[PATCH 00/19] OMAP: DSS2 v5 intro

Split arch/arm/plat-omap/include/mach/omapfb.h into two files:

include/linux/omapfb.h - ioctls etc for userspace and some kernel
stuff for board files
drivers/video/omap/omapfb.h - for omapfb internal use

This cleans up omapfb.h and also makes it easier for the upcoming new
DSS driver to co-exist with the old driver.

Please read the FAQ at http://www.tux.org/lkml/

Add a Video RAM manager for OMAP 2 and 3 platforms. VRAM manager is used
to allocate large continuous blocks of SDRAM or SRAM. The features VRAM
manager has that are missing from dma_alloc_* functions are:

- Support for OMAP2's SRAM
- Allocate without ioremapping
- Allocate at defined physical addresses
- Allows larger VRAM area and larger allocations

The upcoming DSS2 uses VRAM manager.

VRAM area size can be defined in kernel config, board file or with
kernel boot parameters. Board file definition overrides kernel config,
and boot parameter overrides kernel config and board file.

VRFB rotation engine is a block in OMAP2/3 that offers 12 independent
contexts that can be used for framebuffer rotation.

Each context has a backend area of real memory, where it stores the
pixels in undisclosed format. This memory is offered to users via 4
virtual memory areas, which see the same memory area in different
rotation angles (0, 90, 180 and 270 degrees).

Tomi,

could you please kindly ask Stephen (CCed) to include the DSS2 tree into
linux-next, because you are going to merge it the next merge window, and
there does not seem to be any blocker for this.

Being in linux-next for a while is really important.

Stephen, would this be possible? DSS2 driver is rather big piece of
code, even if it's quite isolated, so it would be nice to have it in
linux-next.

What does it require from me? A git tree, obviously, but what should it
be based on?

Ah, I just realized that DSS2 patches depend on patches from Tony's
tree. I guess I should base my tree on top of some Tony's tree that is
going to linux-next?

Or I can merge them into my for-next if that's OK with everybody. This
merge cycle is a pain for omap as we've moved all the common headers from
include/mach to include/plat.

Tomi should still send a separate pull request for Linus for the
DSS2 patches.

Regards,

Tony

I thought everything stable which you are going to merge next merge
window should be in the next branch by default. Especially these massive
re-names which potentially may break many things, right?

Yes, the renames are already there.

OK. The only dependency is the the move of the headers.

Tomi, can you please rebase your patches on top of the "7xx-iosplit-plat-merge"
branch in linux-omap tree? This is commit 8171d88089ad63fc442b2bf32af7c18653adc5cb,
and it should stay static.

Please don't rebase on the for-next branch in linux-omap tree, that's still
changing.

Regards,

Tony

I rebased DSS2 on top of 8171d88089ad63fc442b2bf32af7c18653adc5cb. It
can be found from git://gitorious.org/linux-omap-dss2/linux.git for-next
branch.

I'm ok with Tony pulling DSS2 to his next-branch, or Stephen pulling
directly, which ever works easier for you.
