Linux Device Drivers Development

Text string

The following is one string property:

string-property = "a string"; 

Back in the driver, you should use of_property_read_string()to read a string value. Its prototype is defined as follows:

int of_property_read_string(const struct device_node *np, const 
                        char *propname, const char **out_string) 

The following code shows how you can use it:

const char *my_string = NULL; 
of_property_read_string(pdev->dev.of_node, "string-property", &my_string);
