H A D | t8103.dtsi | 9ecb7a4b Tue Dec 06 16:38:46 CST 2022 Janne Grunau <j@jannau.net> arm64: dts: apple: Add t8103 L1/L2 cache properties and nodes
The t8103 CPU nodes are missing the cache hierarchy information. The cache hierarchy on Arm can not be detected and needs to be described in DT. The OS scheduler can make use of this information for scheduling decisions.
The cache size information is based on various articles about the processors. There's also an L3 system level cache (SLC). It's not described here because SLCs typically have some MMIO interface which would need to be described.
Based on Rob Herring's patch adding cache properties and nodes for t600x.
