HID: use debugfs for report dumping descriptor

2009-06-12T13:20:55+00:00

It is a little bit inconvenient for people who have some non-standard
HID hardware (usually violating the HID specification) to have to
recompile kernel with CONFIG_HID_DEBUG to be able to see kernel's perspective
of the HID report descriptor and observe the parsed events. Plus the messages
are then mixed up inconveniently with the rest of the dmesg stuff.

This patch implements /sys/kernel/debug/hid//rdesc file, which
represents the kernel's view of report descriptor (both the raw report
descriptor data and parsed contents).

With all the device-specific debug data being available through debugfs, there
is no need for keeping CONFIG_HID_DEBUG, as the 'debug' parameter to the
hid module will now only output only driver-specific debugging options, which has
absolutely minimal memory footprint, just a few error messages and one global
flag (hid_debug).

We use the current set of output formatting functions. The ones that need to be
used both for one-shot rdesc seq_file and also for continuous flow of data
(individual reports, as being sent by the device) distinguish according to the
passed seq_file parameter, and if it is NULL, it still output to kernel ringbuffer,
otherwise the corresponding seq_file is used for output.

The format of the output is preserved.

HID: move connect quirks

2008-10-14T21:50:56+00:00

Move connecting from usbhid to the hid layer and fix also hidp in
that manner.
This removes all the ignore/force hidinput/hiddev connecting quirks.

HID: move usage input mapping to hid.h

2008-10-14T21:50:49+00:00

This mapping are currently used on 2 placces and will be needed by more
quirk drivers, so move them to hid.h to allow them to use it.

HID: hid, make parsing event driven

2008-10-14T21:50:48+00:00

Next step for complete hid bus, this patch includes:
- call parser either from probe or from hid-core if there is no probe.
- add ll_driver structure and centralize some stuff there (open, close...)
- split and merge usb_hid_configure and hid_probe into several functions
  to allow hooks/fixes between them
