54de247a0e dt-bindings: Updates Linus Walleij's mail address 
My name is stamped into maintainership for a big slew of DT
bindings. Now that it is changing, switch it over to my
kernel.org mail address, which will hopefully be stable for the
rest of my life.

cf6f234d7d dt-bindings: touchscreen: add debounce-delay-us property 
Add support for glitch delay configuration. A detected signal is valid
only if it remains stable longer than the configured delay; otherwise,
it is considered a glitch.

This property was introduced for the i.MX6UL touchscreen controller (TSC),
which provides a hardware deglitch filter with four thresholds depending
on the IPG clock frequency. In this use case, the IPG clock rate is 66 MHz,
resulting in thresholds of 124 µs, 62 µs, 31 µs, and 15 µs, which requires
a property with microsecond-level resolution.

f9d803784f dt-bindings: input: touchscreen: document Himax HX852x(ES) 
Himax HX852x(ES) is a touch panel controller with optional support
for capacitive touch keys.

Unfortunately, the model naming is quite unclear and confusing. There
seems to be a distinction between models (e.g. HX8526) and the "series"
suffix (e.g. -A, -B, -C, -D, -E, -ES). But this doesn't seem to be
applied very consistently because e.g. HX8527-E(44) actually seems to
belong to the -ES series.

The compatible consists of the actual part number followed by the
"series" as fallback compatible. Typically only the latter will be
interesting for drivers as there is no relevant difference on the
driver side.

88fb51ea6a dt-bindings: input: touchscreen: st1232: add touch-overlay example 
The touch-overlay feature adds support for segments (touch areas) on the
touchscreen surface that represent overlays with clipped touchscreen
areas and printed buttons.

Add nodes for a clipped touchscreen and overlay buttons to the existing
example.

19875ccec0 dt-bindings: touchscreen: add touch-overlay property 
The touch-overlay encompasses a number of touch areas that define a
clipped touchscreen area and/or buttons with a specific functionality.

A clipped touchscreen area avoids getting events from regions that are
physically hidden by overlay frames.

For touchscreens with printed overlay buttons, sub-nodes with a suitable
key code can be defined to report key events instead of the original
touch events.

c44f79cbd3 dt-bindings: HID: i2c-hid: elan: Introduce Elan eKTH8D18 
The Elan eKTH8D18 touchscreen controller is an I2C HID device with a
longer boot-up time. Power sequence timing wise it is compatible with
the eKTH6A12NAY, with a power-on delay of at least 5ms, 20ms
out-of-reset for I2C ack response, and 150ms out-of-reset for I2C HID
enumeration, both shorter than what the eKTH6A12NAY requires.
Enumeration and subsequent operation follows the I2C HID standard.

Add a compatible string for it with the ekth6a12nay one as a fallback.
No enum was used as it is rare to actually add new entries. These
chips are commonly completely backward compatible, and unless the
power sequencing delays change, there is no real effort being made to
keep track of new parts, which come out constantly.

Also drop the constraints on the I2C address since it's not really
part of the binding.

5d511d93c0 dt-bindings: input: touchscreen: edt-ft5x06: use unevaluatedProperties 
In Xiaomi Poco F1 (qcom/sdm845-xiaomi-beryllium-ebbg.dts), the FocalTech
FT8719 touchscreen is integrally connected to the display panel
(EBBG FT8719) and thus should be power sequenced together with display
panel using the panel property. Since the edt-ft5x06 touchscreen binding
uses almost all the properties present in touchscreen.yaml, let's remove
additionalProperties: false and use unevaluatedProperties to include all
the properties, including the needed panel property.
