BMA253 has two interrupt pins (INT1 and INT2) that can be configured independently. At the moment the bmc150-accel driver does not make use of them but it might be able to in the future, so it's useful to already specify all available interrupts in the device tree. Set maxItems: 2 for interrupts to allow specifying a second one. This is necessary as preparation to move the bosch,bma254 compatible from bosch,bma180.yaml to bosch,bma255.yaml since bma180 allows two interrupts, but BMA254 is better supported by the bmc150-accel driver.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
