When doing a manual update in dss_mgr_start_update, we clear the shadow dirty
flags. Although there isn't any harm in clearing them. The need to clear them
out here should never arrive.
When applying configurations for a manual update manager, we never do any
register writes, i.e, calls to dss_mgr_write_regs and dss_mgr_write_regs_extra
never happen while applying. We do all these writes only when we call
dss_mgr_start_update. Hence, there is never a time when the shadow registers
are dirty.
Remove the call to mg_clear_shadow_dirty.

An overlay's channel out field isn't a shadow register. The TRM says that it's
taken into effect immediately. This understanding was missing and channel out
was treated as a shadow parameter, and in overlay's private data as extra info.
Program channel out bits directly in dss_ovl_set_manager(). In order to do this
safely, we need to be totally sure that the overlay is disabled in hardware. For
auto update managers, we can assume that the overlay was truly disabled at
dss_ovl_unset_manager() through the wait_pending_extra_info_updates() call.
However, when unsetting manager for an overlay that was previously connected to
a manager in manual update, we can't be sure if the overlay is truly disabled.
That is, op->enabled might not reflect the actual state of the overlay in
hardware. The older manager may require a manual update transfer to truly
disable the overlay. We expect the user of OMAPDSS to take care of this, in
OMAPDSS, we make sure that an overlay's manager isn't unset if there if
extra_info is still dirty for that overlay.
The wrong understanding of channel out bits also explains the reason why we see
sync lost when changing an overlay's manager which was previously connected to a
manual update manager. The following sequence of events caused this:
- When we disable the overlay, no register writes are actually done since the
manager is manual update, op->enabled is set to false, and the
extra_info_dirty flag is set. However, in hardware, the overlay is still
enabled in both shadow and working registers.
- When we unset the manager, the software just configures the overlay's manager
to point to NULL.
- When we set the overlay to a new manager(which is in auto update) through
dss_ovl_set_manager, the check for op->enabled passes, the channel field in
extra info is set to the new manager. When we do an apply on this manager,
the new channel out field is set in the hardware immediately, and since the
overlay enable bit is still set in hardware, the new manager sees that the
overlay is enabled, and tries to retrieve pixels from it, this leads to sync
lost as it might be in the middle of processing a frame when we set the
channel out bit.
The solution to this was to ensure that user space does another update after
disabling the overlay, this actually worked because the overlay was now truly
disabled, and an immediate write to channel out didn't impact since the manager
saw the new overlay as disabled, and doesn't try to retrieve pixels from it.
Remove channel as an extra_info field. Make dss_ovl_unset_manager more strict
about the overlay being disabled when detaching the manager. For overlays
connected to a manual update manager, unset_manager fails if we need another
update to disable the overlay.
We still need to a manual update to ensure the overlay is disabled to get change
the overlay's manager. We could work on doing a dummy update by using DISPC's
capability to gate the different video port signals. This is left for later.
Remove the comment about the sync lost issue.

writeback
When calculating row and pixel increments for graphics and video pipes, we need
to consider the dimensions of the input frame to know how to read from the
buffer. Hence, we need to calculate these parameters from the input to the
pipeline.
For writeback, the row and pixel increments need to be calculated based on the
output of the writeback pipeline, i.e, the dimensions of the frame after
scaling. Ensure that dispc driver uses values of out_width and out_height when
calling calc_dma/calc_tiler_rotation_offset.
For graphics and video pipes, the original code passed the original height as
frame_height to calc_dma_rotation_offset, and not the predecimated height. This
is left as it is for now. We need to figure out why pre decimated height isn't
needed.

dispc_ovl_calc_scaling_44xx() doesn't work correctly for writeback. There are
two issues with it:
- the function tries to calculate pixel clock for the input plane using
dispc_plane_pclk_rate(), calling this with writeback as input plane results in
a BUG(), this function shouldn't be called for writeback at all. Fix this by
calculating pixel clock only when we are not in mem to mem mode.
- the maximum input_width is the product of the downscale ratio supported and
the and the given output_width. This was calculated incorrectly by dividing
output_width with maxdownscale. Fix this.

Normally the omapdss driver gets the regulators using the regulator
names assigned for omapdss. However, in an effort to get a minimal DSS
support for DT enabled kernel on selected boards, we will add omapdss
devices and platform data the old way even for DT kernel. This causes
the problem that omapdss cannot find the regulators using omapdss's
regulator names.
This patch creates a temporary workaround for DSI and HDMI by trying to
get the regulators also using native OMAP4 regulator names.

Creating the accessory devices, such as audio, from the HDMI driver
allows to regard HDMI as a single entity with audio an display
functionality. This intends to follow the design of drivers such
as MFD, in which a single entity handles the creation of the accessory
devices. Such devices are then used by domain-specific drivers; audio in
this case.
Also, this is in line with the DT implementation of HDMI, in which we will
have a single node to describe this feature of the OMAP SoC.

dss.c currently exposes functions to configure the dispc source clock
and lcd source clock. There are configured separately from the output
drivers.
However, there is no safe way for the output drivers to handle dispc
clock, as it's shared between the outputs. Thus, if, say, the DSI driver
sets up DSI PLL and configures both the dispc and lcd clock sources to
that DSI PLL, the resulting dispc clock could be too low for, say, HDMI.
Thus the output drivers should really only be concerned about the lcd
clock, which is what the output drivers actually use. There's lot to do
to clean up the dss clock handling, but this patch takes one step
forward and removes the use of dss_select_dispc_clk_source() from the
output drivers.
After this patch, the output drivers only configure the lcd source
clock. On omap4+ the dispc src clock is never changed from the default
PRCM source. On omap3, where the dispc and lcd clocks are actually the
same, setting the lcd clock source sets the dispc clock source.

We don't currently set the dss fck when starting up. This is not a
problem, as we setup the fck later when configuring the pixel clocks. Or
this is how it was for omap2, for the rest of the omaps this may not be
so.
For DSI, HDMI and also for DPI when using DSI PLL, we don't need to
change the dss fck, and thus it may be left unconfigured. Usually the
dss fck is already setup fine by default, but we can't trust this.
This patch sets the dss fck to maximum at probe time.

The DSI PLL and HSDivider can be used to generate the pixel clock for
LCD overlay manager, which then goes to DPI output. On the DPI output
pin the voltage of the signal is shifted from the OMAP's internal
minimal voltage to 1.8V range. The shifting is not instant, and the
higher the clock frequency, the less time there is to shift the signal
to nominal voltage.
If the HSDivider's divider is greater than one and odd, the resulting
pixel clock does not have 50% duty cycle. For example, with a divider of
3, the duty cycle is 33%.
When combining high frequency (in the area of 140MHz+) and non-50% duty
cycle, it has been observed the the shifter does not have enough time to
shift the voltage enough, and this leads to bad signal which is rejected
by monitors.
As a workaround this patch makes the divider calculation skip all odd
dividers when the required pixel clock is over 100MHz. The limit of
100MHz is a guesstimate.

DPI may use DSI PLL, so it depends on DSI. However, currently DPI driver
is added first, which causes DPI initialization to fail when it tries to
get the DSI PLL.
This patch changes the init order to fix this.
A better solution would be to separate DSI PLL and DSI drivers. They
have dependencies, though, but we could still have DSI PLL as an
independent entity that we could initialize before any of the output
drivers.
