HID: core: reset the quirks before calling probe again

2018-03-23T14:46:09+00:00

Given that now the quirk handling is done in hid-quirk.c, we can actually
reset the quirks before calling .probe(), so that the drivers do not need
to keep track of initial quirks.

HID: multitouch: do not set HID_QUIRK_NO_INIT_REPORTS

2018-03-23T14:46:09+00:00

It is set by default now, so there is no point setting it in the driver

HID: core: remove the need for HID_QUIRK_NO_EMPTY_INPUT

2018-03-23T14:44:57+00:00

There is no real point of registering an empty input node.
This should be default, but given some drivers need the blank input
node to set it up during input_configured, we need to postpone
the check for hidinput_has_been_populated().

HID: multitouch: remove dead zones of Razer Blade Stealth

2018-03-23T14:44:57+00:00

The Razer Blade Stealth detects palms too aggressively and this creates
a dead zone around the touchpad. Users like being able to use their
entire touchpad, so we should probably not filter out the "palm" events
from the device and report them as regular touches, leaving the palm
detection up to the upper stack

HID: multitouch: export a quirk for the button handling of touchpads

2018-03-23T14:44:57+00:00

Instead of using the class name, we better have a specific quirk for it
so other classes can make use of it.

HID: Fix hid_report_len usage

2018-02-16T12:30:56+00:00

Follow the change of return type u32 of hid_report_len,
fix all the types of variables those get the return value of
hid_report_len to u32, and all other code already uses u32.

HID: hid-multitouch: support fine-grain orientation reporting

2017-12-01T09:01:01+00:00

The current hid-multitouch driver only allow the report of two
orientations, vertical and horizontal. We use the Azimuth orientation
usage 0x3F under the Digitizer usage page to report orientation if the
device supports it.

Changelog:
  v1 -> v2:
   - Fix commit message.
   - Remove resolution reporting for ABS_MT_ORIENTATION.
  v2 -> v3:
   - Fix commit message.
  v3 -> v4:
   - Fix ABS_MT_ORIENTATION ABS param range.
   - Don't set ABS_MT_ORIENTATION in ABS_DG_HEIGHT when it is already
     set by ABS_DG_AZIMUTH.
  v4 -> v5:
   - Improve multi-touch-protocol.rst documentation.
