2023-09-13acpi/soundwire.[ch]: Fix dpn entry array overrunMartin Roth
In soundwire.h, SOUNDWIRE_DPN MIN & MAX are set to 1 and 14. When creating the dpn array, the length was set to MAX - MIN or 13, numbered 0 to 12. When accessing the array, the code was bailing out if a value greater than MAX was trying to be accessed, so the array was able to be overrun by two structure lengths. Fix this problem by: 1) Not subtracting the MIN value when creating the array, which does waste a little space. If anyone wants to refactor the code to fix that, please feel free. 2) Breaking out of the loop when the port is equal to the MAX port number instead of just when it's greater than the max port number.

2020-05-21acpi/soundwire: Add functions to generate SoundWire propertiesDuncan Laurie
This change uses the previously added SoundWire definitions to provide functions that generate ACPI Device Properties for SoundWire controllers and codecs. A SoundWire controller driver should populate `struct soundwire_controller` and pass it to soundwire_gen_controller(). This will add all of the defined master links provided by the controller. A SoundWire codec driver should populate the necessary members in struct soundwire_codec and pass it to soundwire_gen_codec(). Several properties are optional and depend on whether the codec itself supports certain features and behaviors. The goal of this interface is to handle all of the properties defined in the SoundWire Discovery and Configuration Specification Version 1.0 so that controller and codec drivers do not need to all have code for writing standard properties. Both of these functions also provide a callback method for adding custom properties that are not defined by the SoundWire DisCo Specification. These properties may be required by OS drivers but are outside of the scope of the SoundWire specification itself. This code is tested with controller, codec, and mainboard implementations in subsequent commits.
