USB-serial updates for 5.15-rc1
Here are the USB serial updates for 5.15-rc1, including:
- a couple of fixes for cp210x termios error handling
- retrieval of fw revisions for more cp210x types
- a switch to octal permissions for all module-parameter definitions
Included are also various clean ups.
All have been in linux-next with no reported issues.

Replace symbolic permission macros with octal permission numbers
because octal permission numbers are easier to read and understand
instead of their symbolic macro names.
No functional change.

The TIOCSSERIAL implementation needs to compare the old flag and divisor
settings with the new to detect ASYNC_SPD changes, but there's no need
to copy all driver state to the stack for that.
While at it, unbreak the function parameter list.

Changing the deprecated custom_divisor field is an unprivileged
operation so after verifying that flag field does not contain any
privileged changes both updates can be carried out by any user.
Combine the two branches and drop the erroneous comment.
Note that private flags field is only used for ASYNC flags so there's no
need to try to retain any other bits when updating the flags.

The TIOCSSERIAL error handling is inconsistent at best, but drivers tend
to ignore requests to change parameters which cannot be changed rather
than return an error.
The FTDI driver ignores change requests for all immutable parameters but
baud_base so return success also in this case for consistency.

TIOCSSERIAL is a horrid, underspecified, legacy interface which for most
serial devices is only useful for setting the close_delay and
closing_wait parameters.
The closing_wait parameter determines how long to wait for the transfer
buffers to drain during close and the default timeout of 30 seconds may
not be sufficient at low line speeds. In other cases, when for example
flow is stopped, the default timeout may instead be too long.
Add generic support for TIOCSSERIAL and TIOCGSERIAL with handling of the
three common parameters close_delay, closing_wait and line for the
benefit of all USB serial drivers while still allowing drivers to
implement further functionality through the existing callbacks.
This currently includes a few drivers that report their base baud clock
rate even if that is really only of interest when setting custom
divisors through the deprecated ASYNC_SPD_CUST interface; an interface
which only the FTDI driver actually implements.
Some drivers have also been reporting back a fake UART type, something
which should no longer be needed and will be dropped by a follow-on
patch.

these, but let's report back the default values actually used (0.5 and

There exist many FT2232-based JTAG+UART adapter designs in which
FT2232 Channel A is used for JTAG and Channel B is used for UART.
The best way to handle them in Linux is to have the ftdi_sio driver
create a ttyUSB device only for Channel B and not for Channel A:
a ttyUSB device for Channel A would be bogus and will disappear as
soon as the user runs OpenOCD or other applications that access
Channel A for JTAG from userspace, causing undesirable noise for
users. The ftdi_sio driver already has a dedicated quirk for such
JTAG+UART FT2232 adapters, and it requires assigning custom USB IDs
to such adapters and adding these IDs to the driver with the
ftdi_jtag_quirk applied.
Boutique hardware manufacturer Falconia Partners LLC has created a
couple of JTAG+UART adapter designs (one buffered, one unbuffered)
as part of FreeCalypso project, and this hardware is specifically made
to be used with Linux hosts, with the intent that Channel A will be
accessed only from userspace via appropriate applications, and that
Channel B will be supported by the ftdi_sio kernel driver, presenting
a standard ttyUSB device to userspace. Toward this end the hardware
manufacturer will be programming FT2232 EEPROMs with custom USB IDs,
specifically with the intent that these IDs will be recognized by
the ftdi_sio driver with the ftdi_jtag_quirk applied.

Only the last NUL in a packet should be flagged as a break character,
for example, to avoid dropping unrelated characters when IGNBRK is set.
Also make sysrq work by consuming the break character instead of having
it immediately cancel the sysrq request, and by not processing it
prematurely to avoid triggering a sysrq based on an unrelated character
received in the same packet (which was received *before* the break).
Note that the break flag can be left set also for a packet received
immediately following a break and that and an ending NUL in such a
packet will continue to be reported as a break as there's no good way to
tell it apart from an actual break.
Tested on FT232R and FT232H.

There is a bug in the current GPIO code for ftdi_sio: it failed to take USB
autosuspend into account. If the device is in autosuspend, calls to
usb_control_msg() fail with -EHOSTUNREACH. Because the standard value for
autosuspend timeout is usually 2-5 seconds, this made it almost impossible
to use the GPIOs on machines that have USB autosuspend enabled. This patch
fixes the issue by acquiring a PM lock on the device for the duration of
the USB transfers. Tested on an FT231X device.

Improve baud-rate generation by using rounding-to-closest instead of
truncation in divisor calculation.
Results have been verified by logic analyzer on an FT232RT (232BM) chip.
The following table shows the wanted baud rate, the baud rate obtained
with the old method (truncation), with the new method (rounding) and the
baud rate generated by the windows 10 driver. The numbers in parentheses
is the error.
+- Wanted --+------ Old -------+------ New -------+------ Win -------+
| 9600 | 9600 (0.00%) | 9604 (0.05%) | 9605 (0.05%) |
| 19200 | 19200 (0.00%) | 19199 (0.01%) | 19198 (0.01%) |
| 38400 | 38395 (0.01%) | 38431 (0.08%) | 38394 (0.02%) |
| 57600 | 57725 (0.22%) | 57540 (0.10%) | 57673 (0.13%) |
| 115200 | 115307 (0.09%) | 115330 (0.11%) | 115320 (0.10%) |
| 921600 | 919963 (0.18%) | 920386 (0.13%) | 920810 (0.09%) |
| 961200 | 996512 (3.67%) | 956480 (0.49%) | 956937 (0.44%) |
+-----------+------------------+------------------+------------------+
The error due to noise in the measurements is in the order of a few
tenths of a %. As can be seen, the baud rate is significantly improved
for some rates (e.g. 961200), and corresponds to the output given by the
windows driver.
The theoretical baud rate has been calculated for all baud rates from 1
to 3M, and as expected, the error is centered around 0, with a triangle
shape instead of a sawtooth, so the maximum error is decreased to half.

This patch allows using the CBUS pins of FT-X devices as GPIO in CBUS
bitbanging mode. There is no conflict between the GPIO and VCP
functionality in this mode. Tested on FT230X and FT231X.
As there is no way to request the current CBUS register configuration
from the device, all CBUS pins are set to a known state when the first
GPIO is requested. This allows using libftdi to set the GPIO pins
before loading this module for UART functionality, a behavior that
existing applications might be relying upon (though no specific case
is known to the authors of this patch).
