1* Samsung's High Speed I2C controller
2
3The Samsung's High Speed I2C controller is used to interface with I2C devices
4at various speeds ranging from 100khz to 3.4Mhz.
5
6Required properties:
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
14				on Exynos5260 SoCs.
15	-> "samsung,exynos7-hsi2c", for i2c compatible with HSI2C available
16				on Exynos7 SoCs.
17
18  - reg: physical base address of the controller and length of memory mapped
19    region.
20  - interrupts: interrupt number to the cpu.
21  - #address-cells: always 1 (for i2c addresses)
22  - #size-cells: always 0
23
24  - Pinctrl:
25    - pinctrl-0: Pin control group to be used for this controller.
26    - pinctrl-names: Should contain only one value - "default".
27
28Optional properties:
29  - clock-frequency: Desired operating frequency in Hz of the bus.
30    -> If not specified, the bus operates in fast-speed mode at
31       at 100khz.
32    -> If specified, the bus operates in high-speed mode only if the
33       clock-frequency is >= 1Mhz.

35Example:
36
37hsi2c@12ca0000 {
38	compatible = "samsung,exynos5250-hsi2c";
39	reg = <0x12ca0000 0x100>;
40	interrupts = <56>;
41	clock-frequency = <100000>;
42
43	pinctrl-0 = <&i2c4_bus>;
44	pinctrl-names = "default";
45
46	#address-cells = <1>;
47	#size-cells = <0>;
48
49	s2mps11_pmic@66 {
50		compatible = "samsung,s2mps11-pmic";
51		reg = <0x66>;
52	};
53};
