Input: usbtouchscreen - initialize eGalax devices

2012-09-05T05:17:56+00:00

Certain eGalax devices expose an interface with class HID and protocol
None.  Some work with usbhid and some work with usbtouchscreen, but
there is no easy way to differentiate.  Sending an eGalax diagnostic
packet seems to kick them all into using the right protocol for
usbtouchscreen, so we can continue to bind them all there (as opposed to
handing some off to usbhid).

This fixes a regression for devices that were claimed by (and worked
with) usbhid prior to commit 139ebe8dc80dd74cb2ac9f5603d18fbf5cff049f
("Input: usbtouchscreen - fix eGalax HID ignoring"), which made
usbtouchscreen claim them instead.  With this patch they will still be
claimed by usbtouchscreen, but they will actually report events
usbtouchscreen can understand.  Note that these devices will be limited
to the usbtouchscreen feature set so e.g. dual touch features are not
supported.

I have the distinct pleasure of needing to support devices of both types
and have tested accordingly.

USB: input: usbtouchscreen.c: fix up dev_* messages

2012-05-04T22:33:16+00:00

Previously I had made the struct device point to the input device, but
after talking with Dmitry, he said that the USB device would make more
sense for this driver to point to.  So converted it to use that instead.

USB: usbtouchscreen.c: remove dbg() usage

2012-05-02T04:33:23+00:00

dbg() was a very old USB-specific macro that should no longer
be used. This patch removes it from being used in the driver
and uses dev_dbg() instead.

USB: input: usbtouchscreen.c: fix up dev_err() usage

2012-05-02T00:57:11+00:00

We should always reference the input device for dev_err(), not the USB
device.  Fix up the places where I got this wrong.

USB: usbtouchscreen.c: remove err() usage

2012-04-25T21:48:46+00:00

err() was a very old USB-specific macro that I thought had
gone away.  This patch removes it from being used in the
driver and uses dev_err() instead.

Merge commit 'v3.3-rc6' into next

2012-03-09T18:55:17+00:00

Input: usbtouchscreen - add support for Data Modul EasyTouch TP 72037

2012-03-04T18:45:13+00:00

The Data Modul TP 72037 EasyTouch controller is derived from EGALAX
controller and is capable of detecting dual contacts. Packets can be 5
bytes or 10 bytes long, depending whether one or two contacts are
detected. Format is same as EGALAX touch controller, but with x and y
coordinates inverted.

module_param: make bool parameters really bool (drivers & misc)

2012-01-12T23:02:20+00:00

module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

USB: convert drivers/input/* to use module_usb_driver()

2011-11-18T17:48:31+00:00

This converts the drivers in drivers/input/* to use the
module_usb_driver() macro which makes the code smaller and a bit
simpler.

Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.
