Kernel-3.10.0-957.el7_i2c-ocores

Device tree configuration for i2c-ocores

Required properties:

• compatible : “opencores,i2c-ocores” or “aeroflexgaisler,i2cmst”
• reg : bus address start and address range size of device
• interrupts : interrupt number
• clock-frequency : frequency of bus clock in Hz
• #address-cells : should be <1>
• #size-cells : should be <0>

Optional properties:

• reg-shift : device register offsets are shifted by this value
• reg-io-width : io register width in bytes (1, 2 or 4)
• regstep : deprecated, use reg-shift above

Example:

i2c0: ocores@a0000000 {
    #address-cells = <1>;
    #size-cells = <0>;
    compatible = "opencores,i2c-ocores";
    reg = <0xa0000000 0x8>;
    interrupts = <10>;
    clock-frequency = <20000000>;

    reg-shift = <0>;    /* 8 bit registers */
    reg-io-width = <1>;    /* 8 bit read/write */

    dummy@60 {
        compatible = "dummy";
        reg = <0x60>;
    };
};
