The printk in DSSDBG function definition is replaced with dynamic debug enabled
pr_debug(). The use of dynamic debugging provides more flexibility as each debug
statement can be enabled or disabled dynamically on basis of source filename,
line number, module name etc., by writing to a control file in debugfs
filesystem. For better understanding please refer to
Documentation/dynamic-debug-howto.txt.
The DSSDBGF() differs from DSSDBG() by providing function name. However,
function name, line number, module name and thread ID can be printed through
dynamic debug by setting appropriate flags 'f','l','m' and 't' in the debugfs
control file. So, DSSDBGF instances are replaced with DSSDBG.

Add output structs to output driver's private data. Register output instances by
having an init function in the probes of the platform device drivers for
different outputs. The *_init_output for each output registers the output and
fill up the output's plaform device, type and id fields. The *_uninit_output
functions unregister the output.
In the probe of each interface driver, the output entities are initialized
before the *_probe_pdata() functions intentionally. This is done to ensure that
the output entity is prepared before the panels connected to the output are
registered. We need the output entities to be ready because OMAPDSS will try

OMAP5 DSI PHY has DCC (Duty Cycle Corrector) block, and by default DCC
is enabled and thus the PLL clock is divided by 2 to get the DSI DDR
clk. This divider has been 4 for all previous OMAPs, and changing it
needs some reorganization of the code. The DCC can be disabled, and in
that case the divider is back to the old 4.
This patch adds dss feature for the DCC, and adds code to always disable

We currently create omap_dss_devices statically in board files, and use
those devices directly in the omapdss driver. This model prevents us
from having the platform data (which the dssdevs in board files
practically are) as read-only, and it's also different than what we will
use with device tree.
This patch changes the model to be in line with DT model: we allocate
the dssdevs dynamically, and initialize them according to the data in
the board file's dssdev (basically we memcopy the dssdev fields).
The allocation and registration is done in the following steps in the
output drivers:
- Use dss_alloc_and_init_device to allocate and initialize the device.
The function uses kalloc and device_initialize to accomplish this.
- Call dss_copy_device_pdata to copy the data from the board file's
dssdev
- Use dss_add_device to register the device.

We have boards with multiple panel devices connected to the same
physical output, of which only one panel can be enabled at one time.
Examples of these are Overo, where you can use different daughter boards
that have different LCDs, and 3430SDP which has an LCD and a DVI output
and a physical switch to select the active display.
These are supported by omapdss so that we add all the possible display
devices at probe, but the displays are inactive until somebody enables
one. At this point the panel driver starts using the DSS, thus reserving
the physcal resource and excluding the other panels.
This is problematic:
- Panel drivers can't allocate their resources properly at probe(),
because the resources can be shared with other panels. Thus they can
be only reserved at enable time.
- Managing this in omapdss is confusing. It's not natural to have
child devices, which may not even exist (for example, a daughterboard
that is not connected).
Only some boards have multiple displays per output, and of those, only
very few have possibility of switching the display during runtime.
Because of the above points:
- We don't want to make omapdss and all the panel drivers more complex
just because some boards have complex setups.
- Only few boards support runtime switching, and afaik even then it's
not required. So we don't need to support runtime switching.
Thus we'll change to a model where we will have only one display device
per output and this cannot be (currently) changed at runtime. We'll
still have the possibility to select the display from multiple options
during boot with the default display option.
This patch accomplishes the above by changing how the output drivers
register the display device. Instead of registering all the devices
given from the board file, we'll only register one. If the default
display option is set, the output driver selects that display from its
displays. If the default display is not set, or the default display is
not one of the output's displays, the output driver selects the first
display.

get the number from, and it doesn't work very well even with non-DT as

Currently the way to configure clocks related to DSI (both DSI and DISPC
clocks) happens via omapdss platform data. The reason for this is that
configuring the DSS clocks is a very complex problem, and it's
impossible for the SW to know requirements about things like
interference.
However, for general cases it should be fine to calculate the dividers
for clocks in the SW. The calculated clocks are probably not perfect,
but should work.
This patch adds support to calculate the dividers when using DSI command
mode panels. The panel gives the required DDR clock rate and LP clock
rate, and the DSI driver configures itself and DISPC accordingly.
This patch is somewhat ugly, though. The code does its job by modifying
the platform data where the clock dividers would be if the board file
gave them. This is not how it's going to be in the future, but allows us
to have quite simple patch and keep the backward compatibility.
It also allows the developer to still give the exact dividers from the
board file when there's need for that, as long as the panel driver does
not override them.
There are also other areas for improvement. For example, it would be
better if the panel driver could ask for a DSI clock in a certain range,
as, at least command mode panels, the panel can work fine with many
different clock speeds.
While the patch is not perfect, it allows us to remove the hardcoded
clock dividers from the board file, making it easier to bring up a new
panel and to use device tree from omapdss.

For DSI operation in videomode, DISPC logic levels for the signals HSYNC, VSYNC

DSI supports interleaving of command mode packets during the HSA, HFP, HBP and
BLLP blanking intervals in a video mode stream. This is useful as a user may
want to read or change the configuration of a panel without stopping the video
stream.
On OMAP DSI, we can queue HS or LP command mode packets in the TX FIFO, and
the DSI HW takes care of interleaving this data during the one of the blanking
intervals. The DSI HW needs to be programmed with the maximum amount of data
that can be interleaved in a particular blanking period. A blanking period
cannot be used to send command mode data for it's complete duration, there is
some amount of time required for the DSI data and clock lanes to transition
to the desired LP or HS state.
Based on the state of the lanes at the beginning and end of the blanking period,
we have different scenarios, with each scenario having a different value of time
required to transition to HS or LP. Refer to the section 'Interleaving Mode' in
OMAP TRM for more info on the scenarios and the equations to calculate the time
required for HS or LP transitions.
We use the scenarios which takes the maximum time for HS or LP transition, this
gives us the minimum amount of time that can be used to interleave command mode
data. The amount of data that can be sent during this minimum time is calculated
for command mode packets both in LP and HS. These are written to the registers
DSI_VM_TIMING4 to DSI_VM_TIMING6.
The calculations don't take into account the time required of transmitting BTA
when doing a DSI read, or verifying if a DSI write went through correctly. Until
these latencies aren't considered, the behaviour of DSI is unpredictable when
a BTA is interleaved during a blanking period. Enhancement of these calculations
is a TODO item.
The calculations are derived from DSI parameter calculation tools written by

Currently the higher level omapdss platform driver gets the list of
displays in its platform data, and uses that list to create the
omap_dss_device for each display.
With DT, the logical way to do the above is to list the displays under
each individual output, i.e. we'd have "dpi" node, under which we would
have the display that uses DPI. In other words, each output driver
handles the displays that use that particular output.
To make the current code ready for DT, this patch modifies the output
drivers so that each of them creates the display devices which use that
output. However, instead of changing the platform data to suit this
method, each output driver is passed the full list of displays, and the
drivers pick the displays that are meant for them. This allows us to
keep the old platform data, and thus we avoid the need to change the
board files.
