USB: serial: option: support dynamic Quectel USB compositions

2020-08-31T06:37:17+00:00

The USB composition, defining the set of exported functions, is dynamic
in newer Quectel modems.  Default functions can be disabled and
alternative functions can be enabled instead.  The alternatives
includes class functions using interface pairs, which should be
handled by the respective class drivers.

Active interfaces are numbered consecutively, so static
blacklisting based on interface numbers will fail when the
composition changes.  An example of such an error, where the
option driver has bound to the CDC ECM data interface,
preventing cdc_ether from handling this function:

Another device with the same id gets correct drivers, since the
interface of the network function happens to be blacklisted by option:

Change rules for EC21, EC25, BG96 and EG95 to match vendor specific
serial functions only, to prevent binding to class functions. Require
2 endpoints on ff/ff/ff functions, avoiding the 3 endpoint QMI/RMNET
network functions.

USB: serial: option: add support for SIM7070/SIM7080/SIM7090 modules

2020-08-31T06:33:41+00:00

These modules have 2 different USB layouts:

The default layout with PID 0x9205 (AT+CUSBSELNV=1) exposes 4 TTYs and
an ECM interface:

  T:  Bus=02 Lev=01 Prnt=01 Port=02 Cnt=01 Dev#=  6 Spd=480 MxCh= 0
  D:  Ver= 2.00 Cls=ef(misc ) Sub=02 Prot=01 MxPS=64 #Cfgs=  1
  P:  Vendor=1e0e ProdID=9205 Rev=00.00
  S:  Manufacturer=SimTech, Incorporated
  S:  Product=SimTech SIM7080
  S:  SerialNumber=1234567890ABCDEF
  C:  #Ifs= 6 Cfg#= 1 Atr=e0 MxPwr=500mA
  I:  If#=0x0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x1 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x2 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x3 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x4 Alt= 0 #EPs= 1 Cls=02(commc) Sub=06 Prot=00 Driver=cdc_ether
  I:  If#=0x5 Alt= 1 #EPs= 2 Cls=0a(data ) Sub=00 Prot=00 Driver=cdc_ether

The purpose of each TTY is as follows:
 * ttyUSB0: DIAG/QCDM port.
 * ttyUSB1: GNSS data.
 * ttyUSB2: AT-capable port (control).
 * ttyUSB3: AT-capable port (data).

In the secondary layout with PID=0x9206 (AT+CUSBSELNV=86) the module
exposes 6 TTY ports:

  T:  Bus=02 Lev=01 Prnt=01 Port=02 Cnt=01 Dev#=  8 Spd=480 MxCh= 0
  D:  Ver= 2.00 Cls=02(commc) Sub=00 Prot=00 MxPS=64 #Cfgs=  1
  P:  Vendor=1e0e ProdID=9206 Rev=00.00
  S:  Manufacturer=SimTech, Incorporated
  S:  Product=SimTech SIM7080
  S:  SerialNumber=1234567890ABCDEF
  C:  #Ifs= 6 Cfg#= 1 Atr=e0 MxPwr=500mA
  I:  If#=0x0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x1 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x2 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x3 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x4 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x5 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=option

The purpose of each TTY is as follows:
 * ttyUSB0: DIAG/QCDM port.
 * ttyUSB1: GNSS data.
 * ttyUSB2: AT-capable port (control).
 * ttyUSB3: QFLOG interface.
 * ttyUSB4: DAM interface.
 * ttyUSB5: AT-capable port (data).
