Relation between device registration and driver registration

Hi all,

Today I observe one interesting thing during calling platform_driver_register(). The normal thing is if you have a device, and also a driver, It will be linked. But suppose you want to do some different functionality with the device, like you want to do some initialization of few variables  before starting the real functionality of the device.  So a nice way to do this is create multiple device with the same name but different id and register those usingplatform_device_register() or platform_add_devices().

So now when you will call platform_driver_register(), it will check for all devices available with the same name and the same number of probe() function will be called. Here in probe function you can put your logic for initialization according to your id.

Hope it will help you.
