[PATCH v3 0/4] acpi: Store _PLD information and convert users

[Heikki Krogerus <heikki.krogerus@linux.intel.com>]

Hi,

The _PLD buffer is no longer stored as requested by Rafael, so the
drivers will need to continue to evaluate the _PLD if they need it.

The stored locations will therefore only contain the list of other
devices that share the location, but that is most important, and in
practice the main goal of the series in any case.


v2 cover letter:

I'm now using the helpers device_match_acpi_dev() and
device_match_fwnode() like Andy suggested. No other changes.


The original cover letter:

This removes the need for the drivers to always separately evaluate
the _PLD. With the USB Type-C connector and USB port mapping this
allows us to start using the component framework and remove the custom
APIs.

So far the only users of the _PLD information have been the USB
drivers, but it seems it will be used also at least in some camera
drivers later. These nevertheless touch mostly USB drivers.

Rafael, is it still OK if Greg takes these?

Prashant, can you test these?

thanks,
