Dmitry Torokhov ea486e6811 Input: serio - do not mark kseriod freezable anymore
We used to make kseriod freezable to prevent unnecessary attempts at
resuming keyboard and mouse before taking hibernation image when suspend
and hibernation were sharing PM operations. Now that they are separated
and we don't risk resuming during 'thaw' we don't need to freeze kseriod
anymore. This will allow us to start resetting mouse and keyboard a bit
earlier, before rest of the userspace comes back up.

We can't use msleep() while holding a spinlock, moreower serio's write()
method is supposed to be useable from inettrupt context. Let's do what
i8042 does and poll the status register every 50 us (with udelay).

Matthew Garrett 967c9ef9b8 Input: i8042 - allow installing platform filters for incoming data
Some hardware (such as Dell laptops) signal a variety of events through
the i8042 controller, even if these don't map to keyboard events. Add
support for drivers to filter the i8042 event stream in order to respond
to these events and (if appropriate) block them from entering the input
stream.

We need to protect not only i8042 status and data register from concurrent

and no support for docking station we can safely disable active MUX mode.

Dmitry Torokhov 181d683d75 Input: libps2 - additional locking for i8042 ports
The serio ports on i8042 are not completely isolated; while we provide
enough locking to ensure proper serialization when accessing control
and data registers AUX and KBD ports can still have an effect on each
other on PS/2 protocol level. The most prominent effect is that
issuing a command for the device connected to one port may cause
abort of the command currently executing by the device connected to
another port.

Since i8042 nor serio subsystem are not aware of the details of the
PS/2 protocol (length of the commands and their replies and so on) the
locking should be done on libps2 level by adding special handling when
we see that we are dealing with serio port on i8042.

Dmitry Torokhov 5ddbc77c3e Input: i8042 - try disabling and re-enabling AUX port at close
Ever since we switched from having a polling timer to registering IRQ
handlers for both keyboard and AUX ports at the driver registration
time, on certain boxes probing for a mouse results in keyboard
stopping working. The only real difference between old and new way is
that before we disabled ports after unsuccessful probe whereas now we
leave them as is. Try to emulate the old behavior by disabling and
immediately re-enabling AUX and KBD ports when corresponding serio
port is being closed.

Dmitry Torokhov 1c7827ae70 Input: i8042 - bypass AUX IRQ delivery test on laptops
It seems that many laptops do not fully implement AUX LOOP command in
their keyboard controllers, causing issues with touchpad detection.
We know however that almost every laptop/portable uses a PS/2 pointing
device and, even if user disables it in favor of an external mouse,
the system will not use IRQ 12 for anything else. Therefore we may
bypass AUX IRQ delivery test when running on a laptop and assume that
it is routed properly.

Just to be safe we require the box to have good PNP data in order to
bypass the test.
