Currently, the synaptics driver puts the device into Absolute mode.
As explained in the synaptics documentation section 3.2, in this mode,
the device sends a continuous stream of packets at the maximum rate
to the host when the user's fingers are near or on the pad or
pressing buttons, and continues streaming for 1 second afterwards.
These packets are even sent when there is no new information to report,
even when they are duplicates of the previous packet.

For embedded systems this is a bit much - it results in a huge
and uninterrupted stream of interrupts at high rate.

This patch adds support for Relative mode, which can be selected as
a new psmouse protocol. In this mode, the device does not send duplicate
packets and acts like a standard PS/2 mouse. However, synaptics-specific
functionality is still available, such as the ability to set the packet
rate, and rather than disabling gestures and taps at the hardware level
unconditionally, a 'synaptics_disable_gesture' sysfs attribute has
been added to allow control of this functionality.

This solves a long standing OLPC issue: synaptics hardware enables
tap to click by default (even in the default relative mode), but we
have found this to be inappropriate for young children and first
time computer users. Enabling the synaptics driver disables tap-to-click,
but we have previously been unable to use this because it also enables
Absolute mode, which is too "spammy" for our desires and actually
overloads our EC with its continuous stream of packets. Now we can enable
the synaptics driver, disabling tap to click while retaining the less
noisy Relative mode.

This patch adds support for two ALPS touchpad protocols not
supported currently by the driver, which I am arbitrarily naming
version 3 and version 4. Support is single-touch only at this time,
although both protocols are capable of limited multitouch support.

Thanks to Andrew Skalski, who did the initial reverse-engineering
of the v3 protocol.

Observing behavior of the other OS it appears that parity errors reported
by the keyboard controller are being ignored and the data is processed
as usual. Let's do the same for standard PS/2 protocols (bare, Intellimouse
and Intellimouse Explorer) to provide better compatibility. Thsi should fix

This adds support for OLPC's touchpad. It has lots of neat features,
none of which are enabled because the hardware is too buggy. Instead,
we use it like a normal touchpad, but with a number of workarounds in
place to deal with the frequent hardware spasms. Humidity changes,
sweat, tinfoil underwear, plugging in AC, drinks, evil felines.. All
tend to cause the touchpad to freak out.

us to set a 'protect' argument specifying whether or not the set

psmouse_queue_work is passed a delayed_work struct, and queues up the work

also switches resync_work to a delayed_work struct as well, and makes
use of psmouse_queue_work when doing a resync within psmouse-base.

7b595756ec1f49e0049a9e01a1298d53a7faaa15 13-Jun-2007 Tejun Heo <htejun@gmail.com> sysfs: kill unnecessary attribute->owner

sysfs is now completely out of driver/module lifetime game. After
deletion, a sysfs node doesn't access anything outside sysfs proper,
so there's no reason to hold onto the attribute owners. Note that
often the wrong modules were accounted for as owners leading to
accessing removed modules.

This patch kills now unnecessary attribute->owner. Note that with
this change, userland holding a sysfs node does not prevent the
backing module from being unloaded.

Cortron PS/2 Trackballs (700-0001A) report the 4th button using the 4th
bit of the first packet (yes, it breaks the standard PS/2 protocol).
This patch adds an extra protocol to generate BTN_SIDE based on the 4th
bit. There's no way to detect those trackballs using any kind of special
sequence, thus the protocol must be activated explicitely by writing
into 'protocol' sysfs attribute:

7d12e780e003f93433d49ce78cfedf4b4c52adc5 05-Oct-2006 David Howells <dhowells@redhat.com> IRQ: Maintain regs pointer globally rather than passing to IRQ handlers

Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.

The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around. On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).

Where appropriate, an arch may override the generic storage facility and do
something different with the variable. On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.

Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions. Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller. A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.

I've build this code with allyesconfig for x86_64 and i386. I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.

This will affect all archs. Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:

struct pt_regs *old_regs = set_irq_regs(regs);

And put the old one back at the end:

set_irq_regs(old_regs);

Don't pass regs through to generic_handle_irq() or __do_IRQ().

In timer_interrupt(), this sort of change will be necessary:

- update_process_times(user_mode(regs));
- profile_tick(CPU_PROFILING, regs);
+ update_process_times(user_mode(get_irq_regs()));
+ profile_tick(CPU_PROFILING);

I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().

Some notes on the interrupt handling in the drivers:

(*) input_dev() is now gone entirely. The regs pointer is no longer stored in
the input_dev struct.

(*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does
something different depending on whether it's been supplied with a regs
pointer or not.

(*) Various IRQ handler function pointers have been moved to type
irq_handler_t.
