[PATCH 06/20] arm64: dts: Update cache properties for exynos

[Pierre Gondois]

The DeviceTree Specification v0.3 specifies that the cache node
'compatible' and 'cache-level' properties are 'required'. Cf.
s3.8 Multi-level and Shared Cache Nodes

The recently added init_of_cache_level() function checks
these properties. Add them if missing.

Not sure if this need to be documented in schema/yaml file as well or
already part of schema?

Now dropped. I understand this is the intention/request of v2.

When resending be sure to use proper subject prefixes.

[Pierre Gondois]

Hello Krzysztof,

This patch and [1] were dropped after a bad patch management from my part.
v1 and v2 are identical, but [2] lead to the 2 patches to be removed.
Not willing to worsen the situation, I wanted to wait a bit before getting
back to these 2 patches and let them be removed.
Would it be possible to take back these 2 patches ?

Regards,
Pierre
