-* Samsung's High Speed I2C controller
-
-The Samsung's High Speed I2C controller is used to interface with I2C devices
-at various speeds ranging from 100khz to 3.4Mhz.
-
-Required properties:
- - compatible: value should be.
- -> "samsung,exynos5-hsi2c", (DEPRECATED)
- for i2c compatible with HSI2C available
- on Exynos5250 and Exynos5420 SoCs.
- -> "samsung,exynos5250-hsi2c", for i2c compatible with HSI2C available
- on Exynos5250 and Exynos5420 SoCs.
- -> "samsung,exynos5260-hsi2c", for i2c compatible with HSI2C available
- on Exynos5260 SoCs.
- -> "samsung,exynos7-hsi2c", for i2c compatible with HSI2C available
- on Exynos7 SoCs.
-
- - reg: physical base address of the controller and length of memory mapped
- region.
- - interrupts: interrupt number to the cpu.
- - #address-cells: always 1 (for i2c addresses)
- - #size-cells: always 0
-
- - Pinctrl:
- - pinctrl-0: Pin control group to be used for this controller.
- - pinctrl-names: Should contain only one value - "default".
-
-Optional properties:
- - clock-frequency: Desired operating frequency in Hz of the bus.
- -> If not specified, the bus operates in fast-speed mode at
- at 100khz.
- -> If specified, the bus operates in high-speed mode only if the
- clock-frequency is >= 1Mhz.
-
-Example:
-
-hsi2c@12ca0000 {
- compatible = "samsung,exynos5250-hsi2c";
- reg = <0x12ca0000 0x100>;
- interrupts = <56>;
- clock-frequency = <100000>;
-
- pinctrl-0 = <&i2c4_bus>;
- pinctrl-names = "default";
-
- #address-cells = <1>;
- #size-cells = <0>;
-
- s2mps11_pmic@66 {
- compatible = "samsung,s2mps11-pmic";
- reg = <0x66>;
- };
-};
