8a7ae2a890 Input: xpad - add more xbox 360 controller ids
Add Mad Catz and 0x0e6f xbox360 controllers which are already found
in xpad_device[] table in xpad.c into the vendor id list. Also add
Logitech into the vendor list for Logitech Chillstream gamepads.
Also add the RedOctane Guitar Hero X-plorer.

97f09cb53d Input: xpad - fix inverted Y and RY axes
The commit ae91d10aab inverted Y and RY
axes on xbox360 so that up is positive and down is negative.
This is wrong, as axes on game controllers have up as negative per
convention. Also, even xpad itself reports HAT0X with up as negative.

Fix that by inverting them again.

Also, according to http://bugzilla.kernel.org/show_bug.cgi?id=10337 the
original xbox controllers also have the Y and RY axes inverted.
Fix that by inverting them as well.

a0979923d7 Input: xpad - fix dpad handling of unknown devices
For devices not specifically listed in xpad.c, xpad->dpad_mapping
is initially set to MAP_DPAD_UNKNOWN. In xpad_probe() it gets changed
to either MAP_DPAD_TO_BUTTONS or MAP_DPAD_TO_AXES, depending on the
module parameter dpad_to_buttons.

However, MAP_DPAD_UNKNOWN is defined as -1, while the field is u8.
This results in actual value of 255, causing the MAP_DPAD_UNKNOWN
check in xpad_probe() to fail.
Fix that by defining MAP_DPAD_UNKNOWN as 2 instead.

Also, setting module parameter dpad_to_buttons to 1 should obviously
map dpad to buttons, while the default behaviour (0) should be to map
dpad to axes. However, dpad_to_buttons is directly assigned to
xpad->dpad_mapping, and as MAP_DPAD_TO_BUTTONS is 0, the actual
behaviour is reversed.
Fix that by negating dpad_to_buttons in assignment.

8a0f83eacc Input: xpad - match xbox 360 devices with interface info
Match Xbox 360 controllers using the interface info, i.e. interface
class 255 (Vendor specific), subclass 93 and protocol 1, instead of
specifying the device ids individually. As the class is vendor-specific,
we have to still match against vendor id as well, though.

589499c04b ixp4xx-beeper: add MODULE_ALIAS
The following patch allows ixp4xx-beeper to be loaded by udev
automatically when compiled as a module with kernel versions 2.4.24 and
greater.

This patch is required because 43cc71eed1
("platform: prefix MODALIAS with "platform:"") changed the modalias
string to have the extra prefix.

LKG7102D7:~# udevinfo -a -p /sys/devices/platform/ixp4xx-beeper.4

 looking at device '/devices/platform/ixp4xx-beeper.4':
   KERNEL=="ixp4xx-beeper.4"
   SUBSYSTEM=="platform"
   DRIVER==""
   ATTR{modalias}=="platform:ixp4xx-beeper"

udev therefore tries to modprobe platform:ixp4xx-beeper instead of
ixp4xx-beeper.

LKG7102D7:~# udevtest /sys/devices/platform/ixp4xx-beeper.4
...
import_uevent_var: import into environment: 'PHYSDEVBUS=platform'
import_uevent_var: import into environment: 'MODALIAS=platform:ixp4xx-beeper'

appeared after 0 loops
main: run: 'socket:/org/kernel/udev/monitor'
main: run: '/sbin/modprobe --use-blacklist platform:ixp4xx-beeper'

With this patch, depmod adds an alias line (see below) to
modules.alias which allows modprobe to load the right module.

alias platform:ixp4xx-beeper ixp4xx-beeper

Some platforms do require this to be tuned, instead of the default

Rotary encoder will always use zero debounce time for now to achieve
certain sensitivity.

1. use ioremap() for registers access, this improves the portability
   of the driver (e.g. same IP on different processor with different
   I/O memory range), and make it possible to remove those registers
   definition in pxa-regs.h as PXA is undergoing a clean-up of that
   header file

2. use device specific IRQ instead of hardcoded IRQ_KEYPAD, same
   reason as above

3. clean up the error handling path in _probe()

4. remove DRIVER_NAME and use pdev->name when necessary, we don't
   actually need a constant string literals

62059d9e91 Input: pxa27x_keypad - enable rotary encoders and direct keys
1. Rotary encoder events can be configured either as relative events
   as the legacy code does or as any specified key code, this is
   useful on some platform which uses the rotary keys as
   KEY_{UP/DOWN/LEFT/RIGHT}

2. Add support for direct keys, the corresponding keycodes for each
   direct key can now be specified within the platform data

3. Remove the direct/rotary key detection code from the IRQ handler
   to dedicated functions to improve readability

d7416f9eaa Input: pxa27x_keypad - introduce pxa27x_keypad_config()
Introduce pxa27x_keypad_config() for keypad registers configuration
and remove the reg_kpc, reg_kprec from platform data structure
so that configurations of keypad registers can be centralized to a
single function.

It can also be re-used when resuming.

1814db6969 Input: pxa27x_keypad - introduce driver structure and use KEY() to define matrix keys
1. Introduce the "struct pxa27x_keypad" structure for driver specific
    information, such as "struct clk", generated matrix key codes and
    so on

 2. Use KEY() macro to define matrix keys, instead of original 8x8 map
    this makes definition easier with keypad where keys are sparse

 3. Keep a generated array in "struct pxa27x_keypad" for fast lookup

 4. Separate the matrix scan into a dedicated function for readability
    and report only those keys whose state has been changed, instead
    of report all states

 5. Make use of KPAS to decide the faster path if only one key has been
    detected

1a1cd739a4 Input: pxa27x_keypad - remove pin configuration from the driver
The pin configurations will slowly be moved to the board specific code
at initialization thus to make the driver more generic.
