X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dbb58d0f79207d35f298b619a87fb81dbcae788d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

arm64: dts: hip05: Add L2 cache topology

The Hip05 SoC has four L2 cache for all 16 CPUs, every four cpus
share one L2 cache, add them to the dtsi file so that the cache
