Add support for the 15'' MacBook Pro Retina. The keyboard is
the same as recent models.
The patch needs to be synchronized with the bcm5974 patch for
the trackpad - as usual.
Patch originally written by clipcarl (forums.opensuse.org).

Since commit 1c6c69525b ("genirq: Reject bogus threaded irq requests")
threaded IRQs without a primary handler need to be requested with
IRQF_ONESHOT, otherwise the request will fail. This patch adds the
IRQF_ONESHOT to input drivers where it is missing. Not modified by
this patch are those drivers where the requested IRQ will always be a
nested IRQ (e.g. because it's part of an MFD), since for this special
case IRQF_ONESHOT is not required to be specified when requesting the
IRQ.

rep_data is not an array anymore, so taking it's address when passing to
wacom_get_report() is wrong.

Keymaps used by drivers based on matrix-keymap facilities are arrays of
unsigned shorts, not chars. Treating them otherwise produces corrupted
keymaps.

When platform keymap is not supplied to matrix_keypad_build_keymap()
and device tree support is enabled, try locating specified property
and load keymap from it. If property name is not defined, try using
"linux,keymap".

Change matrix-keymap helper to be out-of-line, like sparse keymap,
allow the helper perform basic keymap validation and return errors,
and prepare for device tree support.

Subject: [PATCH] Input: omap-keypad: dynamically handle register offsets
Keypad controller register offsets are different for omap4
and omap5. Handle these offsets through static mapping and
assign these mappings during run time.
Tested on omap4430 sdp with 3.4-rc3.
Tested on omap5430evm with 3.1-custom kernel.

This patch adds semi-MT support for ALPS v4 protocol touchpads.
It is based on the work by Seth Forshee for ALPS v3 and v4 protocol
support. Three packets are required to assemble and process the MT
data. ST events are reported at once to avoid latency. If there
were two contacts or more, report MT data instead of ST events.
Thanks to Seth Forshee for providing most of the code, guidance
and insight for producing this patch.

This driver adds support for the Synaptics NavPoint touchpad connected
to a PXA27x SSP port in SPI slave mode. The device emulates a mouse;
a tap or tap-and-a-half drag gesture emulates the left mouse button.
For example, use the xf86-input-evdev driver for an X pointing device.

According to the standard count 0 is special - no IO should happen but we
can check error conditions (device gone away, etc), and return 0 if there
are no errors. We used to return -EINVAL instead and we also could return 0

When copy_to/from_user fails in the middle of transfer we should not
report to the user that read/write partially succeeded but rather
report -EFAULT right away, so that application will know that it got
its buffers all wrong.
If application messed up its buffers we can't trust the data fetched
from userspace and successfully written to the device or if data read
from the device and transferred to userspace ended up where application
expected it to end.
If serio_write() fails we still going to report partial writes if failure
happens in the middle of the transfer.
This is basically a revert of 7a0a27d2ce38aee19a31fee8c12095f586eed393
and 4fa0771138d0b56fe59ab8ab3b1ce9e594484362.

its already done in X path.

that requests tablets to send Wacom Touch packets for
