ac2ee9ba95 Input: cm109 - validate number of endpoints before using them
Make sure to check the number of endpoints to avoid dereferencing a
NULL-pointer should a malicious device lack endpoints.

If user tries to initialize uinput device mixing old and new style
initialization (i.e. using old UI_SET_ABSBIT instead of UI_ABS_SETUP,
we forget to allocate input->absinfo and will crash when trying to send
absolute events:

        ioctl(ui, UI_DEV_SETUP, &us);

b1fe0cf06f Input: delete MPU3050 driver
The MPU3050 driver in the input subsystem has been superseded by a proper
IIO driver found in drivers/iio/gyro/mpu3050*.

Patches have been submitted to remove all defconfig and related references
to the old driver and replace this input driver with the IIO driver.

So delete the input driver. Input was never a good fit for sensors anyway.

This adds an optional regulator to the pwm-beeper device. This regulator
acts as an amplifier. The amplifier is only enabled while beeping in order
to reduce power consumption.

an amplifier.

e9728f0dd7 Input: pwm-beeper - fix race when suspending
Usually userspace sends SND_BELL and SND_TONE events, and by the time
pwm_beeper_suspend() runs userpsace is already frozen, but theoretically
in-kernel users may send these events too, and that may cause
pwm_beeper_event() scheduling another work after we canceled it.

Let's introduce a "suspended" flag and check it in pwm_beeper_event() to
avoid this race.

Similarly, disabling wakeup in the probe error path is unnecessary, as is
disabling wakeup in the probe function in the first place.

The soc_button_array driver was initializing (kzalloc) the
debounce_interval value to 0, leading to no debouncing at all,
while the buttons are simple mechanical switches.

This commit sets debounce_interval to 50ms to avoid spurious button
press reports both on press and release of the button. Note 50ms may
seem like a lot but soc_button_array is typically used with cheap
tablets, with not so great buttons. I tried 10ms on my tablet and it
is not enough, where as 50ms works well.

ce38207f16 sound updates for 4.10-rc1
No dramatic changes are found in this development cycle, but as usual,
 many commits are applied in a wide range of drivers.
 
 Most of big changes are in ASoC, where a few bits of framework work
 and quite a lot of cleanups and improvements to existing code have
 been done.  The rest are usual stuff, a few HD-audio and USB-audio
 quirks and fixes, as well as the drop of kthread usages in the whole
 subsystem.
 
 Below are some highlights:
 
 ASoC:
 - Support for stereo DAPM controls
 - Some initial work on the of-graph sound card
 - regmap conversions of the remaining AC'97 drivers
 - A new version of the topology ABI; this should be backward compatible

Merge tag 'sound-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "No dramatic changes are found in this development cycle, but as usual,
  many commits are applied in a wide range of drivers.

  Most of big changes are in ASoC, where a few bits of framework work
  and quite a lot of cleanups and improvements to existing code have
  been done. The rest are usual stuff, a few HD-audio and USB-audio
  quirks and fixes, as well as the drop of kthread usages in the whole
  subsystem.

  Below are some highlights:

  ASoC:
   - support for stereo DAPM controls
   - some initial work on the of-graph sound card
   - regmap conversions of the remaining AC'97 drivers
   - a new version of the topology ABI; this should be backward
     compatible
   - updates / cleanups of rsnd, sunxi, sti, nau8825, samsung, arizona,
     Intel skylake, atom-sst
   - new drivers for Cirrus Logic CS42L42, Qualcomm MSM8916-WCD, and

  USB-audio:
   - yet another race fix at disconnection

We were assigning I2C bus controller instead of client as parent device.
Besides being logically wrong, it messed up with devm handling of input
device. As a result we were leaving input device and event node behind
after rmmod-ing the driver, which lead to a kernel oops if one were to
access the event node later.

Let's remove the assignment and rely on devm_input_allocate_device() to
set it up properly for us.

The name of a codec pin can have an optional prefix string, which is
defined by the SoC machine driver. The snd_soc_dapm_x_pin functions
take the fully-specified name including the prefix and so the existing
code would fail to find the pin if the audio machine driver had added
a prefix.

Switch to using the snd_soc_component_x_pin equivalent functions that
take a specified SoC component and automatically add the name prefix to
the provided pin name.

6473bbfd7e Input: drv2667 - fix misuse of regmap_update_bits
Using regmap_update_bits(..., mask, 1) with 'mask' following (1 << k)
and k greater than 0 is wrong. Indeed, _regmap_update_bits will perform
(mask & 1), which results in 0 if LSB of mask is 0. Thus the call
regmap_update_bits(..., mask, 1) is in reality equivalent to
regmap_update_bits(..., mask, 0).

In such a case, the correct use is regmap_update_bits(..., mask, mask).

This driver is performing such a mistake with the DRV2667_STANDBY mask,
which equals (1 << 6). Fix the driver to make it consistent with the
API, and fix the alignment problem at the same time. Please note that
this change is untested, as I do not have this piece of hardware.

baf28d91e7 Input: bma150 - avoid binding to bma180 if IIO bma180 driver present
commit ef3714fdbc ("Input: bma150 - extend chip detection for bma180"),
adds bma180 chip-ids to the input bma150 driver, assuming that they are
100% compatible, but the bma180 is not compatible with the bma150 at all,
it has 14 bits resolution instead of 10, and it has quite different
control registers too.

Treating the bma180 as a bma150 wrt its data registers will just result
in throwing away the lowest 4 bits, which is not too bad. But the ctrl
registers are a different story. Things happen to just work but supporting
that certainly does not make treating the bma180 the same as the bma150
right.

Since some setups depend on the evdev interface the bma150 driver offers
on top of the bma180, we cannot simply remove the bma180 ids.

So this commit only removes the bma180 id when the bma180 iio driver,
which does treat the bma180 properly, is enabled.

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.

$ modinfo drivers/input/misc/da9063_onkey.ko | grep alias
alias:          platform:da9063-onkey

6946416164 Input: add generic input driver to read encoded GPIO lines
Add a driver to read group of GPIO lines and provide its status as a
numerical value as input event to the system. This will help in
interfacing devices, that can be connected over GPIOs, that provide
input to the system by driving GPIO lines connected to them like a
rotary dial or a switch.

For example, a rotary switch can be connected to four GPIO lines. The
status of the GPIO lines reflect the actual position of the rotary
switch dial. For example, if dial points to 9, then the four GPIO lines
connected to the switch will read HLLH(0b'1001 = 9). This value
can be reported as an ABS_* event to the input subsystem.
