+Subject: USB: serial: option: add LARA-R6 01B PIDs
+
+From: Davide Tronchin <davide.tronchin.94@gmail.com>
+
+commit ffa5f7a3bf28c1306eef85d4056539c2d4b8eb09 upstream.
+
+The new LARA-R6 product variant identified by the "01B" string can be
+configured (by AT interface) in three different USB modes:
+
+* Default mode (Vendor ID: 0x1546 Product ID: 0x1311) with 4 serial
+interfaces
+
+* RmNet mode (Vendor ID: 0x1546 Product ID: 0x1312) with 4 serial
+interfaces and 1 RmNet virtual network interface
+
+* CDC-ECM mode (Vendor ID: 0x1546 Product ID: 0x1313) with 4 serial
+interface and 1 CDC-ECM virtual network interface
+The first 4 interfaces of all the 3 USB configurations (default, RmNet,
+CDC-ECM) are the same.
+
+In default mode LARA-R6 01B exposes the following interfaces:
+If 0: Diagnostic
+If 1: AT parser
+If 2: AT parser
+If 3: AT parser/alternative functions
+
+In RmNet mode LARA-R6 01B exposes the following interfaces:
+If 0: Diagnostic
+If 1: AT parser
+If 2: AT parser
+If 3: AT parser/alternative functions
+If 4: RMNET interface
+
+In CDC-ECM mode LARA-R6 01B exposes the following interfaces:
+If 0: Diagnostic
+If 1: AT parser
+If 2: AT parser
+If 3: AT parser/alternative functions
+If 4: CDC-ECM interface
