Subject: [PATCH v2 00/23] Update cache properties for arm64 DTS
Date: Mon,  7 Nov 2022 16:56:53 +0100	[thread overview]
Message-ID: <20221107155825.1644604-1-pierre.gondois@arm.com> (raw)

v2:
- Update/Add patches for missed cache properties requiring to be
  updated for the following platforns: bcm, amazon, arm, exynos,
  freescale, marvell, mediatek, nvidia, socinext, tesla, ti.
  Missed cache properties were detected using Rob Herring's branch:
  https://github.com/robherring/dt-schema/tree/cache-rework
- v1 of exynos, tesla were merged.
- Updated wrong reference in commit message.
- Added received Rb/Acked-by.

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.
