Subject: arm64: dts: mt6795: Add complete CPU caches information
X-Git-Tag: v6.3-rc1~202^2~24^2~41
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c5f30727ce68da227cfba95450a358cbd75e814c;p=thirdparty%2Fkernel%2Flinux.git

arm64: dts: mt6795: Add complete CPU caches information

This SoC's AP subsystem has 8x Cortex-A53 CPUs, specifically,
four CPUs per cluster, with two CPU clusters.

Each CPU has:
 - A 32KB I-cache, 2-way set associative;
 - A 32KB D-cache, 4-way set associative.

Each cluster has a unified 1MB L2 cache, 16-way set associative.

With that in mind, add the appropriate properties needed to specify the
caches information for this SoC, which will now be correctly exported
to sysfs.
