We could set rb swap in two modules: DMA controler input part and
dsi interface output part.
DMA input part is based on pix_fmt to set rbswap, dsi output interface
part will set rbswap based on platform dsi_rbswap configuration.
This patch include below change and enhancement:
1) The input format which support rbswap is based on RGB format,
eg. RGB565 indicates the source data in memory is that Red is [15~11],
Green is [10~5], Blue is [4:0], Red is MSB, Blue is LSB, but for the
display dma input default setting(rbswap = 0), it only support Blue
is [15~11], Green is [10~5], Red is [4:0], Red is LSB, Blue is MSB,
so for this format(RGB565), display controller need to set rbswap
= 1 and it can support the MSB/LSB correctly.
BGR/YUV format will not set it in mmp display driver.
2) The dsi output part of rbswap is depend on dsi_rbswap which is
defined in specific platfrom. For output dsi interface, it has this
feature to do rbswap again if it needs specifc byte sequence of RGB
byte for DSI panel.
eg. If display content is set RGB565 in memory and DMA input part set
rbswap in driver to support Red as MSB , Blue LSB, but dsi panel only
support Red as LSB, Blue as MSB, then it can use this feature.
If there is no this requirement of panel, this dsi output part is not
needed.

Use the already existing pm_cap variable in struct pci_dev for
determining the power management offset. This saves the driver from
having to keep track of an extra variable. Also, use the pci_power_t
value instead of always using the raw value for PCI_D2.

We have a bug with omapdrm, where omapdrm calls dispc's pm_runtime
function in atomic context, and dispc's pm_runtime is not marked as
irq_safe:
BUG: sleeping function called from invalid context at drivers/base/power/runtime.c:952
Dispc's runtime PM callbacks are irq safe, so we can just set the
irq_safe flag to fix the issue.
However, in the long term, I'd rather have omapdrm manage the runtime PM
calls in a better way. Calling get/put for every small operation that
touches the dispc registers is very inefficient. It'd be better and
cleaner to have clear "in-use" and "not-in-use" states for dispc, so
that we don't need to do register context restore for small operations,
only to turn dispc off right afterwards.

While using HDMI connector driver with sil9022 encoder
came across issue where connector driver is probed first.
This resulted in error. A deffered probe solved this.
Most connector drivers need a encoder driver as their
video source. This patch ensures we do a probe defferal
if video source is not present for connector drivers.

This reverts the Linux for Workgroups thing. And no, before somebody
asks, we're not doing Linux95. Not for a few years, at least.
Sure, the flag added some color to the logo, and could have remained as
a testament to my leet gimp skills. But no. And I'll do this early, to
avoid the chance of forgetting when I'm doing the actual rc1 release on

Board updates for 3.12. Again, a bit of domain overlap with SoC and DT branches,
but most of this is around legacy code and board support. We've found that
platform maintainers have a hard time separating all of these out and might
move towards fewer branches for next release.
- Removal of a number of Marvell Kirkwood board files, since contents
is now common and mostly configured via DT.
- Device-tree updates for Marvell Dove, including irqchip and clocksource
setup.
- Defconfig updates. Gotta go somewhere. One new one for Renesas Lager.
- New backlight drivers for backlights used on Renesas shmobile platforms.
- Removal of Renesas leds driver.

This branch contains code cleanups, moves and removals for 3.12.
There's a large number of various cleanups, and a nice net removal of
13500 lines of code.
Highlights worth mentioning are:
- A series of patches from Stephen Boyd removing the ARM local timer API.
- Move of Qualcomm MSM IOMMU code to drivers/iommu.
- Samsung PWM driver cleanups from Tomasz Figa, removing legacy PWM driver
and switching over to the drivers/pwm one.
- Removal of some unusued auto-generated headers for OMAP2+ (PRM/CM).
There's also a move of a header file out of include/linux/i2c/ to
platform_data, where it really belongs. It touches mostly ARM platform
code for include changes so we took it through our tree.

In the old panel device model we had omap_dss_output entities,
representing the encoders in the DSS block. This entity had "device"
field, which pointed to the panel that was using the omap_dss_output.
With the new panel device model, the omap_dss_output is integrated into
omap_dss_device, which now represents a "display entity". Thus the "device"
field, now in omap_dss_device, points to the next entity in the display
entity-chain.
This patch renames the "device" field to "dst", which much better tells
what the field points to.

In the old panel device model we had "outputs", which were the encoders
inside OMAP DSS block, and panel devices (omap_dss_device). The panel
devices had a reference to the source of the video data, i.e. reference
to an "output", in a field named "output".
That was somewhat confusing even in the old panel device model, but even
more so with the panel device model where we can have longer chains of
display entities.

LCDC IP has a clock divider to adjust pixel clock, this limits pixel
clock range to fck/255 - fck/2(fck - rate of input clock to LCDC IP).
In the case of AM335x, where this IP is present, default fck is not
sufficient to provide normal pixel clock rates, hence rendering this
driver unusable on AM335x.
If input clock too is configurable, allowable range of pixel clock
would increase. Here initially it is checked whether with present fck,
divider in IP could be configured to obtain required rate, if not,
fck is adjusted. This makes it usable on AM335x.
Note:
Another solution would be to model an inherited basic clock divider of
CCF, an advantage would be a better possible resolution for pixel clk.
And trying to instantiate a CCF clock would mean that to be consistent,
3 bits being turned on to enable clocks of LCDC IP would have to be
modeled as gate clocks. Now that would bring in a total of 4 clocks,
including necessity to create a new inherited divider clock, and that
mean a branch of clock tree would be present in LCDC driver. This
would add complexity to LCDC driver bringing in considerable amount
of clock handling code, and this would not bring in much advantage
for existing use cases other than providing a higher resolution of
pixel clock. And existing use cases work without relying on clock
modeling. Another fact is that out of the two platform's using this
driver DaVinci is not yet converted to CCF. In future if higher
resolution of pixel clock is required, and probably after DaVinci is
CCF'ed, modeling clock nodes inside driver may be considered.

The interrupt handler explicitly has code that handles the sync lost
interrupt. However the sync lost interrupt is never actually being
enabled in the LCD controller, therefore this interrupt code path is not
being exercised. This fix simply enables the generation of the sync

appropriately by the interrupt handler.

ti_hdmi_4xxx_basic_configure() is supposed to initialize the AVI

takes a copy of the infoframe from the ip_data, and then goes on
initializing that copy. The initialized data is never copied back to the

we don't use the advanced features offered by the AVI infoframe.

fbdev provides framebuffer hotplugging, hence, we need to allow fbcon to
unbind from framebuffers. Unfortunately, fbcon_fb_unbind() cannot unbind
from the last framebuffer, unless console-unbinding is supported.
Fixing fbcon_unbind() to return 0 caused some horrible NULL-derefs in the
VT layer and I couldn't figure out why. Hence, lets just require
console-unbinding so fbdev hotplugging works with fbcon.

Both information is used by remove_conflicting_framebuffers() to remove a
fbdev device whenever a real driver is loaded. This is used heavily on x86
for VGA/vesa/EFI framebuffers, but is also of great use for all other
systems.

If we create proper platform-devices in x86 boot-code, we can use simplefb
for VBE or EFI framebuffers, too. However, there is normally no OF support
so we introduce a platform_data object so x86 boot-code can pass the
parameters via plain old platform-data.
This also removes the OF dependency as it is not needed. The headers
provide proper dummies for the case OF is disabled.
Furthermore, we move the FORMAT-definitions to the common platform header
so initialization code can use it to transform "struct screen_info" to
the right format-name.

For a combination of 18bit LCD data bus width and a color
mode of 32bpp, the driver was setting the color mapping to
rgb666, which is wrong, as the color in memory realy has an
rgb888 layout.
This patch also removes the setting of flag CTRL_DF24 that
makes the driver dimiss the upper 2 bits when handling 32/24bpp
colors in a diplay with 18bit data bus width. This flag made
true color images display wrong in such configurations.
Finally, the color mapping rgb666 has also been removed as nobody
is using it and high level applications like Qt5 cannot work
with it either.
