@roma-jam LGTM. What is the reason for targeting refactor/usb_host_parent_child_deps instead of master?

Just minor corrections

@tore-espressif,

the goal is to remove the parent_dev_hdl from the External Port driver, so the changes mainly affect external hubs and do not provide any potential risk for the devices, connected to the root port directly.

As we do not have the external hubs verification in CI, I did it manually (launch the pytest) and only for the last (part4/4) MR, which delivers the complete refactoring.

So, as reviewing the large amount of changes can provide difficulties and hide the main idea of the changes, I decided to split them to several logically independent PRs, targeting to a separate branch, to merge this branch later to master (with full refactoring in all layers).

UPD: but actually, I reviewed the changes in this exactly PR, keeping in mind your note and I see, that this one can be merged directly to master.
I will check the pytest locally with external hubs, and if there will be no problems, I could change the target branch to master for this one.

@roma-jam up to you. I agree that this 1st PR is simple enough and can be merged to master after 1.0.1 release

[roma-jam]

@tore-espressif I checked the usb_host test locally and we can change the target branch to master for with one.

can be merged to master after 1.0.1 release

I have created the next milestone after 1.0.1 release for this case.
