Shravan Kumar Ramani 1a218d312e platform/mellanox: mlxbf-pmc: Add Mellanox BlueField PMC driver
The performance modules in BlueField are present in several hardware
blocks and each block provides access to these stats either through
counters that can be programmed to monitor supported events or
through memory-mapped registers that hold the relevant information.
The hardware blocks that include a performance module are:
 * Tile (block containing 2 cores and a shared L2 cache)
 * TRIO (PCIe root complex)
 * MSS (Memory Sub-system containing the Memory Controller and L3 cache)
 * GIC (Interrupt controller)
 * SMMU (System Memory Management Unit)
The mlx_pmc driver provides access to all of these performance modules
through a hwmon sysfs interface.

v2 --> v3
Update copyright info.

v1 --> v2
Remove unused headers.
Add comma to arrays where last line is not a termination.
Use kstrtoint in place of sscanf.
UUID manipulation follows drivers/platform/mellanox/mlxbf-bootctl.c

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 REGMAP
depends on HWMON
depends on I2C
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 REGMAP
depends on HWMON
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 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.
