Subject: [PATCH 00/20] Update cache properties for arm64 DTS
Date: Mon, 31 Oct 2022 10:18:48 +0100	[thread overview]
Message-ID: <20221031091848.530938-1-pierre.gondois@arm.com> (raw)

Align arm64 DTS to the DeviceTree specification v0.3 regarding
cache properties. The patch-set mainly adds 'cache-level' or
'cache' compatibility properties.
For one qcom DTS, level 1 cache nodes are removed as they should
be in the cpu nodes.

On another node, it seems that the 'cache-unified' is under-used.
cache-unified:
  If present, specifies the cache has a unified or-
  ganization. If not present, specifies that the
  cache has a Harvard architecture with separate
  caches for instructions and data.
Only a few l2 cache nodes have this property, and in the absence
of [|d|i]-cache-size properties (or other), the cache is assumed to be
split.

The l2 cache of the Rockchip RK3308 platform is thus assumed to be
split:
l2: l2-cache {
	compatible = "cache";
	cache-level = <2>;
};
when the platform datasheet advertises a unified cache.

No modification/check was made to correct that due to the lack of
cache information for most platforms.
