Questions on new platform submission

[Marc St-Jean <Marc_St-Jean@pmc-sierra.com>]

Hi all,

I am about to submit a new platform and have a few questions to attempt the 
reduce the number of iterations:

1. Should I prepare the patches against the linux.git master?

2. Form previous posts I'm assuming patches for the serial driver 
(drivers/serial/8250.c) should not go to this list but the serial maintainer. 
Is this correct?

3. Same question for USB driver (mostly drivers/usb/host and gadget), should I 
send to a usb maintainer?

Advanced thanks,
Marc
