+description:
+ The EcoNet High Precision Timer (HPT) is a timer peripheral found in various
+ EcoNet SoCs, including the EN751221 and EN751627 families. It provides per-VPE
+ count/compare registers and a per-CPU control register, with a single interrupt
+ line using a percpu-devid interrupt mechanism.

Nothing explains dropping the tag. <form letter> This is a friendly reminder during the review process. It looks like you received a tag and forgot to add it. If you do not know the process, here is a short explanation: Please add Acked-by/Reviewed-by/Tested-by tags when posting new versions of patchset, under or above your Signed-off-by tag, unless patch changed significantly (e.g. new properties added to the DT bindings). Tag is "received", when provided in a message replied to you on the mailing list. Tools like b4 can help here. However, there's no need to repost patches *only* to add the tags. The upstream maintainer will do that for tags received on the version they apply. Please read: https://elixir.bootlin.com/linux/v6.12-rc3/source/Documentation/process/submitting-patches.rst#L577 If a tag was not added on purpose, please state why and what changed. </form letter> Best regards, Krzysztof
