Update DSS2 patches for latest kernel changes

Update DSS2 patches for latest kernel changes

[Hiremath, Vaibhav]

Hi Tomi,

(Tomi, Sorry for resending it again, somehow last mail did not reach to list, so sending it again by removing patches attached.)

DSS2 patches needs to be updated against the latest kernel changes, especially after commit "omap: headers: Move remaining headers from include/mach to include/plat"

Since this patch has already merged to "for-next", I have done required modification to your commits (for both master and pm branch), keeping rest of the stuff as is. 
I could able to validate it only on OMAP3EVM (since I don't have other EVMs) with DPI/Venc interface. 

If you could validate rest of the interfaces then we can update the DSS2 branch with latest kernel.

You can access the patches from the repository - 

http://arago-project.org/git/people/?p=vaibhav/ti-psp-omap-video.git;a=shortlog;h=refs/heads/ti_display


Thanks,
Vaibhav

Thanks, although I have already done that =). I'm in the process of
integrating new patches (mostly VRFB and DSI fixes) to the DSS patch
set. When I'm done I'll post them.

[Hiremath, Vaibhav] I cross-checked your repository and could not find anything there, so I started rebasing it myself.

Anyway, please let me know once you are done with it.

Thanks,

I'm not done with it yet, but I pushed the current tree, based on
linux-next, to master-new branch in
git://gitorious.org/linux-omap-dss2/linux.git (Actually, it's still
pushing... Either gitorious or Nokia's proxies are really slow today).

That branch has been squashed with all the latest changes. I need to do
more testing, but it seemed to work with a board with a DSI display. SDP
also boots fine, but the LCD has (again) a green tint. And using DSI PLL
for pixel clock didn't seem to work. I guess there's (again) some power
missing. I hope I'll have time next week to go through these.

I was planning to also publish the non-squashed branch, but I seem to
have messed things up a bit and I don't have that branch saved. I can
try harder to find it if someone requests it. But as a hint what's been
changed since the last major squash, here's a list of commit names which
will probably give an idea. Mostly VRFB and DSI things:

Taal: Handle error when initializing panel
Taal: fix too long line
Taal: allow interrupting of memory read
Taal: Implement ESD check
Taal: Add missing field initialization
DSS2: OMAPFB: remove full screen update from SETUP_PLANE ioctl

DSS2: OMAPFB: Fix OMAPFB_GET_CAPS ioctl
DSS2: Add OMAP_DSS_DISPLAY_CAP_TEAR_ELIM display capability

DSS2: OMAPFB: Split resolution bounds checking into a new function
DSS2: Reject invalid color modes
DSS2: Add RGB12U where appropriate
DSS2: OMAPFB: Remove unused variable

A side note. I suggest you to send DSS2 once again for review to
lkml/linux-omap. Even if you do not get comments, it is good to have
just yet another "it was sent out here" reference, which you can put to
your pull request later.

[Hiremath, Vaibhav] Thanks for the update, I will pull it and merge EVM support on this. I will validate it on EVM.

[Hiremath, Vaibhav] If you could share all the current active development with me, I can help you validating this on EVM.

Yes, that's my plan. I just need to find time to test things first (and
fix those couple SDP problems), before posting it for review.
