Guys:


Sorry about starting a new thread, but I was referred to this 
list/thread by a colleague just a few minutes ago.  (OT: it isn't in the 
archives in SF, either!).

I hate to play "me too!", but I also have an SM501 framebuffer driver in 
a partial state of development.  I'd love to collaborate with others to 
get a good version pushed upstream.

One of the challenges I've encountered with this chip is dealing with 
all the "other stuff" it has onboard.  In my driver, I addressed that by 
creating a whole new bus similar to what Nico did for the UCB1400.  I 
was in the process of getting AC97 working when I figured out that that 
part of the chip is so braindead, it isn't worth using--- at least on 
ARM platforms that don't have DMA (which was my case).

In an upcoming project I need to use the USBH, so I'll be revisiting 
this issue again soon.  I have also cc'd others who have worked with me 
on this chip.

I'd be happy to post code if that makes sense.  Or to host a CVS repo or 
something.

We have a solution based on an central device in drivers/mfd
which creates a set of sub-devices that are used by the invidicual
drivers

We too ;), and use on our board: http://www.varma-el.com/en/prod?cls=sbc

Anyone have objections about berlios.de SVN for a sm501 staff?
