9712fe00a7 Input: pm8941-pwrkey - disable wakeup for resin by default 
'Resin' (*Res*et *In*put) is usually connected to a volume down button
on devices, which is usually not expected to wake up the device from
suspend.

On the other hand, pwrkey should keep wakeup on. So do not enable wakeup
for resin unless the "wakeup-source" property is specified in
devicetree.

Note, that this does change behavior by turning off wakeup by default
for 'resin' and requiring a new dt property to be added to turn it on
again. But since this is not expected behavior in the first place, and
most users will not expect this, I'd argue this change is acceptable.

95e6b0af80 dt-bindings: input: pm8941-pwrkey: Document wakeup-source property 
The 'resin' keys (usually connected to a volume-down button) are
generally not supposed to wake up the device from suspend, so explicitly
document a wakeup-source property to enable this wakeup behavior.

For 'pwrkey' the default stays that pressing the button does wake up the
device from suspend.

c87a819bec Input: add driver for Hynitron CST816x series 
Introduce support for the Hynitron CST816x series touchscreen controller
used for 240×240 1.28-inch Round LCD Display Module manufactured
by Waveshare Electronics. The driver is designed based on an Arduino
implementation marked as under MIT License. This driver is written
for a particular round display based on the CST816S controller, which
is not compatiable with existing driver for Hynitron controllers.

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.

The driver is somewhat based on sample code from Himax. However, that
code was rather confusing, so that we spent a significant amount of
time just trying to understand the packet format and register commands.
In this driver they are described with clean structs and defines rather
than magic numbers and offset calculations.

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.

The binding currently expects exactly 5 keycodes, which matches the
chip's theoretical maximum but probably not the number of touch keys on
any phone using the IST3032C. Add a minItems value of 2 to prevent

Also add another example to make sure the linux,keycodes property is

9a12e2fb3f Input: tsc2007 - prevent overflow in pressure calculation 
The touch resistance calculation in the tsc2007 driver is prone to
overflow if (z2 - z1) is large and also x is reasonably big. This
overflow results in the driver emitting input events when very little
touch pressure is applied. In these events the x and y coordinates can
be substantially off.

Avoid the overflow by using u64 when calculating resistance value.

2215a87b02 mfd: tps6594: Add board power-off support 
Add a system level power-off handler if the "system-power-controller"
flag is set for this device in the device tree.

A power-off request is triggered by writing the TRIGGER_I2C_0 bit (which
is actually just a convention and really depends on the freely
programmable FSM).
