menuconfig MELLANOX_PLATFORM
bool "Platform support for Mellanox hardware"
depends on X86 || ARM || ARM64 || COMPILE_TEST
help
Say Y here to get to see options for platform support for
Mellanox systems. This option alone does not add any kernel code.
If you say N, all options in this submenu will be skipped and disabled.

config MLXREG_HOTPLUG
tristate "Mellanox platform hotplug driver support"
depends on HWMON
depends on I2C
select REGMAP
help
This driver handles hot-plug events for the power suppliers, power
cables and fans on the wide range Mellanox IB and Ethernet systems.
config MLXREG_IO
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.
config MLXREG_LC
tristate "Mellanox line card platform driver support"
depends on HWMON
depends on I2C
select REGMAP
help
This driver provides support for the Mellanox MSN4800-XX line cards,
which are the part of MSN4800 Ethernet modular switch systems
providing a high performance switching solution for Enterprise Data
Centers (EDC) for building Ethernet based clusters, High-Performance
Computing (HPC) and embedded environments.
config MLXBF_TMFIFO
tristate "Mellanox BlueField SoC TmFifo platform driver"
depends on ARM64
depends on ACPI
depends on VIRTIO_CONSOLE && VIRTIO_NET
help
Say y here to enable TmFifo support. The TmFifo driver provides
platform driver support for the TmFifo which supports console
and networking based on the virtio framework.
config MLXBF_BOOTCTL
tristate "Mellanox BlueField Firmware Boot Control driver"
depends on ARM64
depends on ACPI
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.
config MLXBF_PMC
tristate "Mellanox BlueField Performance Monitoring Counters driver"
depends on ARM64
depends on HWMON
depends on ACPI
help
Say y here to enable PMC support. The PMC driver provides access
to performance monitoring counters within various blocks in the
Mellanox BlueField SoC via a sysfs interface.
config NVSW_SN2201
tristate "Nvidia SN2201 platform driver support"
depends on HWMON
depends on I2C
select REGMAP_I2C
help
This driver provides support for the Nvidia SN2201 platform.
The SN2201 is a highly integrated for one rack unit system with
L3 management switches. It has 48 x 1Gbps RJ45 + 4 x 100G QSFP28
ports in a compact 1RU form factor. The system also including a
serial port (RS-232 interface), an OOB port (1G/100M MDI interface)
and USB ports for management functions.
The processor used on SN2201 is Intel Atom®Processor C Series,
C3338R which is one of the Denverton product families.
System equipped with Nvidia®Spectrum-1 32x100GbE Ethernet switch.
