Adding 'of_platform' bus support to the platform driver

[R.Patil at mei-india.com]

Hello,

We are working on one of the platform drivers for our board (based on MPC8313ERDB). Previously, this driver was supporting platform bus but now we want to change it to support 'of_platform' bus. While supporting platform bus, the platform device structure is initialised in board setup file, and platform device is registered using 'platform_device_register_simple' call. 

Now if we want to support 'of_platform' bus, the information related to the the device will be extracted from device tree in the platform driver itself and we would not be required to call 'platform_device_register_simple' to register the platform device. Is this understanding correct?

Thanks and Regards,
