One new device ID for CP2101 driver.
Signed-off-by: Alex Stephens alex@miranova.com
|
|
The ipaq driver currently enforces one port on all devices. This
is correct for 2 and 3 endpoint devices, but with 4 endpoint devices
meaningful communication occurs on the second pair.
This patch allows 2 ports for 4 endpoint devices.

Lots of users are getting confused about the cp2101 driver. It really
does support more than just the cp2101 device, so rename it to cp210x to
try to prevent confusion.

This patch adds support for the extended range of baud rates supported
by CP2102 and CP2103 devices described in SiLabs AN205. An additional
function cp2101_quantise_baudrate rounds the baud rate as per AN205
Table 1. A modification to the baud rate calculation removes a rounding
error, allowing the full range of baud rates to be used.

actual_length should also be a u32 and not a signed value. This patch
changes this field to be 'u32' to prevent any potential negative
conversion and comparison errors.
This triggered a few compiler warning messages when these fields were
being used with the min macro, so they have also been fixed up in this
patch.

This patch fixes the following bug:
.plug ch341 usb serial port into a hub port;
.ch341 driver bound to the device and /dev/ttyUSB0 comes
.open /dev/ttyUSB0 by minicom and we can use the serial successfully
.suspend the ch341 usb serial device(such as: echo suspend > power/level)
.resume the ch341 usb serial device (such as: echo on > power/level)
.new port /dev/ttyUSB1 comes ,and the original /dev/ttyUSB0 still exists,
but is no longer usable by minicom
The patch adds suspend and resume callback to ch341 usb driver to prevent it
from unbinding during suspend. The /dev/ttyUSB0 is not released until being
closed, so /dev/ttyUSB1 comes after resume, and the original /dev/ttyUSB0 is
no longer usable by minicom. It is really a mess for a minicom user.
This patch also adds the reset_resume callback to make it usable after resuming
from STR or hibernation, for generally STR or hibernation will make the vbus
of root-hub lost.
Finally enable the driver's supports_autosuspend, for the device is in working
order with it.

With "nousb" cmdline booting, built-in serial drivers (ie. airecable)
will trigger kernel oops.
Indeed, if nousb, usb_serial_init will failed, and the usb serial bus type
will not be registerd, then usb_serial_register call driver_register
which try to register the driver to a not registered bus.
Here add usb_disabled() check in usb_serial_register to fix it.

Driver originally written by Qualcomm, but rewritten by me due to the
totally different coding style. Cleaned up the probe logic to make a
bit more sense, this is one wierd device. They could have prevented all
of this by just writing sane firmware for the modem.

A USB-serial converter device is plugged into a system, and a process
opens it's device node. If the device is physically removed whilst the
process still has its device node open, then other processes can
sucessfully open the now non-existent device's node. I would expect
that open() on a device that has been physically removed should return
ENODEV.
This is manifesting itself with getty on my system. I do the following:
1. set up inittab to spawn getty on ttyUSB0, eg:
T1:23:respawn:/sbin/getty -L ttyUSB0 115200 vt100
2. Plug in USB-serial converter cable
3. Wait for a login prompt on a terminal program attached to the serial
cable
4. Login
5. Pull the USB-serial converter cable from the box
6. getty doesn't realise that ttyUSB0 no longer exists as /dev/ttyUSB0
can still be opened.
7. Re-insert the USB-serial converter cable
8. You should no longer get a login prompt over the serial cable, as
the the USB-serial cable now shows up as /dev/ttyUSB1, and getty is
trying to talk to /dev/ttyUSB0.
The attached patch will cause open("/dev/ttyUSB0", O_RDONLY) to return
ENODEV after the USB-serial converter has been pulled. The patch was
created against 2.6.28.1. I can supply it against something else if
needs be. It is fairly simple, so should be OK.
I am using a pl2303 device, although I don't think that makes any
difference.

This removes the fallback to the generic method. It is cleaner to
explicitely request it. Introducing this was my mistake. This will
be solved by an explicit test and the driver being allowed to request
what it needs to be done upon resumption.

This removes an unnecessary check for autoresume from the generic
resume method. The check has been obsoleted by the now delayed
increase of the usage counter which makes the error this check prevented
impossible. This change allows drivers which only use the bulk read URB
the use of the generic method even if they support autosuspend.

Fixup of Werner Cornelius patch to the ch341 USB-serial driver, which adds:
- support all baudrates, not just a hard-coded set
- support for controlling DTR, RTS and CTS
Features still missing:
- character length other than 8 bits
- parity settings
- break control
I adapted his patch for the new usb_serial API introduced in 2.6.25-git8 by
Alan Cox on 22 July 2008. Non-compliance to the new API was a reason for
refusing a similar patch from Tollef Fog Heen.

This set of patches introduces calls to the following set of functions:
usb_endpoint_dir_in(epd)
usb_endpoint_dir_out(epd)
usb_endpoint_is_bulk_in(epd)
usb_endpoint_is_bulk_out(epd)
usb_endpoint_is_int_in(epd)
usb_endpoint_is_int_out(epd)
usb_endpoint_num(epd)
usb_endpoint_type(epd)
usb_endpoint_xfer_bulk(epd)
usb_endpoint_xfer_control(epd)
usb_endpoint_xfer_int(epd)
usb_endpoint_xfer_isoc(epd)
In some cases, introducing one of these functions is not possible, and it
just replaces an explicit integer value by one of the following constants:
USB_ENDPOINT_XFER_BULK
USB_ENDPOINT_XFER_CONTROL
USB_ENDPOINT_XFER_INT
USB_ENDPOINT_XFER_ISOC
An extract of the semantic patch that makes these changes is as follows:

the pieces are in place (ie, cac477e8f1038c41b6f29d3161ce351462ef3df7).
