Detailed Description

Runtime device structure (in ROM) per driver instance.

Field Documentation

[union]

union { ... } device

Reference to the device PM resources (only available if CONFIG_PM_DEVICE is enabled).

api

const void* device::api

Address of the API structure exposed by the device instance.

config

const void* device::config

Address of device instance config information.

data

void* device::data

Address of the device instance private data.

deps

const device_handle_t* device::deps

Optional pointer to dependencies associated with the device.

This encodes a sequence of sets of device handles that have some relationship to this node. The individual sets are extracted with dedicated API, such as device_required_handles_get(). Only available if CONFIG_DEVICE_DEPS is enabled.

dt_meta

const struct device_dt_metadata* device::dt_meta

name

const char* device::name

Name of the device instance.

pm

struct pm_device* device::pm

pm_base

struct pm_device_base* device::pm_base

pm_constraints

struct pm_state_constraint const* device::pm_constraints

pm_constraints_size

size_t device::pm_constraints_size

pm_isr

struct pm_device_isr* device::pm_isr

state

struct device_state* device::state

Address of the common device state.
