Hi,
Greg's post earlier today about the status of the staging tree drew my
attention to the panel driver.
> - panel. Another one that should be simple to merge. Anyone?
And as I have some spare time on my hands and
thought I might takeover this task - or atleast add some improvements. :)
I think this project might suit me well, as I already wrote some lcd-related
drivers (e.g. for an powerpc eval board) and moreover I have one of these
lcds here :)
I alread had a look at the source and before really getting started with it I
want to discuss one of the issues in the TODO list:
- see if all of this could be easier done in userspace instead.
My question is why not using lcdproc [1] instead - it can access keypads and
HD44780-like 8-bit parallel LCDs.
So what do you think?
Willy, the author of the driver, answered my question like this:

I'm looking forward to your replies ;)
Thanks,
Peter
