Dmitry Torokhov 4c83c071b7 Input: elants_i2c - do not clobber interrupt trigger on x86 
This is similar to commit a4b0a58bb1 ("Input: elan_i2c - do not
clobber interrupt trigger on x86")

On x86 we historically used falling edge interrupts in the driver
because that's how first Chrome devices were configured. They also
did not use ACPI to enumerate I2C devices (because back then there
was no kernel support for that), so trigger was hard-coded in the
driver. However the controller behavior is much more reliable if
we use level triggers, and that is how we configured ARM devices,
and how want to configure newer x86 devices as well. All newer
x86 boxes have their I2C devices enumerated in ACPI.

Let's see if platform code (ACPI, DT) described interrupt and
specified particular trigger type, and if so, let's use it instead
of always clobbering trigger with IRQF_TRIGGER_FALLING. We will
still use this trigger type as a fallback if platform code left
interrupt trigger unconfigured.

README 

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
