| 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. |
