[PATCH 00/14] RFC: Consolidation: FUSB200 and FOTG210

[Peter Senna Tschudin]

I'm working on the consolidation of two very similar Faraday EHCI drivers:

drivers/usb/host/fusbh200-hcd.c and drivers/usb/host/fotg210-hcd.c

I'm sending the work unfinished because I have some questions, and I would
appreciate feedback about the changes. As this is not complete work, please do
_not_ apply the series. 

Patches from 01 to 10 are fixes to issues reported by checkpatch, patches 11,
12 and 13 are changes to prepare the code to support multiple devices, and
patch 14 adds parameters from fusb200 into faraday-hcd.

My questions:
 - Is the name faraday-hcd good for the driver that will support both
   fusb200-hcd and fotg210-hcd?

 - Is this patch series in a good direction for consolidating the two drivers?
   I mean it is a lot of patches, and there are many different orders in which
   I could send them.

 - Is it a good idea to include now changes like patches 06, 09 and 10 that may
   have impact on performance? Or should I wait until I can get some hw to
   test?

 - Do you know easy to find and cheap devices using this two host controllers?

 - Should I worry about drivers/usb/gadget/udc/fotg210-udc.c?
