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.
