The SSD130x OLED display reset signal is active low. Now the reset sequence is implemented in such a way that users are forced to define reset-gpios as GPIO_ACTIVE_HIGH in DT to make the reset work. Do not hard code the active-low sequence into the driver but instead allow the user to specify the gpio as GPIO_ACTIVE_LOW to reflect the real world.

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.
