Hi -
platform_data is a well established way in Linux to pass configuration data
up to on-board assets from a machine file like mach-xyz.c. It's also
supported to pass platform_data up to devices that are probed asynchronously
from busses like i2c as well, which is very handy.
However AFAIK it's not possible to bind platform_data to probed USB devices
as it stands.
Oh, please no.
platform_data is an ugly non-type-checked anonymous pointer. If you
need to pass data to a driver, use something better designed. A
device tree fragment would work, or provide some kind of query api.
platform_data is definitely the wrong approach.
$ grep platform_data drivers/* -R | wc -l
