-* Marvell MV64XXX I2C controller
-
-Required properties :
-
- - reg : Offset and length of the register set for the device
- - compatible : Should be either:
- - "allwinner,sun4i-a10-i2c"
- - "allwinner,sun6i-a31-i2c"
- - "marvell,mv64xxx-i2c"
- - "marvell,mv78230-i2c"
- - "marvell,mv78230-a0-i2c"
- * Note: Only use "marvell,mv78230-a0-i2c" for a
- very rare, initial version of the SoC which
- had broken offload support. Linux
- auto-detects this and sets it appropriately.
- - interrupts : The interrupt number
-
-Optional properties :
-
- - clock-frequency : Desired I2C bus clock frequency in Hz. If not set the
-default frequency is 100kHz
-
- - resets : phandle to the parent reset controller. Mandatory
- whenever you're using the "allwinner,sun6i-a31-i2c"
- compatible.
-
- - clocks: : pointers to the reference clocks for this device, the
- first one is the one used for the clock on the i2c bus,
- the second one is the clock used to acces the registers
- of the controller
-
- - clock-names : names of used clocks, mandatory if the second clock is
- used, the name must be "core", and "reg" (the latter is
- only for Armada 7K/8K).
-
-Examples:
-
- i2c@11000 {
- compatible = "marvell,mv64xxx-i2c";
- reg = <0x11000 0x20>;
- interrupts = <29>;
- clock-frequency = <100000>;
- };
-
-For the Armada XP:
-
- i2c@11000 {
- compatible = "marvell,mv78230-i2c", "marvell,mv64xxx-i2c";
- reg = <0x11000 0x100>;
- interrupts = <29>;
- clock-frequency = <100000>;
- };
-
-For the Armada 7040:
-
- i2c@701000 {
- compatible = "marvell,mv78230-i2c";
- reg = <0x701000 0x20>;
- interrupts = <29>;
- clock-frequency = <100000>;
- clock-names = "core", "reg";
- clocks = <&core_clock>, <®_clock>;
- };
