	  Say Y here if you want kernel support for the integrated memory
	  controller (iMC) SMBus engine found in Intel Skylake-X / Cascade
	  Lake-X processors (socket LGA 2066, platform X299, PCU function
	  8086:2085).

	  The engine is exposed through the PCI configuration space of the
	  PCU function.  Those registers are unreachable through the config
	  accessors the platform selects for the first 256 bytes, so the
	  driver reaches them through the memory-mapped (ECAM) path.  Two
	  I2C adapters are registered, one per hardware SMBus channel,
	  allowing access to DDR4 DIMM SPD EEPROMs (0x50-0x57) and thermal
	  sensors from userspace via standard i2c-tools and lm-sensors.

	  Firmware, SMM, a BMC or CLTT may drive the same engine and no
	  generic arbitration mechanism is known.  The driver therefore
	  refuses to bind unless the allow_unsafe_access module parameter
	  is enabled.  See Documentation/i2c/busses/i2c-imc-skylake.rst.

	  If unsure, say N.  This driver is only useful on Intel X299 desktop
	  / HEDT systems with the Skylake-X or Cascade Lake-X CPU.

	  This driver can also be built as a module.  If so, the module
	  will be called i2c-imc-skylake.
