The Samsung's High Speed I2C controller is used to interface with I2C devices
at various speeds ranging from 100kHz to 3.4MHz.

+ In case the HSI2C controller is encapsulated within USI block (it's the case
+ e.g. for Exynos850 and Exynos Auto V9 SoCs), it might be also necessary to
+ define USI node in device tree file, choosing "i2c" configuration. Please see
