The interesting bits start at https://lkml.org/lkml/2015/6/17/383 . Let's see how things go here.) As I understand it, this alias is only useful if there's a corresponding struct platform_device, somewhere. Ie, this alias implies a platform_device that will fire of a "MODALIAS=platform:atmel_flexcom" uevent when it's created. That would be a platform_device using a "atmel_flexcom" name. If that's correct, then I think this MODULE_ALIAS macro isn't needed here, as I couldn't find a platform_device using that name. (But perhaps a patch that adds it is pending, somewhere.)
