Subject: [PATCH] arm64: dts: amlogic: meson-g12b: Fix L2 cache reference for S922X CPUs
Date: Sun, 23 Nov 2025 18:14:10 +0100 [thread overview]
Message-ID: <20251123-fixkhadas-v1-1-045348f0a4c2@baylibre.com> (raw)
The original addition of cache information for the Amlogic S922X SoC
used the wrong next-level cache node for CPU cores 100 and 101,
incorrectly referencing `l2_cache_l`. These cores actually belong to
the big cluster and should reference `l2_cache_b`. Update the device
tree accordingly.
Fixes: e7f85e6c155a ("arm64: dts: amlogic: Add cache information to the Amlogic S922X SoC")
