![]() Some i.MX SoCs (e.g. MX8QXP and MX8QM) contain a system controller that is responsible for controlling the pad setting of the IPs that are present. Communication between the host processor running an OS and the system controller happens through a SCU protocol. This patch classifies the pad settings into two categories: MMIO and SCU. For the original MMIO method, no functional changes except organize them into a few imx_*_mmio() functions. Besides that, we add the SCU based Pad Mux and Pinconf setting support which are implemented in pinctrl-scu.c.

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.
