https://git.0xinfinity.dev/distro/kernel.git/atom?h=linux-3.4.y2014-04-14T13:44:17Zpps: Use pps_lookup_dev to reduce ldisc coupling2014-04-14T13:44:17ZGeorge Spelvin2013-02-10T09:41:56Zurn:sha1:0965dca06d3659d7cdab7a7e40694affc21be3c9
commit 03a7ffe4e542310838bac70ef85acc17536b6d7c upstream.
Now that N_TTY uses tty->disc_data for its private data,
'subclass' ldiscs cannot use ->disc_data for their own private data.
(This is a regression is v3.8-rc1)
Use pps_lookup_dev to associate the tty with the pps source instead.
This fixes a crashing regression in 3.8-rc1.

pps: timestamp is always passed to dcd_change()2011-01-13T16:03:20ZAlexander Gordeev2011-01-13T01:00:55Zurn:sha1:12f9b1f9c11700893a7b453705d95b260d78f268
Remove the code that gatheres timestamp in pps_tty_dcd_change() in case
passed ts parameter is NULL because it never happens in the current code.
Fix comments as well.

pps: convert printk/pr_* to dev_*2011-01-13T16:03:19ZAlexander Gordeev2011-01-13T01:00:52Zurn:sha1:7f7cce74105adf714bdc9357da3b6f06e019958c
Since we now have direct pointers to struct pps_device everywhere it's
easy to use dev_* functions to print messages instead of plain printks.
Where dev_* cannot be used printks are converted to pr_*.

pps: access pps device by direct pointer2011-01-13T16:03:19ZAlexander Gordeev2011-01-13T01:00:51Zurn:sha1:5e196d34a776420278e4117b4742cd9d3f2350ed
Using device index as a pointer needs some unnecessary work to be done
every time the pointer is needed (in irq handler for example). Using a
direct pointer is much more easy (and safe as well).

Add a helper function to gather timestamps. This way clients don't have
to duplicate it.

Adds support, by using the PPS line discipline, for the PPS sources
connected with the CD (Carrier Detect) pin of a serial port.
