bf9de92 Mon Sep 17 00:00:00 2001 From: Mayank Rana Date: Mon, 19 Apr 2021 15:49:40 -0700 Subject: [PATCH] ARM: dts: msm: Reduce USB IOVA address size by size of LLCC TCM memory This change reduces USB IOMMU address size by size of LLCC TCM memory (i.e. 128KB). This simplified allowing usage of DDR or LLCC TCM memory selection with USB RMNET IN buffer and need of changing anything with IPA side geometry fastmap mapping.
