d01e4afdbb ARM: arm-soc: Cleanups on various subarchitectures
Cleanup patches for various ARM platforms and some of their associated
 drivers. There's also a branch in here that enables Freescale i.MX to be
 part of the multiplatform support -- the first "big" SoC that is moved
 over (more multiplatform work comes in a separate branch later during
 the merge window).

5aaee69d7f OMAPDSS: DISPC: get dss clock rate from dss driver
Dispc currently gets dispc's fck with clk_get() and uses clk_get_rate()
to get the rate for scaling calculations. This causes a problem with
common clock framework, as omapdss uses the dispc functions inside a
spinlock, and common clock framework uses a mutex in clk_get_rate().

Looking at the DSS clock tree, the above use of the dispc fck is not
quite correct. The DSS_FCLK from PRCM goes to DSS core block, which has
a mux to select the clock for DISPC from various options, so the current
use of dispc fck bypasses that. Fortunately we never change the dispc
clock mux for now.

To fix the issue with clk_get_rate(), this patch caches the dss clock
rate in dss.c when it is set. Dispc will then ask for the clock rate
from dss. While this is not very elegant, it does fix the issue, and
it's not totally wrong when considering that the dispc fck actually
comes via dss.

In the future we should probably look into common clock framework and
see if that could be used to represent the DSS clock tree properly.

Here's the large driver core updates for 3.8-rc1.
 
 The biggest thing here is the various __dev* marking removals.  This is
 going to be a pain for the merge with different subsystem trees, I know,
 but all of the patches included here have been ACKed by their various
 subsystem maintainers, as they wanted them to go through here.

 and just send you one with the other fixes/updates and then, after
 3.8-rc1 is out, do the rest of the removals to ensure we catch them all,
 it's up to you.  The merges should all be trivial, and Stephen has been
 doing them all in linux-next for a few weeks now quite easily.
 
 Other than the __dev* marking removals, there's nothing major here, some
 firmware loading updates and other minor things in the driver core.
 
 All of these have (much to Stephen's annoyance), been in linux-next for
 a while.

avoid this to make the compat code to work.

Instead of the output drivers registering for dispc interrupts, we

when DISPC FRAMEDONE interrupt happens. The compat layer is improved
accordingly to do the call to the framedone handler.

The output drivers need some operations from the overlay managers, like
enable and set_timings. These will affect the dispc registers, and need
to be synchronized with the composition-side changes with overlays and
overlay managers.

We want to handle these calls in the apply.c in the compatibility mode,
but when in non-compat mode, the calls need to be handled by some other
component (e.g. omapdrm).

To make this possible, this patch creates a set of function pointers in
a dss_mgr_ops struct, that is used to redirect the calls into the
correct destination.

The non-compat users can install their mgr ops with
dss_install_mgr_ops() function.

We currently attach an output to a dssdev in the initialization code for

output entity represents (surprisingly) an output of DSS, which is
managed by an output driver. The output driver also handles adding new
dssdev's for that particular output.

It makes more sense to make the output-dssdev connection in the output
driver. This is also in line with common display framework.

09a8c45cbb OMAPFB: remove warning when trying to alloc at certain paddress
omapfb gives a WARN_ONCE if a predefined physical address is given for
allocating the framebuffer memory, as this is not currently supported.

However, the same warning happens if omapfb fails to allocate memory
during runtime, as when the allocation has failed, omapfb tries to
re-allocate the old memory with the physical address of the old memory
area.

Remove the warning from omapfb_alloc_fbmem, as it serves no purpose on

we only warn if physical address is given via omapfb module parameters.

b41deecbda OMAPFB: simplify locking
Kernel lock verification code has lately detected possible circular
locking in omapfb. The exact problem is unclear, but omapfb's current
locking seems to be overly complex.

This patch simplifies the locking in the following ways:

- Remove explicit omapfb mem region locking. I couldn't figure out the
  need for this, as long as we take care to take omapfb lock.

- Get omapfb lock always, even if the operation is possibly only related
  to one fb_info. Better safe than sorry, and normally there's only one
  user for the fb so this shouldn't matter.

- Make sure fb_info lock is taken first, then omapfb lock.

With this patch the warnings about possible circular locking does not
happen anymore.

makes sense as the function should only deal with fb memory. Also, this
seems to avoid a lockdep warning about possible circular locking.
However, the exact reason for that warning is still unclear.

45c3eb7d3a ARM: OMAP: Move plat-omap/dma-omap.h to include/linux/omap-dma.h
Based on earlier discussions[1] we attempted to find a suitable
location for the omap DMA header in commit 2b6c4e73 (ARM: OMAP:
DMA: Move plat/dma.h to plat-omap/dma-omap.h) until the conversion
to dmaengine is complete.

Unfortunately that was before I was able to try to test compile
of the ARM multiplatform builds for omap2+, and the end result
was not very good.

So I'm creating yet another all over the place patch to cut the
last dependency for building omap2+ for ARM multiplatform. After
this, we have finally removed the driver dependencies to the
arch/arm code, except for few drivers that are being worked on.

The other option was to make the <plat-omap/dma-omap.h> path
to work, but we'd have to add some new header directory to for
multiplatform builds.

Or we would have to manually include arch/arm/plat-omap/include
again from arch/arm/Makefile for omap2+.

Neither of these alternatives sound appealing as they will
likely lead addition of various other headers exposed to the
drivers, which we want to avoid for the multiplatform kernels.

Since we already have a minimal include/linux/omap-dma.h,
let's just use that instead and add a note to it to not
use the custom omap DMA functions any longer where possible.

Note that converting omap DMA to dmaengine depends on
dmaengine supporting automatically incrementing the FIFO
address at the device end, and converting all the remaining
legacy drivers. So it's going to be few more merge windows.

bdb736abfa OMAPDSS: Use only "omapdss_dss" platform device to get context lost count
When enabling a hwmod, omap_hwmod refers to the register mentioned in the
hwmod struct's member 'prcm.omap4.context_offs' to see whether context was
lost or not. It increments the context lost count for the hwmod and then clears
the register.

All the DSS hwmods have the same register(RM_DSS_DSS_CONTEXT) as context_offs.
When DSS is enabled, the first hwmod to be enabled is the "dss_core" hwmod since
it's corresponding platform device is the parent platform device("omapdss_dss").
The dss_core hwmod updates it's context lost count correctly and clears the
register. When the hwmods corresponding to the children platform devices are
enabled, they see that the register is clear, and don't increment their context
lost count. Therefore, all the children platform devices never report a loss in
context.

The DISPC driver currently gets the context lost count for DSS power domain from
it's corresponding platform device instance("omapdss_dispc"). The DISPC platform
device is one of the child devices, and it's corresponding hwmod("dss_dispc")
doesn't report the context lost count correctly.

Modify dss_get_ctx_loss_count() such that it always takes the "omapdss_dss"
platform device as it's input, move the function to dss.c so that it has access
to that platform device.

1de8e129f5 OMAPDSS: DPI: fix crash with dpi_verify_dsi_pll()
If the DSI support has not been compiled in or the SoC doesn't have DSI
hardware, dpi_get_dsidev() returns NULL. This NULL is passed to
dpi_verify_dsi_pll() causing a crash. The bug was added with commit
0e8276ef75 (OMAPDSS: DPI: always use DSI
PLL if available).

Fix this by checking if dsidev is NULL before calling
dpi_verify_dsi_pll().

e7b4271875 drivers/video: fsl-diu-fb: store EDID data in the global object
Although the DIU driver creates five framebuffer devices, only the first
one controls the physical display.  The remaining four are virtual "AOIs".
Therefore, the EDID data should be stored in the global fsl_diu_data
object, instead of the per-framebuffer object.

ceb001b077 drivers/video: fsl-diu-fb: don't touch registers for unused features
We don't use the writeback buffer, so don't initialize the registers for
that feature.

The default value for SYN_POL is already zero, so don't re-initialize it.

Writing the INT_STATUS register does nothing.

The value that we write to the PLUT register only makes sense on the
MPC8610 and P1022, so don't touch that register on the MPC5121.
