N8x0 to mainline patches

I noticed that the patch adding board-n8x0.c seems to be much smaller than the older one used in Linux-OMAP. In particular, it lacks the keymaps and such. Are those somewhere else now? Was the Linux-OMAP keyboard bug taken into consideration for the new keyboard config struct?

It's just not implemented yet. If you look at the plan, you see lots of things we need to implement:

I'm not familiar with the issue. But if it makes sense, sure, we want to include the fix.

Hi,

Just noticed the thread and the link today. I will try and merge some notes I have on the topic (http://natisbad.org/N810/) tomorrow.

I use the patch on a 2.6.30-rc8-omap1 based l-o commit on my N810 and it fixes the reported issue (missing keys).

BTW, I also use the following patch to be able to use the fn key with xorg. One would argue this would be better to handle the issue at another level but it is worth discussing considering what I read on various ML:

When the rx44 keymap support is added back in your quilt set, can we discuss it. IIRC, the same kind of value (i.e. > 255) is also in the rx-51. Any specific reason?

Cheers,
