Revert "HID: multitouch: Support ALPS PTP stick with pid 0x120A"

2017-10-02T09:49:43+00:00

This reverts commit fcaa4a07d2a4b541e91da7a55d8b3331f96d1865.

As noted by Masaki [1], 0x120A + trackpoint will not be used in mass
production machines, so remove the ID accordingly.

HID: multitouch: constify attribute_group structures.

2017-08-03T11:38:29+00:00

attribute_group are not supposed to change at runtime. All functions
working with attribute_group provided by  work with
const attribute_group. So mark the non-const structs as const.

HID: multitouch: use proper symbolic constant for 0xff310076 application

2017-08-03T09:25:32+00:00

0xff310076 application has been defined by 957b8dffa4e3d1 ("HID: multitouch:
Support Asus T304UA media keys") as a vendor-specific application with
symbolic constant HID_VD_ASUS_CUSTOM_MEDIA_KEYS, so let's make use of
it.

HID: multitouch: Support Asus T304UA media keys

2017-08-03T09:20:17+00:00

The Asus T304UA convertible sports a magnetic detachable keyboard with
touchpad, which is connected over USB. Most of the keyboard hotkeys are
exposed through the same USB interface as the touchpad, defined in the
report descriptor as follows:

0x06, 0x31, 0xFF,  // Usage Page (Vendor Defined 0xFF31)
0x09, 0x76,        // Usage (0x76)
0xA1, 0x01,        // Collection (Application)
0x05, 0xFF,        //   Usage Page (Reserved 0xFF)

0x85, 0x5A,        //   Report ID (90)
0x19, 0x00,        //   Usage Minimum (0x00)
0x2A, 0xFF, 0x00,  //   Usage Maximum (0xFF)
0x15, 0x00,        //   Logical Minimum (0)

0x81, 0x02,        //   Input (Data,Var,Abs,No Wrap,Linear,Preferred State,No Null Position)
0xC0,              // End Collection

This UsagePage is declared as a variable, but we need to treat it as an
array to be able to map each Usage we care about to its corresponding
input key.

HID: multitouch: do not blindly set EV_KEY or EV_ABS bits

2017-07-13T14:48:29+00:00

Now that input core insists on having dev->absinfo when device claims to
generate EV_ABS in its dev->evbit, we should not be blindly setting that
bit.

The code in question might have been needed before input_set_abs_params()
started setting EV_ABS in device's evbit, but not anymore, and is now
breaking devices such as SMART SPNL-6075 Touchscreen.
