Filenames of devictree binding documentation seems to be arbitrary and for me it is unneeded hazzle to find the corresponding documentation for a specific driver. Naming the description the same as the driver is a lot easier and makes sense to me since the driver defines the binding it understands. Also, remove a reference in one source to the binding documentation, since path information easily gets stale.

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>;
|
|
};
|
|
};
