parent device for the device we're adding
base name of the device we're adding
platform specific data for this platform device
size of platform specific data
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

NULL-terminated list of attribute groups to be created
string for the device's name
This function can be used by char device classes. A struct device will be created in sysfs, registered to the specified class. Additional
attributes specified in the groups parameter will also be created automatically.
A "dev" file will be created, showing the dev_t for the device, if the dev_t is not 0,0. If a pointer to a parent struct device is passed
in, the newly created struct device will be a child of that device in sysfs. The pointer to the struct device will be returned from the
call. Any further sysfs files that might be required can be created using this pointer.
Returns struct device pointer on success, or ERR_PTR on error.
the struct class passed to this function must have previously been created with a call to class_create.
