-title: Samsung's Exynos USI (Universal Serial Interface)
-
-maintainers:
-  - Sam Protsenko <semen.protsenko@linaro.org>
-
-description: |
-  USI IP-core provides selectable serial protocol (UART, SPI or High-Speed I2C).
-  USI shares almost all internal circuits within each protocol, so only one
-  protocol can be chosen at a time. USI is modeled as a node with zero or more
-  child nodes, each representing a serial sub-node device. The mode setting
-  selects which particular function will be used.

-    type: boolean
-    description:
-      Enable this property if underlying protocol requires the clock to be
-      continuously provided without automatic gating. As suggested by SoC
-      manual, it should be set in case of SPI/I2C slave, UART Rx and I2C
-      multi-master mode. Usually this property is needed if USI mode is set
-      to "UART".
-
-      This property is optional.
