Please fix your machine time, so this does not appear in +8 hours in the
future. It unnecessarily goes to the top of my inbox, so I will ignore
the patchset.

[PATCH v6 4/9] dt-bindings: usb: add NXP ChipIdea USB2 Controller schema

[Xu Yang]

As more and more NXP i.MX chips come out, it becomes harder to maintain
ci-hdrc-usb2.yaml if more stuffs like property restrictions are added to
this file. This will separate i.MX parts out of ci-hdrc-usb2.yaml and add
a new schema for NXP ChipIdea USB2 Controller.

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

Now you just duplicated all the compatibles, and now any new compatibles 
have to be added in 2 places. For this to work, you have to split 
ci-hdrc-usb2.yaml into 2 files. One with all the common properties and 
one with compatibles (minus imx). This is also needed if imx has any 
extra properties the other don't.

Didn't I say this already?

Yes, I know.

But according to your words, I need to split ci-hdrc-usb2.yaml into 1 common
file and more than 1 vendor specific files (imx, nvidia, qcom, nuvoton and
others). In this patchset, I only focus on imx part and KK said he or someone
will take over other parts, therefore I just duplicated all the imx compatibles.
If I only create imx specific yaml file and remove all compatilbles from common
file, nvidia, qcom, nuvoton and others compatible info will be lost, is this
feasible? Or should I create mutiple vendor specific files at the same time?

Thanks,

This series is just wasting our time because it can't be applied without that.

You don't have to split each vendor to a separate vendor schema file.
Just move everything common to ci-hdrc-usb2-common.yaml and add a
reference to it. Then imx can reference the common file.

Someone will take over their bits, but it does not mean you can
duplicate IMX. Why you cannot use the approach I asked - move IMX out of
that schema?

https://lore.kernel.org/all/a0134089-a283-488b-8d7f-3f59dd938b60@linaro.org/

Look:
"... and move IMX to own file."

Move is not "copy". Please run: `man mv`

> If I only create imx specific yaml file and remove all compatilbles from common

Why would you remove ALL of others? What is the point of this.

You can take a look how it is done in my recent Qualcomm PCI dt-bindings
series.

I originally thought ci-hdrc-usb2.yaml should be removed and only
ci-hdrc-usb2-comm.yaml is kept. So I'm not sure where other compatibles
should go. I looked though your Qualcomm PCI dt-bindings series and now
I know how to do.
