/**
* struct of_dev_auxdata - lookup table entry for device names & platform_data
* @compatible: compatible value of node to match against node
* @phys_addr: Start address of registers to match against node
* @name: Name to assign for matching nodes
* @platform_data: platform_data to assign for matching nodes
*
* This lookup table allows the caller of of_platform_populate() to override
* the names of devices when creating devices from the device tree. The table
* should be terminated with an empty entry. It also allows the platform_data
* pointer to be set.
*
* The reason for this functionality is that some Linux infrastructure uses
* the device name to look up a specific device, but the Linux-specific names
* are not encoded into the device tree, so the kernel needs to provide specific
* values.
*
* Note: Using an auxdata lookup table should be considered a last resort when
* converting a platform to use the DT. Normally the automatically generated
* device name will not matter, and drivers should obtain data from the device
* node instead of from an anonymous platform_data pointer.
