GFX: Fix display init by moving mdfld_dsi_pkg_sender_init() earlier
The DSI-LVDS bridge driver code moved the mdfld_dsi_pkg_sender_init() call
later in mdfld_dsi_output_init(). This breaks display init for command mode
panels, so move it back.

At the moment we need to support user space libraries compiled both with

Note that this option is only a poor workaround for a problem in user

code here.
Also move -DSUPPORT_MEMINFO_IDS to where similar defines are specified
and remove -DPVR_SECURE_HANDLES which is already specified elsewhere.

bLastInScene is supposed to optimize on some of the cache flushes before
starting a rendering operation. It's still under investigation whether
it's safe to do this though. Until we figure this out, ignore this
parameter and perform cache flushes as before.

gfx: pvr: fix IOCTL ABI w.r.t MEMINFO_IDS, SECURE_FD_EXPORT, SECURE_HANDLES
Recent PVR user space library versions extended some of the IOCTL
parameter structures, effectively changing the ABI. These extensions
are optionally built based on the above Kconfig options. They are
in fact only workarounds for problems in those library versions, so
after we fixed those problems in the libraries properly we shoud remove
the support for them in the driver.
For other library versions not depending on these features, enabling
them won't have any functional difference. The net result is that we
remove the ABI dependency and can use both types of library versions
with the same driver binary.

GFX: Add tc358764xbg/65xbg MIPI DSI-LVDS bridge chip support
Add preliminary support for Toshiba tc358764xbg/65xbg MIPI DSI-LVDS bridge
chip. Set panelid=TC35876X on the kernel command line to enable support.
ISSUES/TODO:
* The I2C device and GPIO line numbers should be defined in firmware,
rather than hard coded in the driver. Consequently, this implementation
only works on dv0.9.
* The driver exposes functions that are called from here and there in the
display controller driver, even before the driver has been initialized.
* The implementation touches DSI clock registers, among other things,
directly without locking. It seems to usually work by accident.
* Many of the problems in the implementation (like the above) come from the
fact that the whole display controller driver lacks proper infrastructure
for pretty much everything, including easily adding new display
drivers. It's not trivial to fix this when adding a new driver.
* Fix checkpatch/sparse errors.
This patch is based on earlier work by (at least) Srinivas Pandruvada, Paul
Drews, Ke Ai, and Michael Demeter.

GFX: Replace the BIT<N> macros with the generic BIT(N) from bitops.h
Replace BIT<N> macros with generic BIT(N) macros from bitops.h. The bulk of
the change was done using sed:
sed -i 's/\([^A-Za-z0-9_]*\)\(BIT\)\([0-9][0-9]*\)\([^A-Za-z_]*\)/\1\2(\3)\4/g' *.c *.h
Then manually dropped the #defines from psb_intel_reg.h.

PVR: Drop support for kernel versions 2.6.34 and older
There is absolutely no guarantee that the driver would work with kernel
versions 2.6.34 or older, even with the conditional compilation in place,
and the further modifications that will be made to the driver won't take
older kernels into account anyway. Thus explicitly drop support for 2.6.34
and earlier instead of pretending.

pvr: Free export handle only after memory is freed
Export handles are currently freed when the exporter frees it local
mapping of the memory. Next export may (is very likely) to reuse the
handle for different memory.
While process that received the export handle wants to avoid expensive
memory mapping when it already has mapped a matching handle. If the
memory behind a handle changes suddenly process receiving process will
continue use old memory.
Problem can be seen in screen that random client would lose content
because it renders to old memory while display server shows the new
memory in screen.
The fix is to delay the free of the handle until the memory is freed.

PVR: Fix PVR build so that it doesn't get rebuilt every time
Use symlinks instead of copies of the source files, and preserve them using
.PRECIOUS to 1) build the driver so that it doesn't get rebuilt every time,
and 2) produce useful paths in the build log that point to the actual
source files through the symlinks. Add the intermediate symlinks to
.gitignore.
This is a slight improvement to the original hack of building more than one
kernel module from the same sources with different config options and
defines. It should be fixed later, but this makes life easier now.
Also make the Medfield and Moorestown Makefiles as similar to each other as
possible, to make later unification easier.

moorestown/pvr: Enable memory debug only in debug build
Memory debug flags have huge runtime footprint which can be seen
as one of larges CPU users in system. In my QT/demos/declarative/snake
profile cost was about 15% CPU time.
Actual test case is GPU limited so optimization doesn't give fps boost
but it maybe meaningfull optimization for applciation startup and
shutdown times.
Also fixing incorrectly typed DEBUG_LINUX_MEM_AREAS to actually enable
the feature.

Video: optimized udelay usage
1) From Liu, Haiyang: there is a call path psb_setup_fw() -> psb_wait_for_register()
-> udelay(1000), which is not C0 friendly, reduce it to 1
2) export three runtime options for further optimization/tuning
-Export option "cpu_relax" to replace all "udelay" to "cpu_relax" at runtime
-Export option "udelay_multiplier" to multiple the udealy usec with a value (increase)
-Export option "udelay_divider" to divide the udelay usec with a value (decrease)

Video:Fix Topaz D0i3 hang issue.
BZ: 1478
After enalbe Topaz D0i3 manually by "echo 0x2 > /sys/module/medfield_gfx/parameters/topaz_pmpolicy", video encoding performance is very low and the en
coded clip is corruptted. See error message "TOPAZ timeout (probable lockup) detected" in terminal.
This patch fix several potential problems in Topaz save and restore MTX state functions. Save the content of Topaz communication registers before power down Topaz and restore it after resume. Before power down Topaz, poll MMU control register until make sure there is no pending memory request. Reset MVEA twice according to IMG's advice. After transfer firmware to Topaz, kick NULL command to Topaz core 0 and core 1 and wait for its completion. If polling the writeback of NULL commands times out, read back 4 words from command FIFO to recover the state of it.
Inserting NULL commands would cause extra delay of resuming Topaz and reading back 4 words from command FIFO doesn't guarantee successfuly recovery everytime, but it makes video encoding much more stable while enter and exit D0i3. It will be removed after IMG provide a total fix in Topaz firmware.

GFX: use raw_edid on mrst tablet
currently the modeline used on mrst tablet is retrieved from GCT
table in which the vertical refresh rate is about 49 HZ, but it isn't
seem to be the best modeline because the EDID probed from LVDS panel
recommending 60 HZ vrefresh rate.
Also the h/w design on mrst tablet requires i2c0 as the channel for
EDID probe, fixing this by adding DMI_MATCH code for mrst tablet.
Another issue is that the EDID checksum on mrst tablet is bad, which block
driver doing further modeline parse, this maybe a problem of LVDS panel,
add workaround to use raw_edid on mrst tablet.

GFX-Display: Enabled S0i3 for TMD panel.
Now the system could enter and exit S0i3 for several times, with TMD/TPO panel
attached on MDFLD, by the steps:
1. Enable S0i3:
a) echo 12000 > /proc/sys/vm/dirty_writeback_centisecs
b) echo s0i3 > /sys/module/mid_pmu/parameters/s0ix
c) echo 1 >/sys/devices/platform/max3110/adaptive
2. xset dpms force off (or "xset s $TIMEOUT $INTERVAL")
Also fixed the "Fabrice Error" issue when in S0i3 state.

Enlarge GENERAL_MAPPING heap to make sure more apps can run on SGX535 platform simultaneously.
The GENERAL_MAPPING heap is created as shared heap for multi-contexts
to fix one HW issue (BRN_23410). The heap size is set to 128M, which
is not enough for high memory usage under MeeGo Tablet 1280x600 mode.
Now set it to 512M to satisfy UI memory request.

GFX-Display: Fixed glsync tearing issue on MIPI panel.
Tearing happens while running glsync -s b on both MIPI panel with vsync enabled.
The root cause of this issue is that 3D blit happens during write_mem_start command transmission.
Add a fixing to wait for DBI FIFO empty before schedule 3D blit to system frame buffer.
TE interrupt of second MIPI panel was enabled since we need to send out write_mem_start command only when TE interrupt happens.
Known issue:
In dual MIPI clone mode, two MIPI panels share the same system frame buffer and TE interrupts may NOT happen at the same time,
so if one of the TE interrupt handler woke up 3D blit to frame buffer, there would be tearing on the other MIPI panel
if it is sending write_mem_start command

usb/penwell_otg: set charging current limitation to 100mA by default for SDP case
BZ: 38168
This is in order to workaround one issue in low battery level case,
set charging current to 100mA once SDP is detected. Late setting
may cause system shutdown due to low power state.

atomisp: [mt9e013]set frame_valid flag in work queue call back.
BZ: 41629
root cause:
gain control was designed below;
First: control the filter at SOF via work queue.
Next: respond the gain setup request via ioctl from user space.
However work queue service delayed when cpu is heavily-loaded.
This situation happens at 1080 recording.
The work queue call back delayed 12 msec from enqueued at worst.
In this case, control order is broken like below;
First: respond the gain setup request.
Second: control the filter.
In the result, gain is setupped twice during one frame.
solution:
set frame_valid flag in the work queue call back instead receipt SOF signal.
then the gain setup request is suspended when work queue service delayed.

GFX-Display: Added Post2 support for frame buffer flipping.
BZ: 33412
This is 1/3 patches to solve Bug 33412.
Since post() path only supports update display plane surface in
kernel driver, we cannot configure other display plane settings
dynamically from user space.
This patch eanbled frame buffer flipping in Post2() path, and it
enhanced kernel driver to be able to re-config all display plane
registers, so that HWC can adjust display plane configs such as
plane format, z order dynamically.
This patch also increased the number of buffer of display class
so that we can multiple buffers to kernel driver in one flip cmd.

GFX-Display: detach overlay rw ioctrl, gtt map/umap ioctrl from drm global lock.
BZ: 38361
1. Gtt map/unmap ioctrl don't need hold drm global lock. There is already a mm lock
for protecting gtt mm resource.
2. overlay wait vblank function should not block on mode_config lock, that will cause
actual wait time exceed a vblank period.
3. Add a mutex to protect overlay rw ioctrl instead of drm global lock. Because this
ioctrl is only used by overlay, it is not necessary to lock other display registers.
