[PATCH 0/2] Enable PPS reporting for USB serial devices (v3)

Hi. This series enable the PPS reporting for USB serial devices. This third submission improve commit messages, and fix some coding guidelines. The last patch of the v2 will be integrated in an more global reworking of the pl2303 driver. Paul Chavent (2): USB : serial : call handle_dcd_change

[PATCH 1/2] USB : serial : call handle_dcd_change in ftdi driver.

When the device receive a DCD status change, forward the signal to the USB serial system. This way, we can detect, for instance, PPS pulses. Signed-off-by: Paul Chavent --- drivers/usb/serial/ftdi_sio.c | 10 +- 1 file changed, 9 insertions(+), 1 deletion(-) diff --git a/drivers/usb

[PATCH 2/2] USB : serial : invoke dcd_change ldisc's handler.

The DCD pin of the serial port can receive a PPS signal. By calling the port line discipline dcd handle, this patch allow to monitor PPS through USB serial devices. However the performance aren't as good as the uart drivers, so document this point too. Signed-off-by: Paul Ch

[PATCH 2/5] USB : serial : get protected tty in handle_dcd_change.

This patch depends on 72df17e... (PATCH 1). It restores the retreiving of a protected instance of tty. As opposed to the serialcore.c dcd_change implementation, the callers of dcd_change used to get protected tty instance. Signed-off-by: Paul Chavent --- drivers/usb/serial/generic.c | 4

Re: [PATCH 0/5] Enable PPS reporting for USB serial devices

he usb, and see if it is constant. Perhaps we could introduce parameters to add offset to the pps signal used by the kernel consumer (the same way we can add the offset with PPS_FETCH ioctl) later. Regards. Paul. On 09/10/2013 09:31 AM, Rodolfo Giometti wrote: On Mon, Sep 09, 2013 at 06:01

Hi. This patch was just a suggestion. Don't bother with rebasing. I will wait your changes and remove this patch from the next submission. Cheers. Paul. On 09/13/2013 06:23 PM, Johan Hovold wrote: On Fri, Sep 13, 2013 at 05:35:13PM +0200, Paul Chavent wrote: Seems to be done this w

Hello and happy new year 2008. In drivers/usb/serial/usb-serial.c there is a function (fixup_generic / set_to_generic_if_null) that hooks null fops to the generic driver ones. The drivers/usb/serial/generic.c implements throttle, unthrottle and resume, but those aren't used by default in fixu

Hi. I haven't had any feedback for weeks. I join a patch with more details in the commit message if needed. Do you know someone responsible to apply PPS patches ? Regards. Paul. On 09/06/2013 08:55 AM, Rodolfo Giometti wrote: On Wed, Sep 04, 2013 at 10:20:38AM +0200, Paul Chavent

[PATCH] pps : add non blocking option to PPS_FETCH ioctl.
