Subject: [PATCH AUTOSEL 5.4 01/13] arm64: dts: qcom: sdm845: narrow LLCC address space
Date: Tue, 11 Oct 2022 10:53:26 -0400 [thread overview]
Message-ID: <20221011145338.1624591-1-sashal@kernel.org> (raw)
From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
[ Upstream commit 300b5f661eebefb8571841b78091343eb87eca54 ]
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.
