(

bus

#include <zephyr/devicetree.h>

Value:

        DT_HAS_COMPAT_ON_BUS_STATUS_OKAY(DT_DRV_COMPAT, bus)

Test if any DT_DRV_COMPAT node is on a bus of a given type and has status okay.

This is a special-purpose macro which can be useful when writing drivers for devices which can appear on multiple buses. One example is a sensor device which may be wired on an I2C or SPI bus.

Example devicetree overlay:

&i2c0 {
       temp: temperature-sensor@76 {
                compatible = "vnd,some-sensor";
                reg = <0x76>;
       };
};

Example usage, assuming i2c0 is an I2C bus controller node, and therefore temp is on an I2C bus:

#define DT_DRV_COMPAT vnd_some_sensor
 
DT_ANY_INST_ON_BUS_STATUS_OKAY(i2c) // 1

DT_INST_FOREACH_STATUS_OKAY

#define DT_INST_FOREACH_STATUS_OKAY

(

fn

)

#include <zephyr/devicetree.h>

Value:

        COND_CODE_1(DT_HAS_COMPAT_STATUS_OKAY(DT_DRV_COMPAT),   \
                    (UTIL_CAT(DT_FOREACH_OKAY_INST_,            \
                              DT_DRV_COMPAT)(fn)),              \
                    ())

Call fn on all nodes with compatible DT_DRV_COMPAT and status okay

This macro calls fn(inst) on each inst number that refers to a node with status okay. Whitespace is added between invocations.

Example devicetree fragment:

a {
        compatible = "vnd,device";
        status = "okay";
        foobar = "DEV_A";
};
 
b {
        compatible = "vnd,device";
        status = "okay";
        foobar = "DEV_B";
};
 
c {
        compatible = "vnd,device";
        status = "disabled";
        foobar = "DEV_C";
};

Example usage:

#define DT_DRV_COMPAT vnd_device
#define MY_FN(inst) DT_INST_PROP(inst, foobar),
 
DT_INST_FOREACH_STATUS_OKAY(MY_FN)

This expands to:

MY_FN(0) MY_FN(1)

and from there, to either this:

"DEV_A", "DEV_B",

or this:

"DEV_B", "DEV_A",

No guarantees are made about the order that a and b appear in the expansion.

Note that fn is responsible for adding commas, semicolons, or other separators or terminators.

Device drivers should use this macro whenever possible to instantiate a struct device for each enabled node in the devicetree of the driver's compatible DT_DRV_COMPAT.

Parameters

fn	Macro to call for each enabled node. Must accept an instance number as its only parameter.
