1 * Samsung's High Speed I2C controller
3 The Samsung's High Speed I2C controller is used to interface with I2C devices
4 at various speeds ranging from 100khz to 3.4Mhz.
7 - compatible: value should be.
8 -> "samsung,exynos5-hsi2c", (DEPRECATED)
9 for i2c compatible with HSI2C available
10 on Exynos5250 and Exynos5420 SoCs.
11 -> "samsung,exynos5250-hsi2c", for i2c compatible with HSI2C available
12 on Exynos5250 and Exynos5420 SoCs.
13 -> "samsung,exynos5260-hsi2c", for i2c compatible with HSI2C available
16 - reg: physical base address of the controller and length of memory mapped
18 - interrupts: interrupt number to the cpu.
19 - #address-cells: always 1 (for i2c addresses)
20 - #size-cells: always 0
23 - pinctrl-0: Pin control group to be used for this controller.
24 - pinctrl-names: Should contain only one value - "default".
27 - clock-frequency: Desired operating frequency in Hz of the bus.
28 -> If not specified, the bus operates in fast-speed mode at
30 -> If specified, the bus operates in high-speed mode only if the
31 clock-frequency is >= 1Mhz.
