Add new attributes for "next-generation" type systems: - Reset cause indication, when system reset has been caused by the platform reset request through CPLD, by AC power failure, by software power off request through CPLD. by signal asserted by SOC through ACPI register. It introduces more reset causes, which can be monitored after the reboots. - Setting and removing system VPD (EEPROM) hardware write protection. It allows to access VPD during production cycle and prevents VPD corruption on system in field. - Voltage regulator devices configuration update status and version. It allows to monitor configuration update status and current active version for such sort of devices. - PCIe ASIC reset disable - when set ASIC will go down upon PCIe root complex reset, otherwise ASIC will stay up during PCIe root complex reset. - System configuration Ids to provide system static topology identification, like system's static I2C topology, number and type of FPGA devices within the system and so on. Add the existing attribute for "iio" bank selection for system type "msn21xx". All the above attributes are exposed through "sysfs" by "mlxreg-io" 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.
