This is a friendly reminder during the review process.

It seems my previous comments were not fully addressed. Maybe my
feedback got lost between the quotes, maybe you just forgot to apply it.
Please go back to the previous discussion and either implement all
requested changes or keep discussing them.

Thank you.

NAK, not true based on previous discussions. Device does not come with
resets and clocks.


Best regards,

The code says:

In Aspeed AST2600 SoC features 16 TACH controllers, with each
controller capable of supporting up to 1 input.

which is a bit different. I guess there are no examples anymore,
but I'd really like to see how this looks like in the devicetree file,
and how the driver is supposed to distinguish/select the 16 inputs.
