As talked about in the patch ("drm/panel: Add a way for other devices
to follow panel state"), touchscreens that are connected to panels are
generally expected to be power sequenced together with the panel
they're attached to. Today, nothing provides information allowing you
to find out that a touchscreen is connected to a panel. Let's add a
phandle for this.
The proerty is added to the generic touchscreen bindings and then
enabled in the bindings for the i2c-hid backed devices. This can and
should be added for other touchscreens in the future, but for now
let's start small.

Sync up with mainline to bring in the latest API changes.
This converts the Zinitix BT4xx and BT5xx touchscreen bindings to YAML,
fix them up a bit and extends them.
We list all the existing BT4xx and BT5xx components with compatible
strings. These are all similar, use the same bindings and work in
similar ways.
We rename the supplies from the erroneous vdd/vddo to the actual supply
names vcca/vdd as specified on the actual component. It is long
established that supplies shall be named after the supply pin names of a
component. The confusion probably stems from that in a certain product
the rails to the component were named vdd/vddo. Drop some notes on how OS
implementations should avoid confusion by first looking for vddo, and if
that exists assume the legacy binding pair and otherwise use vcca/vdd.
Add reset-gpios as sometimes manufacturers pulls a GPIO line to the reset
line on the chip.
Add optional touchscreen-fuzz-x and touchscreen-fuzz-y properties.

After introducing a proper description of the MFD, this is the second

At the moment, the edt-ft5x06 driver can control a single regulator
("vcc"). However, some FocalTech touch controllers have an additional
IOVCC pin that should be supplied with the digital I/O voltage.
The I/O voltage might be provided by another regulator that should also
be kept on. Otherwise, the touchscreen can randomly stop functioning if
the regulator is turned off because no other components still require it.
Document (optional) support for controlling the regulator for IOVCC
using "iovcc-supply".

This converts the CYTTSP "Cypress TrueTouch Standard Product"
to YAML bindings and fixes and adds some things in the process:
- Rename the bindings file to cypress,cy8ctma340 after the main
product in the series.
- Add proper compatibles for the two known products:
CY8CTMA340 and CY8CTST341.
- Deprecate "cypress,cyttsp-spi" and "cypress,cyttsp-i2c"
because device compatibles should be named after the
hardware and not after which bus they are connected to.
The topology implicitly tells us which bus it is and what
interface to used.
- Add VCPIN and VDD supplies, these are present just like
on the CY8CTMA140.

DT properties which can have multiple entries need to specify what the
entries are and define how many entries there can be. In the case of
only a single entry, just 'maxItems: 1' is sufficient.
Add the missing entry constraints. These were found with a modified
meta-schema. Unfortunately, there are a few cases where the size
constraints are not defined such as common bindings, so the meta-schema
can't be part of the normal checks.

json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.
This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.
Scripted with ruamel.yaml with some manual fixups. Some minor whitespace
changes from the script.

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.

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.
