  32          Enable support for USI block. USI (Universal Serial Interface) is an
  33          IP-core found in modern Samsung Exynos SoCs, like Exynos850 and
  34          ExynosAutoV9. USI block can be configured to provide one of the
  35          following serial protocols: UART, SPI or High Speed I2C.
  36
  37          This driver allows one to configure USI for desired protocol, which
  38          is usually done in USI node in Device Tree.

  82          going to sleep. The blocks are then checked on resume for any
  83          errors.
  84
  85          Note, this can take several seconds depending on memory size
  86          and CPU speed.

  96          corruption over suspend and resume. A smaller value will mean that
  97          the CRC data block will take more memory, but will identify any
  98          faults with better precision.
