This patch removes common ADC settings in favor to use
stmpe811_adc_common_init that is present in MFD. This is necessary in
preparation for the stmpe-adc driver, because those two drivers have
common settings for the ADC.

[ Upstream commit 463fa44eec2fef50d111ed0199cf593235065c04 ]
Across suspend and resume, we are seeing error messages like the following:
atmel_mxt_ts i2c-PRP0001:00: __mxt_read_reg: i2c transfer failed (-121)
atmel_mxt_ts i2c-PRP0001:00: Failed to read T44 and T5 (-121)
This occurs because the driver leaves its IRQ enabled. Upon resume, there
is an IRQ pending, but the interrupt is serviced before both the driver and
the underlying I2C bus have been resumed. This causes EREMOTEIO errors.
Disable the IRQ in suspend, and re-enable it on resume. If there are cases
where the driver enters suspend with interrupts disabled, that's a bug we
should fix separately.

The device md->input is used after it is released. Setting the device
data to NULL is unnecessary as the device is never used again. Instead,
md->input should be assigned NULL to avoid accessing the freed memory
accidently. Besides, checking md->si against NULL is superfluous as it
points to a variable address, which cannot be NULL.

The current reset-gpio support triggers an interrupt storm on platforms
using the maxtouch with level based interrupt. The Motorola Droid 4,
which I used for some of the tests is not affected, since it uses a edge
based interrupt.
This change avoids the interrupt storm by enabling the device while its
interrupt is disabled. Afterwards we wait 100ms. This is important for
two reasons: The device is unresponsive for some time (~22ms for
mxt224E) and the CHG (interrupt) line is not working properly for 100ms.
We don't need to wait for any following interrupts, since the following
mxt_initialize() checks for bootloader mode anyways.
This fixes a boot issue on GE PPD (watchdog kills device due to
interrupt storm) and does not cause regression on Motorola Droid 4.

According to multi-touch-protocol.txt the kernel knows two type of
devices:
- Type A: devices which provide anonymous contacts
- Type B: devices which are capable of tracking individual contacts
The Fusion touch screen is a Type B device: The Touch ID field allows
to differentiate between 2 different fingers. This updates the driver
to properly allocate a slot for each identified contact and use the
helper functions available from the input core system.

[ Upstream commit 36f5d9ef26e52edff046b4b097855db89bf0cd4a ]
The driver only registers one input device, which uses the screen
parameters from the first T9 instance. The first T63 instance also uses
those parameters.
It is incorrect to send input reports from the second instances of these
objects if they are enabled: the input scaling will be wrong and the
positions will be mashed together.
This also causes problems on Android if the number of slots exceeds 32.
In the future, this could be handled by looking for enabled touch object
instances and creating an input device for each one.

The touchscreen driver, max11801, which is on 12c2 bus, won't be probed
when using the hdcp specific DTS (this is disabling 12c2, since it
will acquire it for DDC communications). Since this driver won't be
probed, it will spam the dmesg with the pr_err from max11801_read_adc()
function. This function is periodically called by the battery driver. For
this reason, I removed the pr_err() call.
Also, to be noticed that the function signature is u32, but in case of an
error it will return a negative integer. In order to correctly propagate
errors, I changed the function signature to int. This is safe, since the
read value from i2c is on 16 bits (MSB and LSB on 8 bits).
Also, the function calibration_voltage is calling max11801_read_adc from
touchscreen driverm which can return negative values in case of an
error. I case of an error, just stop reading ADC data and return 0 as
voltage_data.

cherry-pick below patch:
ENGR00275004-1 input: touchscreen: max11801_ts: Add DCM mode for max11801 ADC
We need add DCM mode/AUX mode for ADC converter function of max11801, so that
it can be used to read voltage of battery. Meanwhile, let the driver based on
device tree. The patchset is based on below patch (V3.5.7):

commit f372b81101e6895252298e563d634d5e44ae81e7 upstream.
This patch adds the correct platform data information for the Caroline
Chromebook, so that the mouse button does not get stuck in pressed state
after the first click.
The Samus button keymap and platform data definition are the correct
ones for Caroline, so they have been reused here.

[ Upstream commit faec44b6838312484d63e82286087cf2d5ebb891 ]
We should not try to do any i2c transfers before the controller is
resumed (which happens before our resume method gets called).
So we need to disable our IRQ while suspended to enforce this. The
code paths for devices with GPIOs for the int and reset pins already
disable the IRQ the through goodix_free_irq().
This commit also disables the IRQ while suspended for devices without
GPIOs for the int and reset pins.
This fixes the i2c bus sometimes getting stuck after a suspend/resume
causing the touchscreen to sometimes not work after a suspend/resume.
This has been tested on a GPD pocked device.
