Subject: [PATCH v3 02/11] arm64: dts: amlogic: Add cache information to the Amlogic SM1 SoC
Date: Fri, 5 Sep 2025 17:27:33 +0530 [thread overview]
Message-ID: <20250905115836.7549-3-linux.amoon@gmail.com> (raw)
In-Reply-To: <20250905115836.7549-1-linux.amoon@gmail.com>
As per S905X3 datasheet add missing cache information to the Amlogic
SM1 SoC. ARM Cortex-A55 CPU uses unified L3 cache instead of L2 cache.
- Each Cortex-A55 core has 32KB of L1 instruction cache available and
32KB of L1 data cache available.
- Along with 256KB Unified L2 cache.
