	  Enable support for USI block. USI (Universal Serial Interface) is an
	  IP-core found in modern Samsung Exynos SoCs, like Exynos850 and
	  ExynosAutoV9. USI block can be configured to provide one of the
	  following serial protocols: UART, SPI or High Speed I2C.

	  This driver allows one to configure USI for desired protocol, which
	  is usually done in USI node in Device Tree.

	  Enable the PM code's memory area checksum over sleep. This option
	  will generate CRCs of all blocks of memory, and store them before
	  going to sleep. The blocks are then checked on resume for any
	  errors.

	  Note, this can take several seconds depending on memory size
	  and CPU speed.

	  Set the chunksize in Kilobytes of the CRC for checking memory
	  corruption over suspend and resume. A smaller value will mean that
	  the CRC data block will take more memory, but will identify any
	  faults with better precision.
