When userspace calls SET_PLANE ioctl, drm core takes a reference of the fb and
passes control to the update_plane op defined by the drm driver.
In omapdrm, we have a worker thread which queues framebuffers objects received
from update_plane and displays them at the appropriate time.
It is possible that the framebuffer is destoryed by userspace between the time
of calling the ioctl and apply-worker being scheduled. If this happens, the
apply-worker holds a pointer to a framebuffer which is already destroyed.
Take an extra refernece/unreference of the fb in omap_plane_update() to prevent
this from happening. A reference is taken of the fb passed to update_plane(),
the previous framebuffer (held by plane->fb) is unreferenced. This will prevent
drm from destroying the framebuffer till the time it's unreferenced by the
apply-worker.
This is in addition to the exisitng reference/unreference in update_pin(),
which is taken for the scanout of the plane's current framebuffer, and an
unreference the previous framebuffer.

The omapdrm driver requires omapdss panel drivers to expose ops like detect,
set_timings and check_timings. These can be NULL for fixed panel DPI, DBI, DSI
and SDI drivers. At some places, there are no checks to see if the panel driver
has these ops or not, and that leads to a crash.
The following things are done to make fixed panels work:
- The omap_connector's detect function is modified such that it considers panel
types which are generally fixed panels as always connected(provided the panel
driver doesn't have a detect op). Hence, the connector corresponding to these
panels is always in a 'connected' state.
- If a panel driver doesn't have a check_timings op, assume that it supports the
mode passed to omap_connector_mode_valid(the 'mode_valid' drm helper function)
- The function omap_encoder_update shouldn't really do anything for fixed
resolution panels, make sure that it calls set_timings only if the panel
driver has one.

The function bails out from modeset_init if a panel doesn't meet the

come after it, that isn't the correct thing to do, we should go through the rest

When not using DSI PLL to generate the pixel clock, but DSS FCK, the
possible pixel clock rates are rather limited. DSS FCK is currently used
on OMAP2 and OMAP3.
When using Beagleboard with a monitor that supports high resolutions,
the clock rates do not match (at least for me) for the monitor's pixel
clocks within the current threshold in the code, which is +/- 1MHz.
This patch widens the search up to +/- 15MHz. The search is done in
steps, i.e. it first tries to find a rather exact clock, than a bit less
exact, etc. so this should not change the cases where a clock was
already found.

DSS func clock is calculated with prate / div * m. However, the current
omapdss code calculates it with prate * m / div, which yields a slightly
different result when there's a remainder. For example, 432000000 / 14 *
2 = 61714284, but 432000000 * 2 / 14 = 61714285.
In addition to that, the clock framework wants the clock rate given with
clk_set_rate to be higher than the actual (truncated) end result. So, if
prate is 432000000, and div is 14, the real result is 30857142.8571...
We need to call clk_set_rate with 30857143, which gives us a clock of
30857142. That's why we need to use DIV_ROUND_UP() when calling
clk_set_rate.
This patch fixes the clock calculation.

the remainder of the read should be interpreted a full read with
zeros filling out the end of the request.
This behavior is not correct for objects that are not backing rbd
image data. Currently rbd_img_obj_request_callback() assumes it
should be done for all objects.
Change rbd_img_obj_request_callback() so it only does this zeroing
for image objects. Encapsulate that special handling in its own

Pull fbdev fixes from Tomi Valkeinen:
"Since Florian is still away/inactive, I volunteered to collect fbdev
fixes for 3.9 and changes for 3.10. I didn't receive any other fbdev
fixes than OMAP yet, but I didn't want to delay this further as
there's a compilation fix for OMAP1. So there could be still some
fbdev fixes on the way a bit later.
This contains:
- Fix OMAP1 compilation
- OMAP display fixes"
* tag 'fbdev-fixes-3.9-rc4' of git://gitorious.org/linux-omap-dss2/linux:
omapdss: features: fix supported outputs for OMAP4
OMAPDSS: tpo-td043 panel: fix data passing between SPI/DSS parts
omapfb: fix broken build on OMAP1
It enhances the driver for FTDI-based USB serial adapters
