Subject: [PATCH v6 09/17] arm64: dts: qcom: sc8280xp: Fix the base addresses of LLCC banks
Date: Wed, 18 Jan 2023 20:38:56 +0530	[thread overview]
Message-ID: <20230118150904.26913-10-manivannan.sadhasivam@linaro.org> (raw)
In-Reply-To: <20230118150904.26913-1-manivannan.sadhasivam@linaro.org>

The LLCC block has several banks each with a different base address
and holes in between. So it is not a correct approach to cover these
banks with a single offset/size. Instead, the individual bank's base
address needs to be specified in devicetree with the exact size.
