USB on MPC8272

USB on MPC8272

[Nathael PAJANI]

Hi all!


I have to support USB hcd for an Actis board based on a MPC8248 
processor. I already have a 2.6.9 linux kernel running fine on it, and 
actualy have to use it rather than a newer one.
I'm actualy looking for existing or ongoing jobs.


Mike Rapoport:

When you say "I'm running linux 2.6.12.3 with "custom" USB host driver."
Are you speaking of this one: "http://cpm2usb.sourceforge.net./" or another?


Kumar Gala:
On the thread "MPC8555 USB host support" you're asking:
"Also, are you aware of Freescale's driver for this?"

Where is this support located? (which files or directories)


Thanks.


PS: Thanks a lot for people who helped me when porting linux 2.6.13 to 
the Actis board VSBX6560 whith MPC8560 processor. It's finished. (Or at 
least, no bug reports yet :)
How to commit a patch to the main kernel tree?

Dear Nathael,
As far as I understand there are several drivers for the MPC8272 usb 
host controller, and none of them is in
official kernel tree.
There's a driver in Metrowerks BSP for linux 2.6 for MPC8272 (the 
Freescale driver), an orignally mpc8xx driver by Brad Parker ported to 
linux 2.4 for MPC8272 by Pantelis Antoniou, there ought to be USB driver 
by ArabellaSW also.
My driver ("http://cpm2usb.sourceforge.net./") is a port of the Brad 
Parker's driver to linux 2.6 with some modifications.

And, ideally we would like to see one driver get into the linux  
source tree that everyone is happy with.  I'm told by someone that  
the FSL driver is suppose to have working host support "was tested/ 
verified with keyboard/mouse/diskdrives/network".

We have that FS driver rework in progress, but even now it's quite hard to estimate the finish. The result will proceed upstream, anyway, but this is long-term I afraid.
