Input: bu21013_ts - switch to using standard touchscreen properties

2019-09-02T16:07:38+00:00

This switches the driver over to the standard touchscreen properties for
coordinate transformation, while keeping old bindings working as well.

Input: bu21013_ts - use interrupt from I2C client

2019-09-02T16:07:18+00:00

Instead of trying to map INT GPIO to interrupt, let's use one supplied by
I2C client. If there is none - bail. This will also allow us to treat INT
GPIO as optional, as per the binding.

Input: bu21013_ts - convert to use GPIO descriptors

2019-09-02T16:06:52+00:00

This driver can use GPIO descriptors rather than GPIO numbers
without any problems, convert it. Name the field variables after
the actual pins on the chip rather than the "reset" and "touch"
names from the devicetree bindings that are vaguely inaccurate.

No in-tree users pass GPIO numbers in platform data so drop
this. Descriptor tables can be used to get these GPIOs from a board
file if need be.

Input: ads7846 - add support for general touchscreen bindings

2019-08-09T14:44:11+00:00

A few vendor specific bindings are now covered by common bindings.

Let the driver parse the common bindings to make use of common
inverting and swapping mechnism. Aslo make use of
touchscreen_report_pos() to ensure the correct inverting-swapping
order.

The vendor specific properties are used as default (backward
compatibility) and gets overwritten by common bindings.

Merge tag 'v5.1' into next

Sync up with mainline to bring in the latest APIs.

Input: add support for Azoteq IQS550/572/525

2019-04-30T07:38:51+00:00

This patch adds support for the Azoteq IQS550/572/525 family of
trackpad/touchscreen controllers.

The driver has been tested with an IQS550EV02 evaluation board. A
demonstration of the driver's capabilities is available here:

Input: goodix - add GT5663 CTP support

2019-04-03T23:10:43+00:00

GT5663 is capacitive touch controller with customized smart
wakeup gestures.

Add support for it by adding compatible and supported chip data.

The chip data on GT5663 is similar to GT1151, like
- config data register has 0x8050 address
- config data register max len is 240
- config data checksum has 16-bit

Input: goodix - add regulators suppot

2019-04-03T23:10:42+00:00

Goodix CTP controllers require AVDD28, VDDIO regulators for power-on
sequence.

The delay between these regualtor operations as per Power-on Timing
from datasheet[1] is 0 (T1 >= 0 usec).

So, enable and disable these regulators in proper order using normal
regulator functions without any delay in between.
