commit ad1244e1ce18f8c1a5ebad8074bfcf10eacb0311 upstream.

T99W709 is designed based on MTK T300(5G redcap) chip. There are
7 serial ports to be enumerated: AP_LOG, GNSS, AP_META, AT,
MD_META, NPT, DBG. RSVD(5) for ADB port.

commit c980666b6958d9a841597331b38115a29a32250e upstream.

NDI (Northern Digital Inc.) is introducing a new product called the
EMGUIDE GEMINI that will use an FTDI chip for USB serial communications.
Add the NDI EMGUIDE GEMINI product ID that uses the NDI Vendor ID
rather than the FTDI Vendor ID, unlike older products.

Add serial support for OWON HDS200 series oscilloscopes and likely
many other pieces of OWON test equipment.

OWON HDS200 series devices host two USB endpoints, designed to
facilitate bidirectional SCPI. SCPI is a predominately ASCII text
protocol for test/measurement equipment. Having a serial/tty interface

OWON appears to be using the same USB Vendor and Product ID for many
of their oscilloscopes. Looking at the discussion about the USB
vendor/product ID, in the link bellow, suggests that this VID/PID is
shared with VDS, SDS, PDS, and now the HDS series oscilloscopes.
Available documentation for these devices seems to indicate that all
use a similar SCPI protocol, some with RS232 options. It is likely that
this same simple serial setup would work correctly for them all.

Add serial support for OWON HDS200 series oscilloscopes and likely
many other pieces of OWON test equipment.

OWON HDS200 series devices host two USB endpoints, designed to
facilitate bidirectional SCPI. SCPI is a predominately ASCII text
protocol for test/measurement equipment. Having a serial/tty interface
for these devices lowers the barrier to entry for anyone trying to
write programs to communicate with them.

Abacus Electrics makes optical probes for interacting with smart meters
over an optical interface.

At least one version uses an FT232B chip (as detected by ftdi_sio) with
a custom USB PID, which needs to be added to the list to make the device
work in a plug-and-play fashion.

<title>USB: serial: ftdi_sio: add support for Altera USB Blaster 3</title>

<id>18e0885bd2ca738407036434418a26a58394a60e</id>
<content type='text'>
The Altera USB Blaster 3, available as both a cable and an on-board
solution, is primarily used for programming and debugging FPGAs.

It interfaces with host software such as Quartus Programmer,
System Console, SignalTap, and Nios Debugger. The device utilizes
either an FT2232 or FT4232 chip.

Enabling the support for various configurations of the on-board
USB Blaster 3 by including the appropriate VID/PID pairs,
allowing it to function as a serial device via ftdi_sio.

Note that this check-in does not include support for the
cable solution, as it does not support UART functionality.
The supported configurations are determined by the
hardware design and include:

1) PID 0x6022, FT2232, 1 JTAG port (Port A) + Port B as UART
2) PID 0x6025, FT4232, 1 JTAG port (Port A) + Port C as UART
3) PID 0x6026, FT4232, 1 JTAG port (Port A) + Port C, D as UART
4) PID 0x6029, FT4232, 1 JTAG port (Port B) + Port C as UART
5) PID 0x602a, FT4232, 1 JTAG port (Port B) + Port C, D as UART
6) PID 0x602c, FT4232, 1 JTAG port (Port A) + Port B as UART
7) PID 0x602d, FT4232, 1 JTAG port (Port A) + Port B, C as UART
8) PID 0x602e, FT4232, 1 JTAG port (Port A) + Port B, C, D as UART

These configurations allow for flexibility in how the USB Blaster 3 is
used, depending on the specific needs of the hardware design.

Enabling the support for various configurations of the on-board
USB Blaster 3 by including the appropriate VID/PID pairs,
allowing it to function as a serial device via ftdi_sio.

Note that this check-in does not include support for the
cable solution, as it does not support UART functionality.
The supported configurations are determined by the
hardware design and include:

1) PID 0x6022, FT2232, 1 JTAG port (Port A) + Port B as UART
2) PID 0x6025, FT4232, 1 JTAG port (Port A) + Port C as UART
3) PID 0x6026, FT4232, 1 JTAG port (Port A) + Port C, D as UART
4) PID 0x6029, FT4232, 1 JTAG port (Port B) + Port C as UART
5) PID 0x602a, FT4232, 1 JTAG port (Port B) + Port C, D as UART
6) PID 0x602c, FT4232, 1 JTAG port (Port A) + Port B as UART
7) PID 0x602d, FT4232, 1 JTAG port (Port A) + Port B, C as UART
8) PID 0x602e, FT4232, 1 JTAG port (Port A) + Port B, C, D as UART

These configurations allow for flexibility in how the USB Blaster 3 is
used, depending on the specific needs of the hardware design.
