Subject: [PATCH v3 10/10] arm64: dts: uniphier: Add L2 cache node
Date: Tue, 13 Sep 2022 13:23:21 +0900 [thread overview]
Message-ID: <20220913042321.4817-11-hayashi.kunihiko@socionext.com> (raw)
In-Reply-To: <20220913042321.4817-1-hayashi.kunihiko@socionext.com>
Add a L2 cache node referenced from CPU nodes as the missing cache hierarchy
information because the following warning was issued.
cacheinfo: Unable to detect cache hierarchy for CPU 0
Early cacheinfo failed, ret = -2
