The trackpoint driver sets various parameter default values, all of

Specification, Version 4.0. Also confirmed by empirical data).
By sending the power-on reset command to reset all parameters to
power-on state, we can skip the lengthy process of programming all

to .35 seconds waiting for power-on reset to complete.

We now have a binding which adds two parameters to the matrix keypad DT
node. This is separate from the GPIO-driven matrix keypad binding, and
unfortunately incompatible, since that uses row-gpios/col-gpios for the
row and column counts.
So the easiest option here is to provide a function for non-GPIO drivers
to use to decode the binding.
Note: We could in fact create an entirely separate structure to hold
these two fields, but it does not seem worth it, yet. If we have more
parameters then we can add this, and then refactor each driver to hold
such a structure.

Things are calming down for arm-soc as well. This set of bug fixes is
dominated in size by the at91 platform bug fixes. Some of them were
meant to go through the framebuffer tree during the merge window, but
since the framebuffer maintainer could not be reached, I offered to
take them here. The other notable at91 change is the addition of pinctrl
definitions to fix the NAND controller.
The rest are mostly simple regression fixes:
* Our removal of VIRT_TO_BUS conflicted with Stephen Rothwell's
renaming of the Kconfig symbol. You will get a trivial merge conflict
here, we still want to remove it.
* missing bits for clocks on imx and s5pv210
* missing header inclusions in mmp and shmobile
* typos in s5pv210 camera and vt8500 clock support code
and three trivial fixes for pre-3.8 bugs:
* an old bogus build warning in the joystick driver
* a misleading Kconfig description
* a NULL pointer check on davinci

Merge tag 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC bug fixes from Arnd Bergmann:
"Things are calming down for arm-soc as well. This set of bug fixes is
dominated in size by the at91 platform bug fixes. Some of them were
meant to go through the framebuffer tree during the merge window, but
since the framebuffer maintainer could not be reached, I offered to
take them here. The other notable at91 change is the addition of
pinctrl definitions to fix the NAND controller.
The rest are mostly simple regression fixes:
- Our removal of VIRT_TO_BUS conflicted with Stephen Rothwell's
renaming of the Kconfig symbol. You will get a trivial merge
conflict here, we still want to remove it.
- missing bits for clocks on imx and s5pv210
- missing header inclusions in mmp and shmobile
- typos in s5pv210 camera and vt8500 clock support code
and three trivial fixes for pre-3.8 bugs:
- an old bogus build warning in the joystick driver
- a misleading Kconfig description
- a NULL pointer check on davinci"

ARM normally has an accurate clock source, so
we can theoretically use analog joysticks more
accurately and at the same time avoid the
build warning
#warning Precise timer not defined for this architecture.
from the joystick driver.
Now, why anybody would use that driver no ARM I have no
idea, but Ben Dooks enabled it in the s3c2410_defconfig
along with a bunch of other drivers, even though that
platform has neither ISA nor PCI support. It still
seems to be the right thing to fix this quirk.

The PCU is a device installed in the armrest of a plane seat and
is connected to IMS Rave Entertainment System. It has a set of control
buttons (Volume Up/Down, Attendant, Lights, etc) on one side and
gamepad-like controls on the other side.
Originally the device was handled from userspace and because of that
it presents itself on USB bus as a CDC-ACM modem device that however
can not make calls. However the custom handling is not as convenient
as using standard input subsystem facilities. If it was pure input
device it would be possible to continue using userspace solution
(moving it over to uinput), but the device also has backlighted keys
which can not be supported via uinput.

With fast movements, there occured some out of screen jumps with my
touchscreen. The abs_x and abs_y module parameters should fix this by
default, but the driver doesn't actively checks the x/y coordinates.
Instead it seems that the input layer was supposed to drop out of range
inputs, as described in the comments:
"These parameters are used to help the input layer discard out of
range readings and reduce jitter etc"
The input layer documentation describes that values that are not in the
absolute range are also accepted.
So this patch adds a check within the driver.

"Except for the largish change to the ALPS driver adding "Dolphin V1"

rest are straightforward driver fixes."

When it uses regulators the mms114 driver checks to see if it managed to
acquire regulators and ignores errors. This is not the intended usage and
not great style in general.
Since the driver already refuses to probe if it fails to allocate the
regulators simply make the enable and disable calls unconditional and
add appropriate error handling, including adding cleanup of the
regulators if setup_reg() fails.

There is a more complete atmel patch-series out by Nick Dyer that fixes
this and other things, but in the meantime this is the minimal thing to
get the touchscreen going on (at least my) Pixel Chromebook.
Not that I want my dirty fingers near that beautiful screen, but it
seems that a non-initialized touchscreen will also end up being a
constant wakeup source, so you have to disable it to go to sleep. And
it's easier to just fix the initialization sequence.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
This same driver can be used by atmel based touchscreens and touchpads
(buttonpads). Platform data may specify a device is a touchpad
using the is_tp flag.
This will cause the driver to perform some touchpad specific
initializations, such as:
* register input device name "Atmel maXTouch Touchpad" instead of
Touchscreen.
* register BTN_LEFT & BTN_TOOL_* event types.
* register axis resolution (as a fixed constant, for now)
* register BUTTONPAD property
* process GPIO buttons using reportid T19
Input event GPIO mapping is done by the platform data key_map array.
key_map[x] should contain the KEY or BTN code to send when processing
GPIOx from T19. To specify a GPIO as not an input source, populate
with KEY_RESERVED, or 0.

The interrupt mode of the chip is not set via devicetree, as it is not

These touchpads use a different protocol; they have been seen on Dell

The official ALPS driver identifies them by looking for an exact match
on the E7 report: 73 03 50. Dolphin V1 returns an EC report of
73 01 xx (02 and 0d have been seen); Dolphin V2 returns an EC report of

When PM_RUNTIME is not defined, pm_runtime_get_sync() returns 1, see
include/linux/pm_runtime.c::__pm_runtime_resume(), and the check of the
return value was overlooking this, in this case bma150_open() would
return 1 which is not expected by upper layers.
Maybe the check for != -ENOSYS (Function not implemented) was meant to
cover this, but pm_runtime_get_sync() does not return this value.
For now fix the issue locally by checking explicitly for negative return
values.

contacts are present:
Action SGM AGM (MTB slot:Contact)
1. Touch contact 0 (0:0)
2. Touch contact 1 (0:0, 1:1)
3. Lift contact 0 (1:1)
4. Touch contacts 2,3 (0:2, 1:3)
In step 4, slot 1 was not being cleared first, which means the same
tracking ID was being used for reporting both the old contact 1 and the
new contact 3. This could result in "drumroll", where the old contact 1
would appear to suddenly jump to new finger 3 position.
Similarly, if contacts 2 & 3 are not detected at the same sample, step 4
is split into two:
Action SGM AGM (MTB slot:contact)
1. Touch contact 0 (0:0)
2. Touch contact 1 (0:0, 1:1)
3. Lift contact 0 (1:1)
4. Touch contact 2 (0:2, 1:1)
5. Touch contact 3 (0:2, 1:3)
In this case, there was also a bug. In step 4, when contact 1 moves from
SGM to AGM and contact 2 is first reported in SGM, slot 0 was actually
empty. So slot 0 can be used to report the new SGM (contact 0),
immediately. Since it was empty, contact 2 in slot 0 will get a new
tracking ID.

When removing the !S390 dependency from drivers/input/Kconfig
a couple of drivers don't compile because they have a dependency
on GENERIC_HARDIRQS. So add the missing dependencies.
Fixes e.g. this one:

This patch replaces the horribly coded of_count_named_gpios() with a
call to of_count_phandle_with_args() which is far more efficient. This
also changes the return value of of_gpio_count() & of_gpio_named_count()
from 'unsigned int' to 'int' so that it can return an error code. All
the users of that function are fixed up to correctly handle a negative
return value.

Logic sets a value and then reads it back to make sure it worked
and retries write on failures. Since read and write share a buffer,
it needs to be set back up before writing though.
Issue is not seen a lot because 1) it doesn't need to retry for
a lot of tablets and 2) a lot of failures that need a retry are
from an -ETIMEDOUT and hopefully buffer is not touched in this case.
At least one user has shown logs with buffer being modified during
-ETIMEDOUT case with linux 3.7 kernel.

On resume from suspend there is a possibility for multi-byte scancodes
to be handled incorrectly. atkbd_reconnect disables the processing of
scancodes in software by calling atkbd_disable, but the keyboard may
still be active because no disconnect command was sent. Later, software
handling is re-enabled. If a multi-byte scancode sent from the keyboard
straddles the re-enable, only the latter byte(s) will be handled.
In practice, this leads to cases where multi-byte break codes (ex. "e0
4d" - break code for right-arrow) are misread as make codes ("4d" - make
code for numeric 6), leading to one or more unwanted, untyped characters
being interpreted.
The solution implemented here involves sending command f5 (reset
disable) to the keyboard prior to disabling software handling of codes.
Later, the command to re-enable the keyboard is sent only after we are
prepared to handle scancodes.

The option allows you to remove TTY and compile without errors. This
saves space on systems that won't support TTY interfaces anyway.
bloat-o-meter output is below.
The bulk of this patch consists of Kconfig changes adding "depends on
TTY" to various serial devices and similar drivers that require the TTY
layer. Ideally, these dependencies would occur on a common intermediate
symbol such as SERIO, but most drivers "select SERIO" rather than
"depends on SERIO", and "select" does not respect dependencies.
bloat-o-meter output comparing our previous minimal to new minimal by
removing TTY. The list is filtered to not show removed entries with awk
'$3 != "-"' as the list was very long.
