Man page 9 : platform_device_register_simple

platform_device_register_simple - add a platform-level device and its resources

struct platform_device * platform_device_register_simple(const char *  name , int  id , const struct resource *  res , unsigned int  num );

name
    base name of the device weAqre adding

id
    instance id

res
    set of resources that needs to be allocated for the device

num
    number of resources

This function creates a simple platform device that requires minimal resource and memory management. Canned release function freeing memory allocated for the device allows drivers using such devices to be unloaded without waiting for the last reference to the device to be dropped.

This interface is primarily intended for use with legacy drivers which probe hardware directly. Because such drivers create sysfs device nodes themselves, rather than letting system infrastructure handle such device enumeration tasks, they donAqt fully conform to the Linux driver model. In particular, when such drivers are built as modules, they canAqt be « hotplugged ».

Returns struct platform_device pointer on success, or ERR_PTR on error.
