Kernel-3.10.0-957.el7_i2c-gpio

Device-Tree bindings for i2c gpio driver

Required properties:
- compatible = “i2c-gpio”;
- gpios: sda and scl gpio

Optional properties:
- i2c-gpio,sda-open-drain: sda as open drain
- i2c-gpio,scl-open-drain: scl as open drain
- i2c-gpio,scl-output-only: scl as output only
- i2c-gpio,delay-us: delay between GPIO operations (may depend on each platform)
- i2c-gpio,timeout-ms: timeout to get data

Example nodes:

i2c@0 {
compatible = “i2c-gpio”;
gpios = <&pioA 23 0 /* sda */
&pioA 24 0 /* scl */
>;
i2c-gpio,sda-open-drain;
i2c-gpio,scl-open-drain;
i2c-gpio,delay-us = <2>; /* ~100 kHz */
#address-cells = <1>;
#size-cells = <0>;

rv3029c2@56 {
    compatible = "rv3029c2";
    reg = <0x56>;
};
