+ tristate "Mellanox platform register access driver support"
+ depends on HWMON
+ select REGMAP
+ help
+ This driver allows access to Mellanox programmable device register
+ space through sysfs interface. The sets of registers for sysfs access
+ are defined per system type bases and include the registers related
+ to system resets operation, system reset causes monitoring and some
+ kinds of mux selection.

+ help
+ The Mellanox BlueField firmware implements functionality to
+ request swapping the primary and alternate eMMC boot partition,
+ and to set up a watchdog that can undo that swap if the system
+ does not boot up correctly. This driver provides sysfs access
+ to the userspace tools, to be used in conjunction with the eMMC
+ device driver to do necessary initial swap of the boot partition.
