From 300b5f661eebefb8571841b78091343eb87eca54 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Thu, 28 Jul 2022 13:37:47 +0200 Subject: [PATCH] arm64: dts: qcom: sdm845: narrow LLCC address space The Last Level Cache Controller (LLCC) device does not need to access entire LLCC address space. Currently driver uses only hardware info and status registers which both reside in LLCC0_COMMON range (offset 0x30000, size 0x1000). Narrow the address space to allow binding other drivers to rest of LLCC address space.
