lcd rotation in omapfb_main.c

lcd rotation in omapfb_main.c

[twebb]

I'm trying to start up the LCD panel on a new omap35xx-based platform
in portrait mode, though the native orientation of the display is
landscape.  I'm running linux-2.6.27-omap1.  However, when I change
"def_rotate" to 90 in omapfb_main.c, it doesn't seem to make any
difference in the orientation of the display.  Any ideas why this
might be happening?  Could there be outstanding fixes/patches I need?

Thanks,
twebb

change it to 1 or something ... btw. this should be configurable through some 
platform_data. Also, dont bring up new platform on deprecated kernel.

Since when is linux-omap v2.6.27-omap1 deprecated?  It's only 5 months
old!  Am I missing something here?

And the def_rotate is defined to be in degrees - I'm pretty sure
setting it to 1 won't work.

Deprecated is probably a poor choice of words, but if you are indeed
bringing up a new platform, doing so on the newest Kernel you can find
will ensure that bringing in newer changes from the time you begin
your work will be easier.

The L-O tree is already about 2.6.30, so you're essentially 3
revisions out and you're just setting yourself up for a bunch of work
to port numerous changes into your Kernel.

And as Greg KH would probably say, 5 months in Kernel development land
is a really long period of time. :)

It got deprecated when 2.6.28 was released

Yes, it seems you have missed the release of 2.6.28 and 2.6.29.

Thanks for the clarification.  Maybe you could help me understand
something about the l-o tree.  From what I see on the git, the latest
tagged l-o version is 2.6.30-rc2, but my understanding is that only
tags that include "-omapX" have had the latest omap patches applied to
it.  So I'm not sure what the best choice would be for the 'newest
kernel I can find'.  Maybe another way to ask this is which would
offer better, reasonably stable, omap support: tagged tree
v2.6.28-omap1 or v2.6.29, or head omap-2.6.28 or omap-2.6.29 or
omap-fixes?

Thanks.

I'm not an omap person anymore (though I'll miss working on my omap devices). 
But, according to README[1], the git address is [2] and you should be fine 
just doing git clone [3] on it.
