Subject: [PATCH v2 0/4] ledtrig-tty: add new state evaluation

Changes in v2:
- rename new function from tty_get_mget() to tty_get_tiocm() as
requested by 'Jiri Slaby'.
- As suggested by 'Jiri Slaby', fixed tabs in function documentation
throughout the file '/drivers/tty/tty_io.c' in a separate commit.
- Move the variable definition to the top in function 'ledtrig_tty_work()'.
This was reported by the 'kernel test robot' after my change in v1.
- Also set the 'max_brightness' to 'blink_brightness' if no
'blink_brightness' was set. This fixes a problem at startup when the
brightness is still set to 0 and only 'line_*' is evaluated. I looked in
the netdev trigger and that's exactly how it's done there.

v1:
This is a follow-up patchset, based on the mailing list discussion from
March 2023 based on the old patchset v7 [1]. I have changed, the LED trigger
handling via the sysfs interfaces as suggested by Uwe Kleine-König.

Subject: [PATCH v2 4/4] trigger: ledtrig-tty: add new line mode to triggers

Until now, the LED blinks when data is sent via the tty (rx/tx).
The serial tty interface also supports additional input signals, that can
also be evaluated within this trigger. This change is adding the following
additional input sources, which could be controlled
via the '/sys/class/<leds>/' sysfs interface.

- line_cts:
DCE is ready to accept data from the DTE (Clear To Send). If the line
state is detected, the LED is switched on.
If set to 0 (default), the LED will not evaluate CTS.
If set to 1, the LED will evaluate CTS.

- line_dsr:
DCE is ready to receive and send data (Data Set Ready). If the line state
is detected, the LED is switched on.
If set to 0 (default), the LED will not evaluate DSR.
If set to 1, the LED will evaluate DSR.

- line_car:
DTE is receiving a carrier from the DCE (Data Carrier Detect). If the
line state is detected, the LED is switched on.
If set to 0 (default), the LED will not evaluate CAR (DCD).
If set to 1, the LED will evaluate CAR (DCD).

- line_rng:
DCE has detected an incoming ring signal on the telephone line
(Ring Indicator). If the line state is detected, the LED is switched on.
If set to 0 (default), the LED will not evaluate RNG (RI).
If set to 1, the LED will evaluate RNG (RI).

In addition to the new line_* entries in sysfs, the indication for the
direction of the transmitted data is independently controllable via the
new rx and tx sysfs entrie now too. These are on by default. Thus the
trigger behaves as before this change.

- rx:
Signal reception (rx) of data on the named tty device.
If set to 0, the LED will not blink on reception.
If set to 1 (default), the LED will blink on reception.

- tx:
Signal transmission (tx) of data on the named tty device.
If set to 0, the LED will not blink on transmission.
If set to 1 (default), the LED will blink on transmission.

For a v3 patch-set I will add the error message from build robot.

Build robot output of my v1 change:
https://lore.kernel.org/linux-leds/[email protected]/T/#m777371c5de8fadc505a833139b8ae69ac7fa8dab

I decided to move the variable definition with a separate commit
to the top of the function, to make the build robot happy. After that
I made my changes for v2 to the ledtrig-tty to add the feature.

The link you pasted above states:
=======
If you fix the issue in a separate patch/commit (i.e. not just a new
version of
the same patch/commit), kindly add following tags
| Reported-by: kernel test robot <[email protected]>
| Closes:
https://lore.kernel.org/oe-kbuild-all/[email protected]/
=======

So please follow that suggestion ;).

Ok, I understand, thanks will to this on a v3 patchset.
I will now wait for the comments of my changes in ledtrig-tty from the
led subsystem.
And then I will send a new patch set with the requested changes.

Sorry for the silly question. But do I have to send this patch again for
a v3?

If it is not picked up by Greg by then, I would send it with my rev-b

This series is long gone from my review queue, so a v3 will be needed at
the very least.

Yes, I want to ensure that the tty change is correct, last round I
didn't think it was...

Hello Lee,

I only got reviews for the fixes and preparations for commits that
change the
tty subsystem, but no reaction from the maintainer of the feature I want
to
add to ledtrig-tty for v1 and v2 patchset.

How should I proceed? Send a v3 with the the requested changes.

[Patch v2 1/4]:
https://lore.kernel.org/linux-leds/[email protected]/T/#m913d3822465f35b54dfa24b1dfe4d50e61352980
Change got a 'Reviewed-by: Jiri Slaby <[email protected]>'.
Will add this to an upcoming v3 again.

[Patch v2 2/4] :
https://lore.kernel.org/linux-leds/[email protected]/T/#m7ee7618894a66fd3c89bed488a2394265a3f8df1
I missed to add the robot error message to the commit message and also
missed
to add the the following 'Reported-by: kernel test robot
<[email protected]>' and
'Closes:
https://lore.kernel.org/oe-kbuild-all/[email protected]/'
to the commit message. Will add this to an upcoming v3.

And do not wait for the review of the following patches.
https://lore.kernel.org/linux-leds/[email protected]/T/#mc0ecb912fa0e59015ad0a9b4cb491ae9f18c1ea9

Yes. I've removed this from my queue.

Better to resend it with the fixes.
