In the hopes that people run new kernels on their devices, let's add a
warning message asking users to have their DTS file fixed.
The goal is that by Linux 4.0 we will be able to remove support for the
bogus version of our touchscreen's DTS.

Rather than msleep for MXT_RESET_TIME and MXT_FWRESET_TIME during the
transition to bootloader mode and the transition back from app, wait for
the CHG assert to indicate that the transition is done.
This change replaces the msleep with a wait for completion that the
mxt_interrupt handler signals.
Also add CHG poll after last firmware frame - some bootloader versions will
assert the interrupt line after the final frame, in testing this meant that
the driver attempts to read the info block too early whilst the chip is
still resetting.
This improves firmware update time as we no longer wait longer than
necessary for each reset.

different maXTouch chips. Some have up to 7 GPIOs. Allowing a keycode array

It is not necessary to download these values to the maXTouch chip on every
probe, since they are stored in NVRAM. It makes life difficult when tuning
the device to keep them in sync with the config array/file, and requires a
new kernel build for minor tweaks.
These parameters only represent a tiny subset of the available
configuration options, tracking all of these options in platform data would
be a endless task. In addition, different versions of maXTouch chips may
have these values in different places or may not even have them at all.
Having these values also makes life more complex for device tree and other
platforms where having to define a static configuration isn't helpful.

Note the sun4i-ts controller is capable of detecting a second touch, but
when a second touch is present then the accuracy becomes so bad the
reported touch location is not useable.
The original android driver contains some complicated heuristics using the
aprox. distance between the 2 touches to see if the user is making a pinch
open / close movement, and then reports emulated multi-touch events around
the last touch coordinate (as the dual-touch coordinates are worthless).
These kinds of heuristics are just asking for trouble (and don't belong in
the kernel). So this driver offers straight forward, reliable single touch
functionality only.

While searching for users of spi_async() I found a reference in the ad7877
driver to using it to initiate data transfer from the interrupt handler.
However there is no code for this, instead the interrupt handler is a
threaded handler and uses spi_sync() instead.
Remove the bitrotted comment, though in actual fact the use case mentioned
is a great use for spi_async() since it would cut down on latency handling
the interrupt by saving us a context switch before we start SPI.
This was previously implemented, it was removed in commit b534422b2d

The function zforce_read_packet() reads 2 values (bytes) of payload
header, validates them and then proceeds to read the payload body.
The function stores all these in a u8 buffer.
The PAYLOAD_LENGTH check seems to be trying to detect an overflow error.

The purpose of reg_se_cache has been defeated. It should avoid the
read-back of the register to avoid the latency and the fact that the
bits are reset to 0 after the individual conversation took place.
The reason why this is required like this to work, is that read-back of
the register removes the bits of the ADC so they do not start another
conversation after the register is re-written from the TSC side for the
update.
To avoid the not required read-back I introduce a "set once" variant which
does not update the cache mask. After the conversation completes, the
bit is removed from the SE register anyway and we don't plan a new
conversation "any time soon". The current set function is renamed to
set_cache to distinguish the two operations.
This is a small preparation for a larger sync-rework.

handle_level_irq masks the interrupt before handling it, and only
unmasks it after the handler is finished. So when a touch event
happens after threads are suspended, but before the system is fully asleep
the irq handler tries to wakeup the thread which will only happen on the
next resume, resulting in the wakeup event never being sent and the driver
not being able to wake the system from sleep due to the masked irq.
Therefore move the wakeup_event to a small non-threaded handler.

This patch supports the separate handling of the USB transfer buffer length
and the length of the buffer used for multi packet support. For devices
supporting multiple report or diagnostic packets, the USB transfer size is now
limited to the USB endpoints wMaxPacketSize - otherwise it defaults to the
configured report packet size as before.
This fixes an issue where event reporting can be delayed for an arbitrary
time for multi packet devices. For instance the report size for eGalax devices
is defined to the 16 byte maximum diagnostic packet size as opposed to the 5
byte report packet size. In case the driver requests 16 byte from the USB
interrupt endpoint, the USB host controller driver needs to split up the
request into 2 accesses according to the endpoints wMaxPacketSize of 8 byte.
When the first transfer is answered by the eGalax device with not less than
the full 8 byte requested, the host controller has got no way of knowing
whether the touch controller has got additional data queued and will issue
the second transfer. If per example a liftoff event finishes at such a
wMaxPacketSize boundary, the data will not be available to the usbtouch driver
until a further event is triggered and transfered to the host. From user
perspective the BTN_TOUCH release event in this case is stuck until the next
touch down event.

A number of new drivers and some new functionality + a lot of cleanups
all over IIO.
New Core Elements
1) New INT_TIME info_mask element for integration time, which may have
different effects on measurement noise and similar, than an amplifier
and hence is different from existing SCALE. Already existed in some
drivers as a custom attribute.
2) Introduce a iio_push_buffers_with_timestamp helper to cover the common
case of filling the last 64 bits of data to be passed to the buffer with
a timestamp. Applied to lots of drivers. Cuts down on repeated code and
moves a slightly fiddly bit of logic into a single location.
3) Introduce info_mask_[shared_by_dir/shared_by_all] elements to allow support

Jonathan writes:
First round of new drivers, functionality and cleanups for IIO in the 3.13 cycle
A number of new drivers and some new functionality + a lot of cleanups
all over IIO.
New Core Elements
1) New INT_TIME info_mask element for integration time, which may have
different effects on measurement noise and similar, than an amplifier
and hence is different from existing SCALE. Already existed in some
drivers as a custom attribute.
2) Introduce a iio_push_buffers_with_timestamp helper to cover the common
case of filling the last 64 bits of data to be passed to the buffer with
a timestamp. Applied to lots of drivers. Cuts down on repeated code and
moves a slightly fiddly bit of logic into a single location.
3) Introduce info_mask_[shared_by_dir/shared_by_all] elements to allow support
of elements such as sampling_frequency which is typically shared by all
input channels on a device. This reduces code and makes these controls
available from in kernel consumers of IIO devices.
New drivers
1) MCP3422/3/4 ADC
2) TSL4531 ambient light sensor

Enable shared IRQ to allow ADC to share IRQ line from
parent MFD core. Only FIFO0 IRQs are for TSC and handled
on the TSC side.
Step mask would be updated from cached variable only previously.
In rare cases when both TSC and ADC are used, the cached
variable gets mixed up.
The step mask is written with the required mask every time.
Rachna Patil (TI) laid ground work for shared IRQ.

The previous patch ("input/ti_am335x_tsc: ACK the HW_PEN irq in ISR")
acked the interrupt so we don't freeze if we don't handle an enabled
interrupt source. The interrupt core has a mechanism for this and to get
it work one should only say that it handled an interrupt if it is
actually the case.

The interrupt source IRQENB_HW_PEN is enabled in suspend and suposed to
be used as a wake up source. Once this interrupt source is unmaksed, the
devices ends up in ISR and never continues.
This change ACKs the interrupt and disables it so the system does not
freeze.
Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
The driver programs a threshold of "coordinate_readouts" say 5. The
REG_FIFO0THR registers says it should it be programmed to "threshold
minus one". The driver does not expect just 5 coordinates but 5 * 2 + 2.
Multiplied by two because 5 for X and 5 for Y and plus 2 because we have
two Z.
The whole thing kind of works because It reads the 5 coordinates for X
and Y from FIFO0 and FIFO1 and the last element in each FIFO is ignored
within the loop and read later.
Nothing guaranties that FIFO1 is ready by the time it is read. In fact I
could see that that FIFO1 reaturns for Y channels 8,9, 10, 12, 6 and for
Y channel 7 for Z. The problem is that channel 7 and channel 12 got
somehow mixed up.
The other Problem is that FIFO1 is also used by the IIO part leading to
wrong results if both (tsc & adc) are used.
The patch tries to clean up the whole thing a little:
- Remove the +1 and -1 in REG_STEPCONFIG, REG_STEPDELAY and its counter
part in the for loop. This is just confusing.
- Use only FIFO0 in TSC. The fifo has space for 64 entries so should be
fine.
- Read the whole FIFO in one function and check the channel.
- in case we dawdle around, make sure we only read a multiple of our
