Calao use on there dev kits a FT2232 where the port 0 is used for the JTAG and port 1 for the UART They use the same VID and PID as FTDI Chip but they program the manufacturer name in the eeprom So use this information to detect it Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD Cc: Gregory Hermant Cc: Alan Cox Signed-off-by: Greg Kroah-Hartman Signed-off-by: Paul Gortmaker --- diff --git a/drivers/usb/serial/ftdi_sio.c b/drivers/usb/serial/ftdi_sio.c index c7e4fb83b44d..e8bc9086aff3 100644 --- a/drivers/usb/serial/ftdi_sio.c +++ b/drivers/usb/serial/ftdi_sio.c @@ -105,6 +105,7 @@ static int ftdi_jtag_probe(struct usb_serial *serial); static int ftdi_mtxorb_hack_setup(struct usb_serial *serial); static int ftdi_NDI_device_setup(struct usb_serial *serial); static int ftdi_stmclite_probe(struct usb_serial *serial); +static int ftdi_8u2232c_probe(struct usb_serial *serial); static void ftdi_USB_UIRT_setup(struct ftdi_private *priv); static void ftdi_HE_TIRA1_setup(struct ftdi_private *priv); @@ -132,6 +133,10 @@ static struct ftdi_sio_quirk ftdi_stmclite_quirk = { .probe = ftdi_stmclite_probe, }; +static struct ftdi_sio_quirk ftdi_8u2232c_quirk = { + .probe = ftdi_8u2232c_probe, +}; + /* * The 8U232AM has the same API as the sio except for: * - it can support MUCH higher baudrates; up to: @@ -181,7 +186,8 @@ static struct usb_device_id id_table_combined [] = { { USB_DEVICE(FTDI_VID, FTDI_8U232AM_PID) }, { USB_DEVICE(FTDI_VID, FTDI_8U232AM_ALT_PID) }, { USB_DEVICE(FTDI_VID, FTDI_232RL_PID) }, - { USB_DEVICE(FTDI_VID, FTDI_8U2232C_PID) }, + { USB_DEVICE(FTDI_VID, FTDI_8U2232C_PID) , + .driver_info = (kernel_ulong_t)&ftdi_8u2232c_quirk }, { USB_DEVICE(FTDI_VID, FTDI_4232H_PID) }, { USB_DEVICE(FTDI_VID, FTDI_MICRO_CHAMELEON_PID) }, { USB_DEVICE(FTDI_VID, FTDI_RELAIS_PID) }, @@ -1749,6 +1755,18 @@ static int ftdi_jtag_probe(struct usb_serial *serial) return 0; } +static int ftdi_8u2232c_probe(struct usb_serial *serial) +{ + struct usb_device *udev = serial->dev; + + dbg("%s", __func__); + + if (strcmp(udev->manufacturer, "CALAO Systems") == 0) + return ftdi_jtag_probe(serial); + + return 0; +} + /* * First and second port on STMCLiteadaptors is reserved for JTAG interface * and the forth port for pio
