class ReferenceProperty

Defined at line 130 of file ../../sdk/lib/driver/devicetree/visitors/property-parser.h

Represents a property that contains one or more references to other devicetree nodes (phandles),

each potentially followed by a set of arguments (cells).

For example: `gpios =

&gpio

1 1 2>,

&gpio

2 3 4 0>;`

This property contains two references: one to `gpio1` with cells `{1, 2}` and one to `gpio2` with

cells `{3, 4, 0}`.

void ReferenceProperty (PropertyName name, std::variant<PropertyName, uint32_t> cell_specifier, bool required)

Constructs a `ReferenceProperty` parser.

The `cell_specifier` determines how many cells (u32 values) follow each phandle in the

property. It can be either:

1. A `PropertyName` (e.g., "#interrupt-cells"): The number of cells is determined by reading

the value of that property from the referenced node. This is the most common case.

Example:

intc: interrupt-controller

.. {

#interrupt-cells =

2>;

};

my_device: my_device

.. {

interrupts =

&intc

1 8>; // Parsed using `ReferenceProperty("interrupts",

// "#interrupt-cells")`.

};

2. A `uint32_t`: A fixed number of cells that applies to all references within this property.

Example:

my_device: my_device

.. {

mboxes =

&mbox

0>,

&mbox

1>; // Parsed using `ReferenceProperty("mboxes", 1)`.

};
