The validity of the ftdi CBUS GPIO is pretty hidden so far,
and finding out *why* some GPIOs don't work is sometimes
hard to identify. So let's help the user by displaying the
map of the CBUS pins that are valid for a GPIO.

Add a helper function to be used to configure flow control.
The flow-control code was the last caller that relied on the
memset-on-failure behaviour of cp210x_read_reg_block(), which we can now
drop in favour of bailing out on errors when retrieving the flow-control
settings.
This should also simplify adding support for software flow control.

Drop some unnecessary flow-control debugging.
Signed-off-by: Johan Hovold <[email protected]>
|

Unlike other drivers cp210x have been retrieving the current terminal
settings from the device on open and reflecting those in termios.
Due to how set_termios() used to be implemented, this saved a few
control requests on open but has instead caused problems like broken
flow control and has required adding workarounds for swapped
line-control in cp2108 and line-speed initialisation on cp2104.
This unusual implementation also complicates adding new features for no
good reason.
Rip out the corresponding code and the above mentioned workarounds and
instead initialise the terminal settings unconditionally on open.

Update the line-control settings in one request unconditionally instead
of setting the word-length, parity and stop-bit settings separately.
This avoids multiple requests when several settings are changed even if
this scheme could potentially also be used to detect unsupported device
settings. Since all device types but CP2101 appears to support all
settings, let's handle that one specifically and also report back the
unsupported settings properly through termios by clearing the
corresponding bits.
Also drop the related unnecessary debug printks.

Return early from set_termios() in case no relevant terminal settings
have changed.
This avoids testing each parameter in turn and specifically allows the

The parallel port restore operation currently defers writes
to a tasklet, if it sees a locked disconnect mutex. The
driver goes to a lot of trouble to ensure writes happen
in a non-blocking context, but things can be greatly
simplified if it's done in regular process context and
this is not a system performance critical path. As such,
instead of doing the state restore writes in softirq context,
use a workqueue and just do regular synchronous writes.
In addition to the cleanup, this also imposes less on the
overall system as tasklets have been deprecated because
of it's softirq implications, potentially blocking a higher
priority task from running.

Use the port write fifo and generic chars_and_buffer and write_room
implementations when writing. This not only allows for more efficient
transfers, but more importantly fixes the remaining issues related to
the conservative write_room() implementation which could prevent the
line discipline from making forward progress (e.g. waiting for n > 1
bytes of space to become available).
Note that this also allows using the driver for the system console
without dropping data when the write URB is busy (including when adding
carriage return on line feed).

Fix stalled writes by checking the available buffer space after
requesting an unthrottle notification in case the device buffer is
already empty so that no notification is ever sent (e.g. when doing

This also means we can drop the room query from write() which was
conditioned on in_interrupt() and prevented writing using this driver

The driver did not update its view of the available device buffer space
until write() was called in task context. This meant that write_room()
would return 0 even after the device had sent a write-unthrottle
notification, something which could lead to blocked writers not being
woken up (e.g. when using OPOST).
Note that we must also request an unthrottle notification is case a
write() request fills the device buffer exactly.

The usage of in_interrupt() in drivers is phased out and Linus clearly
requested that code which changes behaviour depending on context should
either be separated or the context be conveyed in an argument passed by the
caller, which usually knows the context.
The debug printk() in digi_write() prints in_interrupt() as context
information. This information is imprecise as it does not distinguish
between hard-IRQ or disabled bottom half and it does not consider
disabled interrupts or preemption. It is not really helpful.
Remove the in_interrupt() printout.

Commit 21653a4181ff ("i2c: core: Call i2c_acpi_install_space_handler()

acpi_install_address_space_handler() call to the point before where
the ACPI declared i2c-children of the adapter where instantiated by
i2c_acpi_register_devices().
But i2c_acpi_install_space_handler() had a call to
acpi_walk_dep_device_list() hidden (that is I missed it) at the end
of it, so as an unwanted side-effect now acpi_walk_dep_device_list()
was also being called before i2c_acpi_register_devices().
Move the acpi_walk_dep_device_list() call to the end of
i2c_acpi_register_devices(), so that it is once again called *after*
the i2c_client-s hanging of the adapter have been created.
This fixes the Microsoft Surface Go 2 hanging at boot.
