Pull input layer fixes from Dmitry Torokhov:
"The changes are limited to adding new VID/PID combinations to drivers
to enable support for new versions of hardware, most notably hardware
found in new MacBook Pro Retina boxes."
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
Input: xpad - add Andamiro Pump It Up pad

I couldn't find the vendor ID in any of the online databases, but this

and a disclaimer stating that Andamiro will not be liable on the bottom.

Pull input layer fixes from Dmitry Torokhov:
"Two fixes for regressions in Wacom driver and fixes for drivers using
threaded IRQ framework without specifying IRQF_ONESHOT."
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
Input: request threaded-only IRQs with IRQF_ONESHOT
Input: wacom - don't retrieve touch_max when it is predefined
Input: wacom - fix retrieving touch_max bug
Input: fix input.h kernel-doc warning
|
|
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.

Since there are uses for I2C_M_NOSTART which are much more sensible and
standard than most of the protocol mangling functionality (the main one
being gather writes to devices where something like a register address
needs to be inserted before a block of data) create a new I2C_FUNC_NOSTART
for this feature and update all the users to use it.
Also strengthen the disrecommendation of the protocol mangling while we're
at it.
In the case of regmap-i2c we remove the requirement for mangling as
I2C_M_NOSTART is the only mangling feature which is being used.

Pull USB 3.5-rc1 changes from Greg Kroah-Hartman:
"Here is the big USB 3.5-rc1 pull request for the 3.5-rc1 merge window.
It's touches a lot of different parts of the kernel, all USB drivers,
due to some API cleanups (getting rid of the ancient err() macro) and
some changes that are needed for USB 3.0 power management updates.
There are also lots of new drivers, pimarily gadget, but others as
well. We deleted a staging driver, which was nice, and finally
dropped the obsolete usbfs code, which will make Al happy to never
have to touch that again.
There were some build errors in the tree that linux-next found a few
days ago, but those were fixed by the most recent changes (all were
due to us not building with CONFIG_PM disabled.)

The modern idiom is to use irq_domain to allocate interrupts. This is
useful partly to allow further infrastructure to be based on the domains
and partly because it makes it much easier to allocate virtual interrupts
to devices as we don't need to allocate a contiguous range of interrupt
numbers.
Convert the wm831x driver over to this infrastructure, using a legacy
IRQ mapping if an irq_base is specified in platform data and otherwise
using a linear mapping, always registering the interrupts even if they
won't ever be used. Only boards which need to use the GPIOs as
interrupts should need to use an irq_base.
This means that we can't use the MFD irq_base management since the
unless we're using an explicit irq_base from platform data we can't rely
on a linear mapping of interrupts. Instead we need to map things via
the irq_domain - provide a conveniencem function wm831x_irq() to save a
small amount of typing when doing so. Looking at this I couldn't clearly
see anything the MFD core could do to make this nicer.
Since we're not supporting device tree yet there's no meaningful
advantage if we don't do this conversion in one, the fact that the
interrupt resources are used for repeated IP blocks makes accessor
functions for the irq_domain more trouble to do than they're worth.

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.

atmel_mxt devices will send a checksum byte at the end of a message if
the MSB of the object address is set.
However, since this driver does not set this bit, the checksum byte
isn't actually sent, so don't even try to read it.
