NAME
       platform_device_register_simple - add a platform-level device and its resources

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

ARGUMENTS
       name
	   base name of the device we're adding

       id
	   instance id

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

       num
	   number of resources

DESCRIPTION
       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 don't fully conform to the Linux
       driver model. In particular, when such drivers are built as modules, they can't be "hotplugged".

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