-// 2). this is a 'current' file. If you make a backwards compatible change to

-//
-// You must not make a backward incompatible change to any AIDL file built
-// with the aidl_interface module type with versions property set. The module
-// type is used to build AIDL files in a way that they can be used across
-// independently updatable components of the system. If a device is shipped
-// with such a backward incompatible change, it has a high risk of breaking

-// This file is a snapshot of an AIDL file. Do not edit it manually. There are
-// two cases:
-// 1). this is a frozen version file - do not edit this in any case.
-// 2). this is a 'current' file. If you make a backwards compatible change to
-//     the interface (from the latest frozen version), the build system will
-//     prompt you to update this file with `m <name>-update-api`.
-//
-// You must not make a backward incompatible change to any AIDL file built
-// with the aidl_interface module type with versions property set. The module
-// type is used to build AIDL files in a way that they can be used across
-// independently updatable components of the system. If a device is shipped
-// with such a backward incompatible change, it has a high risk of breaking
-// later when a module using the interface is updated, e.g., Mainline modules.

+     * multiple modes would be required is if a chip has different firmwares with
+     * different capabilities.
+     *
+     * When in a mode, it must be possible to perform any combination of creating

+     * ChipConcurrencyCombinations is satisfied. This means that if a chip has two

+     * that exactly one STA type or one AP_BRIDGED type can be created, but it

+     * [{STA} <=1, {AP_BRIDGED} <= 1].
+     *
+     * When switching between two available combinations it is expected that

+     * the target combination is also satisfied. At that point new interfaces

+     * combination limits will no longer satisfied). The addition of these new
+     * interfaces must not impact the existence of interfaces that satisfy both
+     * combinations.
+     *
+     * For example, a chip with available combinations:
+     *     [{STA} <= 2, {NAN} <=1] and [{STA} <=1, {NAN} <= 1, {AP_BRIDGED} <= 1}]
+     * If the chip currently has 3 interfaces STA, STA and NAN and wants to add an
+     * AP_BRIDGED interface in place of one of the STAs then first one of the STA
+     * interfaces must be removed and then the AP interface can be created after
+     * the STA had been torn down. During this process the remaining STA and NAN
+     * interfaces must not be removed/recreated.
+     *
+     * If a chip does not support this kind of reconfiguration in this mode then
+     * the combinations must be separated into two separate modes. Before

+     * enacted and when it completes the new interfaces must be brought up.
