Data Structures
struct	reset_dt_spec
	Reset controller device configuration. More...

Macros
#define	RESET_DT_SPEC_GET_BY_IDX(node_id, idx)
	Static initializer for a reset_dt_spec.
#define	RESET_DT_SPEC_GET_BY_IDX_OR(node_id, idx, default_value)
	Like RESET_DT_SPEC_GET_BY_IDX(), with a fallback to a default value.
#define	RESET_DT_SPEC_GET(node_id)    RESET_DT_SPEC_GET_BY_IDX(node_id, 0)
	Equivalent to RESET_DT_SPEC_GET_BY_IDX(node_id, 0).
#define	RESET_DT_SPEC_GET_OR(node_id, default_value)    RESET_DT_SPEC_GET_BY_IDX_OR(node_id, 0, default_value)
	Equivalent to RESET_DT_SPEC_GET_BY_IDX_OR(node_id, 0, default_value).
#define	RESET_DT_SPEC_INST_GET_BY_IDX(inst, idx)    RESET_DT_SPEC_GET_BY_IDX(DT_DRV_INST(inst), idx)
	Static initializer for a reset_dt_spec from a DT_DRV_COMPAT instance's Reset Controller property at an index.
#define	RESET_DT_SPEC_INST_GET_BY_IDX_OR(inst, idx, default_value)
	Static initializer for a reset_dt_spec from a DT_DRV_COMPAT instance's 'resets' property at an index, with fallback.
#define	RESET_DT_SPEC_INST_GET(inst)    RESET_DT_SPEC_INST_GET_BY_IDX(inst, 0)
	Equivalent to RESET_DT_SPEC_INST_GET_BY_IDX(inst, 0).
#define	RESET_DT_SPEC_INST_GET_OR(inst, default_value)    RESET_DT_SPEC_INST_GET_BY_IDX_OR(inst, 0, default_value)
	Equivalent to RESET_DT_SPEC_INST_GET_BY_IDX_OR(node_id, 0, default_value).

Functions
int	reset_status (const struct device *dev, uint32_t id, uint8_t *status)
	Get the reset status.
static int	reset_status_dt (const struct reset_dt_spec *spec, uint8_t *status)
	Get the reset status from a reset_dt_spec.
int	reset_line_assert (const struct device *dev, uint32_t id)
	Put the device in reset state.
static int	reset_line_assert_dt (const struct reset_dt_spec *spec)
	Assert the reset state from a reset_dt_spec.
int	reset_line_deassert (const struct device *dev, uint32_t id)
	Take out the device from reset state.
static int	reset_line_deassert_dt (const struct reset_dt_spec *spec)
	Deassert the reset state from a reset_dt_spec.
int	reset_line_toggle (const struct device *dev, uint32_t id)
	Reset the device.
static int	reset_line_toggle_dt (const struct reset_dt_spec *spec)
	Reset the device from a reset_dt_spec.
