[v3,00/18] usb: typec: API improvements

Message

Hi,

I modified ucsi_acpi.c so that the behavior matches exactly the
behaviour of the Connector Change Event handling before these patches.

The cover letter from v2:

There is now a check in ucsi_exec_command() that makes sure we do not
call ucsi_read_error() with UCSI_GET_ERROR_STATUS command. That should
prevent endless recursion from happening.

The original cover letter:

The first patches in this series (patches 1-8) introduce a small
change to the USB Type-C Connector Class API. Guenter was kind enough
to go over those already.

Patches 10-15 improve the ucsi driver API by introducing more
traditional read and write routines, and the rest is more generic
optimisations and improvements to the ucsi drivers.

Let me know if there is anything you want to be changed.

thanks,
