| 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. |
