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.

Writeback pipeline receives RGB data from one of the overlays or one of the
overlay managers. If the target color mode is YUV422 or NV12, we need to convert
the RGB pixels to YUV. The scaler in WB then converts it to the target color
mode.
Hence, the color conversion coefficients that need to be programmed are the ones
which convert a RGB24 pixel to YUV444. Program these coefficients for writeback
pipeline.
Rearrange the code a bit to configure different coefficients for overlays and
writeback.

is renamed to buf_width, to give the value of stride the writeback buffer has.

The scalers of overlays and writeback do not have any constraints on downscale
ratio when operating in memory to memory mode.
This is because in memory to memory mode, we aren't connected to a display which
needs data output at the rate of pixel clock. The scalers can perform as much
downscaling as needed, the rate at which the scaler outputs is adjusted
accordingly.
Relax constraints related to downscaling based on whether the input overlays are
connected to writeback in memory to memory mode. We pass a mem_to_mem boolean
parameter to dispc_ovl_setup() from APPLY. This is currently set to false, this
will later be configured to the correct value based on whether the overlay is
connected to writeback or not. Do the same later for writeback when writeback is
configured.
In the scaling calculation code, we calculate the minimum amount of core clock we
need to achieve the required downscaling. If we are in memory to memory mode, we
set this to a very small value(1 in this case), this value would always be
lesser than the actual DISPC core clock value, and hence the scaling checks
would succeed.
We take care that pixel clock isn't calculated for writeback and the overlays
connected to it when in memory to memory mode. A pixel clock in such cases
doesn't make sense.

dispc_ovl_setup_common() is to be used by both overlays and writeback. We pass
channel out to figure out what manager the overlay is connected to, to determine
the pixel clock rate. This is used to decide the scaling limitations for that
overlay.
writeback doesn't have a channel out, it has a channel in field which tells
where writeback gets its input from. These are 2 different fields, and this
prevents us reusing the overlay configuration code for writeback.
To overcome this, we now pass omap_plane to overlay related functions rather
than passing channel out. We create helper functions which can derive pclk/lclk
from the omap_plane id.

These functions will be used for writeback later, and the caps will help in
deciding if they are to be used for writeback or not. This allows reuse of
overlay caps for writeback.

The current OMAPDSS design contains 3 software entities: Overlays, Managers and
Devices. These map to pipelines, overlay managers and the panels respectively in
hardware. One or more overlays connect to a manager to represent a composition,
the manager connects to a device(generally a display) to display the content.
The part of DSS hardware which isn't represented by any of the above entities
are interfaces/outputs that connect to an overlay manager, i.e blocks like DSI,
HDMI, VENC and so on. Currently, an overlay manager directly connects to the
display, and the output to which it is actually connected is ignored. The panel
driver of the display is responsible of calling output specific functions to
configure the output.
Adding outputs as a new software entity gives us the following benefits:
- Have exact information on the possible connections between managers and
outputs: A manager can't connect to each and every output, there only limited
hardware links between a manager's video port and some of the outputs.
- Remove hacks related to connecting managers and devices: Currently, default
links between managers and devices are set in a not so clean way. Matching is
done via comparing the device type, and the display types supported by the
manager. This isn't sufficient to establish all the possible links between
managers, outputs and devices in hardware.
- Make panel drivers more generic: The DSS panel drivers currently call
interface/output specific functions to configure the hardware IP. When making
these calls, the driver isn't actually aware of the underlying output. The
output driver extracts information from the panel's omap_dss_device pointer
to figure out which interface it is connected to, and then configures the
corresponding output block. An example of this is when a DSI panel calls
dsi functions, the dsi driver figures out whether the panel is connected
to DSI1 or DSI2. This isn't correct, and having output as entities will
give the panel driver the exact information on which output to configure.
Having outputs also gives the opportunity to make panel drivers generic
across different platforms/SoCs, this is achieved as omap specific output
calls can be replaced by ops of a particular output type.
- Have more complex connections between managers, outputs and devices: OMAPDSS
currently doesn't support use cases like 2 outputs connect to a single
device. This can be achieved by extending properties of outputs to connect to
more managers or devices.
- Represent writeback as an output: The writeback pipeline fits well in OMAPDSS
as compared to overlays, managers or devices.
Add a new struct to represent outputs. An output struct holds pointers to the
manager and device structs to which it is connected. Add functions which can
register/unregister an output, or look for one. Create an enum which represent
each output instance.

The functions dss_mgr_wait_for_go() and dss_mgr_wait_for_go_ovl() check if there
is an enabled display connected to the manager before trying to see the state of
the GO bit.
The checks related to the display can be replaced by checking the state of the
manager, i.e, whether the manager is enabled or not. This makes more sense than
checking with the connected display as the GO bit behaviour is more connected
with the manager state rather than the display state. A GO bit can only be set
if the manager is enabled. If a manager isn't enabled, we can safely assume that
the GO bit is not set.
