Series Update cache properties for arm64 DTS |

Commit Message

Pierre Gondois Nov. 7, 2022, 3:57 p.m. UTC 
  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 'cache-unified' property should be present if one of the
properties for unified cache is present ('cache-size', ...).

Update the Device Trees accordingly.

"compatible" is present?

Present, too?

This hunk now applies to arch/arm64/boot/dts/renesas/r9a07g043u.dtsi.

Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be>
i.e. will queue in renesas-devel for v6.2, with the patch description
and the file names updated to match the real world.

Gr{oetje,eeting}s,

                        Geert
