Hi Dmitry,
a potential consumer could be Android and Android IMEs, this would add
the ability for a HID device to select and control the suggested words
in the word prediction system when typing.

Does this need to go in with the other patches in the set?
I'm _guessing_ that, as you've sent them separately, they can be
applied separately?
This needs to go in via MFD, but for my own reference:

As review request #42 has been approved, I don't really have strong
objections to adding this, as it means certain level of standardization by
he USB Device Working Group HID Committee.
Dmitry, given your question, I am not applying the patch yet and waiting
for your consideration/Ack.

* Re: ASUS N550JK Touchpad recognized wrongly as PS/2 mouse
From: Benjamin Tissoires @ 2014-10-20 15:38 UTC (permalink / raw)
To: Carla Rosenfield, Hans de Goede; +Cc: linux-input

Hi Carla,
just FYI, I have the same laptop model than you, and can reproduce
your bug report in the same way. I'll work on that to make it working
properly.
Hans, (unfortunately,) this laptop has a ETD0105 touchpad from Elan.
That means that we do not have the X550 touchpad in house, but also
means that we should be able to get in working faster than the X550
one :)
Cheers,
Benjamin

Ok, so 2 things:
1) On the ETD0105 touchpad not working, does the kernel you're using
already have this patch ? :
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/input/mouse/elantech.c?id=271329b3c798b2102120f5df829071c211ef00ed
If not, try that, if it does, it may need some tweaks to that patch,
or something similar.
2) On not having an X550 style touchpad, I got a report from a user
in the bugzilla tracking that, telling us that he is busy reverse
engineering the protocol, and is making good progress, so that one
should hopefully get sorted out soon-ish too :)

Hans

Please merge with my Ack for the new codes - I was not against adding them,
just wanted to make sure they are going to be used instead of just adding them
as placehoders.
Thanks.

That was my understanding, but I wanted to be sure.

I tried the RHEL 6.6 kernel (the only I had on a usb disk handy at that time).
The Fedora 21 snapshot (3.17.0) makes it detected properly :)
However, landing 8 fingers on the touchpad makes it completely lost
(waiting few seconds without touching it is enough to get it back
alive).

I saw that on the bug too. Hopefully, it will work out well.

Good.

Hmm, might be a firmware bug, but this also might mean it can detect
more fingers then previous versions, and sends a new packet type when
more then X fingers are present, we should probably end a mail to
our contacts at elantech about this. Since you've the hardware I
assume you will be sending such a mail ?

* [PATCH v2 0/4] input: Add new sun4i-lradc-keys driver
From: Hans de Goede @ 2014-10-21 8:24 UTC (permalink / raw)

Hi All,
After a bit of a pause due to -ENOTIME, here is my 2nd attempt at getting
support for the lradc attached tablet keys found one some Allwinner boards
upstream.
I've dubbed this v2 even though there has been more then one version before
because I've lost count, and as said this represents the 2nd attempt at getting
this upstream.
The major change from the previous attempt is that now the devicetree
description has one subnode per key just like gpio-keys has.
I hope this version is to everyones liking and can be merged soon :) The intend
is for the actual driver to go upstream through Dmitry's tree, where as the
3 dts patches should go upstream through Maxime's tree.
Thanks & Regards,
Hans

Allwinnner sunxi SoCs have a low resolution adc (called lradc) which is
specifically designed to have various (tablet) keys (ie home, back, search,
etc). attached to it using a resistor network. This adds a driver for this.
There are 2 channels, currently this driver only supports chan0 since there
are no boards known to use chan1.
This has been tested on an olimex a10s-olinuxino-micro, a13-olinuxino, and
a20-olinuxino-micro.

Changes in v2:
-Change devicetree bindings to use a per key subnode, like gpio-keys does

It really depends. If you have driver for serial port, you don't need
to describe what goes over the serial port. But documentation would be
nice.

As well as not going upstream because there is no way anyone else can
test changes to the code, or support it. Plus of course there are those
awkward questions around derivative work boundaries that it is best the
base kernel keeps well clear of.
If the data format is documented to the point someone can go write their
own touch processor for the bitstream then that really deals with it
anyway. Given the number of these things starting to pop up it would
probably be good if someone did produce an open source processing engine
for touch sensor streams as it shouldn't take long before its better than
all the non-free ones 8).
Given how latency sensitive touch is and the continual data stream I
would be inclined to think that the basic processing might be better in
kernel and then as an input device - providing it can be simple enough to
want to put kernel side.
Otherwise I'd say your bitstream is probably something like ADC data and
belongs in IIO (which should also help people to have one processing
agent for multiple designs of touch, SPI controllers etc)

I do not think you really want KEY_HOME (go to the beginning of the

Thank you for this input, I will feed it back.

I would think that a touch processing algorithm (including aspects such as
noise and false touch suppression, etc) would be too complex to live
in-kernel. Getting decent performance on a particular device requires a lot
of tuning/customisation.

This sounds promising. The only sticking point I can see is that a touch
frontend has many more channels (possibly thousands), which would seem to
impose a lot of overhead when put into the IIO framework. I will certainly
take a closer look at it.

You're still using the old pattern for the compatible here, it should
be allwinner,sun4i-a10-lradc-keys.

I guess the node address in centivolts aren't really that common,
maybe in mV instead?

* Plantronics Telephony Device HID Driver
From: Cole, JD @ 2014-10-21 18:40 UTC (permalink / raw)
To: linux-input@vger.kernel.org
Cc: Wesselman, Tom, Dsouza, Sunil, Junge, Terry, dtor@chromium.org,
bleung@chromium.org, vpalatin@chromium.org, adlr@chromium.org
Plantronics telephony devices equipped with HID-enabled controls have been reported to cause odd mouse behaviors when buttons are clicked. This is due to how the hid-input driver handles "unmapped" usages and the fact that Plantronics devices send Vendor Unique usages in addition to standards, e.g. Consumer Page Mute. It is the vendor unique usages that are mis-interpreted by the hid-input driver and mapped as mouse events.
This driver serves to prevent unhandled usages from reaching the hid-input driver. Two patches are included:
(1) The minimal driver
(2) The more complete additions to hid.h Consumer Page MACROS
Cheers,
jd

From: JD Cole <jd.cole@plantronics.com>
Date: Fri, 17 Oct 2014 12:21:49 -0700
Subject: [PATCH 1/2] Created base Plantronics HID driver.
A fix for Plantronics telephony device controls interfering with
the mouse.
This version of the driver prevents Telephony pages which are not
mapped as Consumer Control applications AND are not on the Consumer Page
from being registered by the hid-input driver.
BUG=chromium:417434
TEST=Tested with multiple Plantronics devices on 'peppy' Acer C720p.

I can understand where you're coming from, but KEY_HOME is what these
keys typically send under android, and what android expects them to
send...
Not sure if that is a good argument to keep it as KEY_HOME though.
Please let me know which way you want this key to be mapped, and
I'll update it for the next version.
Regards,
Hans
