Thanks Fengguang for the patch, will take it.
However, the file drivers/input/touchscreen/atmel_mXT224E.c is not used
for mainline kernel.
Xuwei will remove git://github.com/hisilicon/linux-hisi
integration-hilt-linux-linaro.
Sorry for the confusion.

Yes as mentioned in thread it does not seem possible to write a
hwdb-rule that works for both US and non-US keyboard. Also it is a
general problem that affects other keyboards than Corsair, again see
previous mails in this thread.
David, it would be great if you could get your patch ready so this one
could be closed. If you don't have the time to do it, perhaps my
original patch could be considered again. I fully aggree that it is a
hack but it does solve the problem with little risk of bad side
effects. It can always be removed later we you have a proper fix.

Fredrik

The proposed changes look good, and I've given them a test-spin and everything

Also psmouse-base.c call psmouse_reset between alps_detect() and
alps_init(). We must do trackstick detection after psmouse_reset,
but intorducing another psmouse_reset in alps_detect() will slow
down initialization for ALPS devices. Also do not remember that
psmouse_reset will lock both keyboard & mouse for one second
(sometimes for two) on my laptop. I played with this and I think
my patch is good approach how to do trackstick detection without
slowdown or other side effects.
Also we do not need to know if ALPS touchpad has trackstick
device in alps_detect() phase. In alps_detect() we just need to
know if PS/2 device is ALPS or not. From psmouse/serio point of
view there is only one ALPS device on PS/2/i8042 bus. Just
alps.ko driver parse PS/2 packets and detect which packet has
touchpad header and which trackpoint. So we really do not need to
know if trackstick is there or not in alps_detect() function.

This whole test can be replace by a field in rmi_id (.driver_data) as

Nitpicking, I'd prefer having the most generic one at the end. In case
you need to specify other flags to some specific devices, they will have
to be inserted before the catchall rule, so let's start now :).

Just to be sure, could you also add in the commit message that the flag
RMI_DEVICE_HAS_PHYS_BUTTONS is not auto-detected by the driver and that
it has to be added manually when adding a device to rmi_id[].
BTW, you can use .driver_data in in struct hid_device_id to pass the
flags directly. So here, it would be nice to add such retrieval in
probe:
data->device_flags = id->driver_data;
and then check for RMI_DEVICE.

I think here you will get a reset for each button press. I believe the
mouse collection is pretty generic and you should also get the relX|Y
events with the button press.

Hi Andrew,
That's a good job on this series. I like it better than the previous one.
I have a concern in 2/3 and a nitpick in 3/3.
But this one (1/3) is

While you are at sending patches to fix hid-rmi, could you also try to
use hid_report_len() instead of manually computing the size (in a
separate patch if possible)?
I think the result should be the same, but I'd prefer you to double
check.

Actually no it doesn't. The gcc output shows that neither -Wtype-limits
nor -Wextra are used to compile that file. I assume this is because
there would be just too many warnings.

Have hid-rmi handle all of the Razer Blade HID devices that are part of the
composite USB device. This will allow hid-rmi to operate the touchpad in rmi
mode while passing events from the other devices to hid-input.

From: Andrew Duggan @ 2014-12-19 22:45 UTC (permalink / raw)

In-Reply-To: <1419029143-20484-1-git-send-email-aduggan@synaptics.com>
The external buttons on HID touchpads are connected as pass through devices and
button events are not reported in the rmi registers. As a result on these
devices we need to allow the HID generic desktop button events to be processed
by hid-input.

* [PATCH 1/3] HID: rmi: Support non rmi devices by passing events to hid-input
From: Andrew Duggan @ 2014-12-19 22:45 UTC (permalink / raw)
To: linux-input, linux-kernel; +Cc: Andrew Duggan, Jiri Kosina, Benjamin Tissoires
Allowing hid-rmi to bind to non rmi devices allows us to support composite USB
devices which contain several HID devices one of which is a HID touchpad.
Since all of the devices have the same VID and PID we can add the device
to the hid_have_special_driver list and have hid-rmi handle all of the devices.
Then hid-rmi's probe can look for the rmi specific HID report IDs and decide if
it should handle the device as a rmi device or simply report that the events
needs additional processing.
Signed-off-by: Andrew Duggan <aduggan@synaptics.com>

This patch series is my second attempt at getting the hid-rmi driver working on
the Razer Blade 14 based on Benjamin's comments. I decided to break it up into
three separate patches. This one allows hid-rmi to bind to all of the devices.
Instead of adding a quirk I just look at the report IDs to see if it should
do rmi or not.

This patchset contains initial support for the touchscreen on the Broadcom
iProc family of SoCs. This driver has been validated with Cygnus and is expected
to work on other iProc family of SoCs that use the same touchscreen controller.
Changes from v1:
- Add missing newlines to debug messages
- Use BIT macro for defines
- Fix logic in get_tsc_config to improve readability
- Get rid of unnecessary remove() function

+* Broadcom's IPROC Touchscreen Controller
+
+Required properties:
+- compatible: must be "brcm,iproc-touchscreen"
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- clocks: The clock provided by the SOC to driver the tsc
+- clock-name: name for the clock
+- interrupts: The touchscreen controller's interrupt
+
+Optional properties:
+- scanning_period: Time between scans. Each step is 1024 us. Valid 1-256.
+- debounce_timeout: Each step is 512 us. Valid 0-255
+- settling_timeout: The settling duration (in ms) is the amount of time
+ the tsc waits to allow the voltage to settle after
+ turning on the drivers in detection mode.
+ Valid values: 0-11
+ 0 = 0.008 ms
+ 1 = 0.01 ms
+ 2 = 0.02 ms
+ 3 = 0.04 ms
+ 4 = 0.08 ms
+ 5 = 0.16 ms
+ 6 = 0.32 ms
+ 7 = 0.64 ms
+ 8 = 1.28 ms
+ 9 = 2.56 ms
+ 10 = 5.12 ms
+ 11 = 10.24 ms
+- touch_timeout: The continuous number of scan periods in which touch is
+ not detected before the controller returns to idle state.
+ Valid values 0-255.
+- average_data: Number of data samples which are averaged before a final
+ data point is placed into the FIFO
+ Valid values 0-7
+ 0 = 1 sample
+ 1 = 2 samples
+ 2 = 4 samples
+ 3 = 8 samples
+ 4 = 16 samples
+ 5 = 32 samples
+ 6 = 64 samples
+ 7 = 128 samples
+- fifo_threshold: Interrupt is generated whenever the number of fifo
+ entries exceeds this value
+ Valid values 0-31
+- ts-rotation: Touch screen controller and display panel orientation angle.
+ 0 = Tsc x_min y_min placed at LCD x_min y_min. None
+ 1 = Tsc x_min y_max placed at LCD x_min y_min. 90 degrees
+ 2 = Tsc x_max y_max placed at LCD x_min y_min. 180 degrees
+ 3 = Tsc x_max y_min placed at LCD x_min y_min. 270 degrees

+
+ touchscreen: tsc@0x180A6000 {

You can also drop the remove() code since we clear drvdata automatically and
input device is managed so does not need to be unregistered explicitly.
Thanks.

* Re: [PATCH] Handle spurious backslash key repeats on some keyboards
From: RH @ 2014-12-19 16:28 UTC (permalink / raw)
To: linux-input
In-Reply-To: <CAMsZVf-2_eFKoqgO1+bEB4ziA1e9-z4rYviy_r9ksjmAUAe5Sg@mail.gmail.com>
Hello,
I experience the same issue with my new keyboard:
*Corsair Raptor K30 (German version)*
The issue can be fixed/worked around with this rule in hwdb:
---------------
#keyboard:name:*Corsair*:dmi:bvn*:bvr*:bd*:svn*:pn*:pvr*
keyboard:usb:v1B1Cp1B0A*
KEYBOARD_KEY_70031=reserved
---------------
So you think the US version won't work with this anymore? I guess they
will send both scancodes, too.
This is the output of lsusb:

Did you already find someone with a US keyboard? Shall I write in the
corsair forums or to the support to find out whether US keyboards have
the same product IDs? If this is not the case, we could safely use vendor/
product IDs for the workaround.
I'd really like to submit working hwdb lines to the udev database to save
other users from having these troubles.
Also, do you know why
Greetings,

This is most likely fallout from the G_FMT failure above. If you fix that,
then this should be OK.

OK, 3.16 explains the PRIO failure. For that kernel you need to set this
flag in struct video_device:
set_bit(V4L2_FL_USE_FH_PRIO, &vdev->flags);
This flag went away in 3.17 or 3.18 since it has now become standard behavior.

drivers/media remains under heavy development, so for video capture drivers
like yours you should always patch against either the mainline linux tree
or (preferred) the media_tree.git repo (git://linuxtv.org/media_tree.git,
master branch).

Thanks for flagging this up. The patch I submitted is written against the
Android touch devices spec, which treats ABS_MT_PRESSURE being zero as
hover, but indeed currently the handling of BTN_TOUCH when using
input_mt_report_pointer_emaultion() won't be quite right.
I will have a look at straightening this out and re-post.
cheers

Driver code is attached (should be identical to the one from initial
mail). Kernel version used for the tests is 3.16.0-25 from Ubuntu
Utopic, git tree for patches is currently
https://git.kernel.org/pub/scm/linux/kernel/git/dtor/input.git
I'm building the module standalone on the target machine, since it's not
powerful enough that you would want to do a full kernel build. However,
since the driver was merged into mainline, no other changes have been
made, so I think it shouldn't be a problem to patch against the original
git tree?
Best, Florian
