Re: [jornada] Sound on Jornada 56x

Jake,

Thank you for this information. Unfortunately this doesn't help too much. All
this code can already be found in the linux kernel source. The things I need
is how the Jornada talks to those interfaces (i.e. wich GPIO's are used
etc...). With this info, the default L3 and uda1341 stuff can be combined
with the Joranada 56x stuff and the sound output will work. You can have a
look at the sources and you will quickly see how this works with other
devices, e.g. the Ipaq 3xxx devices. Actually, not much info is needed to get
it going.

Thanks anyway.

regards,
Alex
