commit 32ed1911fc upstream.
The tsc40 driver announces it supports the pressure event, but will never
send one. The announcement will cause tslib to wait for such events and
sending all touch events with a pressure of 0. Removing the announcement
will make tslib fall back to emulating the pressure on touch events so
everything works as expected.

commit 6dc463511d upstream.
Bamboo One's with ID of 0x6a and 0x6b were added with correct
indication of 1024 pressure levels but the Graphire packet routine
was only looking at 9 bits. Increased to 10 bits.
This bug caused these devices to roll over to zero pressure at half
way mark.
The other devices using this routine only support 256 or 512 range
and look to fix unused bits at zero.

commit 4eef6cbfcc upstream.
The EETI touchscreen asserts its IRQ line as soon as it has data in its
internal buffers. The line is automatically deasserted once all data has
been read via I2C. Hence, the driver has to monitor the GPIO line and
cannot simply rely on the interrupt handler reception.
In the current implementation of the driver, irq_to_gpio() is used to
determine the GPIO number from the i2c_client's IRQ value.
As irq_to_gpio() is not available on all platforms, this patch changes
this and makes the driver ignore the passed in IRQ. Instead, a GPIO is
added to the platform_data struct and gpio_to_irq is used to derive the
IRQ from that GPIO. If this fails, bail out. The driver is only able to
work in environments where the touchscreen GPIO can be mapped to an
IRQ.
Without this patch, building raumfeld_defconfig results in:
drivers/input/touchscreen/eeti_ts.c: In function 'eeti_ts_irq_active':
drivers/input/touchscreen/eeti_ts.c:65:2: error: implicit declaration of function 'irq_to_gpio' [-Werror=implicit-function-declaration]

Pull "Disintegrate and delete asm/system.h" from David Howells:
"Here are a bunch of patches to disintegrate asm/system.h into a set of
separate bits to relieve the problem of circular inclusion
dependencies.
I've built all the working defconfigs from all the arches that I can
and made sure that they don't break.
The reason for these patches is that I recently encountered a circular
dependency problem that came about when I produced some patches to
optimise get_order() by rewriting it to use ilog2().
This uses bitops - and on the SH arch asm/bitops.h drags in
asm-generic/get_order.h by a circuituous route involving asm/system.h.
The main difficulty seems to be asm/system.h. It holds a number of
low level bits with no/few dependencies that are commonly used (eg.
memory barriers) and a number of bits with more dependencies that
aren't used in many places (eg. switch_to()).
These patches break asm/system.h up into the following core pieces:
(1) asm/barrier.h
Move memory barriers here. This already done for MIPS and Alpha.
(2) asm/switch_to.h
Move switch_to() and related stuff here.
(3) asm/exec.h
Move arch_align_stack() here. Other process execution related bits
could perhaps go here from asm/processor.h.
(4) asm/cmpxchg.h
Move xchg() and cmpxchg() here as they're full word atomic ops and
frequently used by atomic_xchg() and atomic_cmpxchg().
(5) asm/bug.h
Move die() and related bits.
(6) asm/auxvec.h
Move AT_VECTOR_SIZE_ARCH here.
Other arch headers are created as needed on a per-arch basis."
Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that. We'll find out anything that got broken and fix it..

The 3rd gen Bamboo Pen & Touch and Intuos5 tablets support an
optional wireless module. When its receiver is plugged into USB,
it presents 3 interfaces: 0) Monitor 1) Pen and 2) Touch.
The exact capabilities of the Pen and Touch interfaces can
not be determined until a tablet connection is established
and reported over the Monitor interface.
This patch detects this wireless receiver and enables interrupt
packets to be processed for the Monitor interface. Processing
the data in packets will be left to another patch.
Since it doesn't make sense to create an input device for the
Monitor interface, it is not created. Creation of Pen and Touch
input device is also delayed until monitor packets can be processed.

- Hooking multi-finger coordinates output with kernel multitouch library;
- Enabling absolute coordinates output for Cx+ hardware. The older hardware
performs much better in relative mode; thus relative mode related code
are preserved.
Part of the code is based on the work done by Oskari Saarenmaa <os@ohmu.fi>,
which was used to support the clickpad found on ASUS UX21/31 Ultrabook.
On the other hand, the FSP found on UX21/31 doesn't have hardware capability
register other than PnP ID, which means that we'll have to figure out an
alternative approach to identify such pad correctly; otherwise, blindly
adding INPUT_PROP_BUTTONPAD property may compatability issues amongst
existing FSPs.

- Move event bits setup code into a separate function,
fsp_set_input_params(), so that we can perform hardware-specific settings
in the future;
- Take hardware version information into account when activating
protocol;
- Remove button information from boot message as it's somewhat confusing
and is only for internal processing. While there, also move button
retrieval code to be a part of protocol activation process.
