Use the newly introduced devm_ioremap_resource() instead of
devm_request_and_ioremap() which provides more consistent error handling.
devm_ioremap_resource() provides its own error messages; so all explicit
error messages can be removed from the failure code paths.

Merge tag 'v3.9-rc3' into next
Merge with mainline to bring in module_platform_driver_probe() and
devm_ioremap_resource().
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.

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.

Add the necessary code to create the needed platformdata from devicetree
informations.
The interrupt mode of the chip is not set via devicetree, as it is not
a property of the hardware but instead only a preferred type of operation.
This should probably be made settable via configfs in the future.
The option set as default is the mode the datasheet mentions as default.

Devicetree based platforms don't handle device callbacks very well
and until now no board has come along that needs more extended hwinit
than pulling the rst gpio high.
Therefore pull the reset handling directly into the driver and remove
the callbacks from the driver.

would probably be the solution of choice.

These touchpads use a different protocol; they have been seen on Dell
N5110, Dell 17R SE, and others.
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
73 02 xx (02 has been seen).
Dolphin V2 probably needs a different initialization sequence and/or

Tegra only supports, and always enables, device tree. Remove all ifdefs
and runtime checks for DT support from the driver. Platform data is
therefore no longer required. Delete the header that defines it, and
rework the driver to parse the device tree directly into struct
tegra_kbc.

To properly setup event parameters for emulated events, pass
the appropriate flag to the slot initialization function. Also,
all MT-related events should be setup before initialization.
Incidentally, this solves the issue of doubly filtered pointer
events.

Make the constants referring to range and bandwidth public so they can
be used when initializing the platform data fields in the platform code.
Fix also some comments regarding the unit of measurement to use for the
range and bandwidth fields, the values are not actually expected to be
in G or HZ, the code in bma150.c just uses the BMA150_RANGE_xxx and
BMA150_BW_xxx constants like they are with no translation from actual
values in G or HZ.

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.
