[PATCH v5 8/8] usb: chipidea: ci_hdrc_imx: align usb wakeup clock name with dt-bindings

The dt-bindings is going to use "usb_wakeup" as wakup clock name. This will
align the change with dt-bindings.

This would be just: enum: [ipg, ahb, per], but in both cases I question
why the order should be flexible? Nothing in commit msg explains it.

Plus I will repeat myself from your v4. I don't think this is helping,
because the file will soon grow to umnanageable chunk. I prefer to fix
it at beginning, before we reach snps-schema level of complexities.

Please define common schema, reference in this file and move IMX to own
file.

In any case, please provide short comment in the code why you have such
duplicated if:then:

Best regards,
Krzysztof

No, clocks must be fixed and specific. No contains allowed for new variants.

The driver will get the clock by clock-name, then the order should not
matter. However, these three clock-names should be present at the same
time. I should use enum then.

I'm not that familiar with dt-bindings architecture. If I define a common
schema, then should I create imx, qcom, nvidia and other dt-binding files
too?

Because fsl,imx93-usb is compatible with fsl,imx7d-usb and only imx93 needs
wakeup clock, so I remove fsl,imx7d-usb from previous if-then restriction.
Otherwise, when do dt-validate for imx93, it will require 1 clocks and 1 clock-names
property. Then imx7d and imx8* socs will lost restrictions on clocks and clock-names.

Then I still need add restrictions for compatible = 'fsl,imx7d-usb ', 'fsl,imx27-usb '
and other compatibles like 'fsl,imx8mm-usb', 'fsl,imx7d-usb, 'fsl,imx27-usb''. So the
below changes are for this purpose.

Well, I will change this then.

No, the rest you can leave here. Someone, maybe me, will move them some
time. The point is to move at least IMX to its own file.

Forgot to answer to this.

Which driver? U-boot? OpenBSD? The one in my custom Linux kernel fork
(open-source and published on github)? Did you check all of them?

The order should be strict (or "fixed" as in non-flexible), unless there
is some reason against. If one driver does not care about order, is not
the reason.

This comment applies to all bindings so to all your future
contributions. I really keep repeating it...

That will only work as long as i.MX doesn't define any extra properties 
which it already has. We have to have at a minium common, imx, and 
everything else schema docs.
