16   In case the HSI2C controller is encapsulated within USI block (it's the case
17   e.g. for Exynos850 and Exynos Auto V9 SoCs), it might be also necessary to
18   define USI node in device tree file, choosing "i2c" configuration. Please see
19   Documentation/devicetree/bindings/soc/samsung/exynos-usi.yaml for details.

45       If specified, the bus operates in high-speed mode only if the
46       clock-frequency is >= 1MHz.
