I was looking at your original patch together with varous other patchs
for the device in ChromeOS trees and I ended up with the following
version. Please take a look and shout if you see something wrong.
The SMbus portion is untested as I do not have hardware; I2C does work
on actual hardware.
Thanks.

Input: driver for Elan I2C/SMbus touchpad
From: Duson Lin <dusonlin@emc.com.tw>
This driver supports Elan I2C/SMbous touchpads found in some laptops and
also in many Chromebooks.

+Elantech I2C Touchpad
+
+Required properties:
+- compatible: must be "elan,i2c_touchpad".
+- reg: I2C address of the chip.
+- interrupt-parent: a phandle for the gpio controller (see interrupt
+ binding[0]).
+- interrupts: (gpio) interrupt to which the chip is connected (see interrupt
+ binding[0]).
+
+Optional properties:
+- wakeup-source: touchpad should be configured as a wakeup source.
+- pinctrl-names: should be "default" (see pinctrl binding [1]).
+- pinctrl-0: a phandle pointing to the pin settings for the device (see
+ pinctrl binding [1]).
+- vcc-supply: a phandle for the regulator supplying 3.3V power.

* Re: [PATCH] HID: rmi: Scan the report descriptor to determine if the device is suitable for the hid-rmi driver

I am going to leave for XDC 2014 next week and then I'll have one week
off, so I prefer sending my impressions now (or it will have to wait 2
more weeks).
I am not sure this solution is sustainable in the long term. If every
driver starts checking each vendor collection in core, there is no point
in having core and drivers separated.
Unfortunately, I can not think of an easier way of doing it. So I think
(but Jiri can choose to ignore me) that we should at least hold this
until 3.19 development starts.

Maybe you should consider defining:
#define HID_SCAN_FLAGS_RMI HID_SCAN_FLAG_VENDOR_SPECIFIC | \
HID_SCAN_FLAG_RMI_WRITE | \
HID_SCAN_FLAG_RMI_INPUT_READ | \
HID_SCAN_FLAG_RMI_OUTPUT_READ | \
HID_SCAN_FLAG_RMI_ATTN | \
HID_SCAN_FLAG_RMI_MODE
and then just test:

I guess this one should be BIT(4) and the two after should be shifted by
one too.

What's the status of this series? Is it queued for 3.18 already?
I'm on H730, and these patches work nicely here. Would be great being
able to use a distro kernel at some point...

I don't see them in next yet:
http://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/log/drivers/input/mouse/elantech.c
I agree it would be nice to get these into 3.18.
Dmitry, what is the plan here ?

* Perixx reprogrammable mouse
From: Vincenzo Scotti @ 2014-10-05 10:59 UTC (permalink / raw)
To: linux-input
Hello.
I just bought some new mouses from Perixx MX's series. They work out of the
box with usbhid, even though they don't have an official driver under Linux to
remap buttons, and online I couldn't find anything useful.
So I was planning as a spare time project to write some sort of driver.
I read that usbmon could be useful to understand the protocol, if using
something like a Virtualbox VM with Windows running on it.
Given that, would it be better to make the driver as a kernel module, or as a
userspace application? I couldn't find any reprogrammable mouse driver in the
kernel drivers directory.
I think that the more games will be ported to Linux, the more we'll need soon
to have some support for this gamers-equipment.
I hope you'll give me some hints.
Regards,
Vincenzo.

usbmon + tshark for capture, and wireshark for analysis is the best way
I found.

What features do the devices offer? Something like auto-fire, latch
mode and so on?
I guess a userspace command line tool (maybe based on libusb) + udev
hooks to load a stored configuration would be enough for a prototype.
If later you want to load per-user configurations automatically you may
end up writing your own daemon/applet using libudev.

s/_/-/ in DT strings and property names plase.
The name seems very generic, and you mention the driver supports a
variety of touchpads. Please choose a specific device name for the
compatible string. Other devices can have that as a fallback entry in
addition to a more specific string.

If this is an interrupt from the PoV of this device, it doesn't matter
if the other end is connected to a hardwired interrupt controller or a
gpio. So drop the mention of GPIOs frmom the interrupt properties.

Input: evdev - fix EVIOCG{type} ioctl
From: Dmitry Torokhov <dmitry.torokhov@gmail.com>
The 'max' size passed into the function is measured in number of bits
(KEY_MAX, LED_MAX, etc) so we nedd to convert it accoidingly before tyring
to copy the data out, otherwise we will try copying too much and end up
with up with a page fault.
