Setting overlay's output channel is currently handled at the same time
as other overlay attributes. This is not right, as the normal attributes
should only affect one overlay and manager, but changing the channel
affects two managers.This patch moves the channel field into the "extra_info" set, handled
together with enabled-status.Signed-off-by: Tomi Valkeinen

Overlays are currently enabled and disabled with a boolean in the struct
omap_overlay_info. The overlay info is set with ovl->set_overlay_info(),
and made into use with mgr->apply().This doesn't work properly, as the enable/disable status may affect also
other overlays, for example when using fifo-merge. Thus the enabling and
disabling of the overlay needs to be done outside the normal overlay
configuration.This patch achieves that by doing the following things:
1) Add function pointers to struct omap_overlay: enable(), disable() and
is_enabled(). These are used to do the obvious. The functions may block.2) Move the "enabled" field from struct omap_overlay to ovl_priv_data.
3) Add a new route for settings to be applied to the HW, called
"extra_info". The status of the normal info and extra_info are tracked
separately.The point here is to allow the normal info to be changed and
applied in non-blocking matter, whereas the extra_info can only be
changed when holding the mutex. This makes it possible to, for example,
set the overlay enable flag, apply it, and wait until the HW has taken
the flag into use.This is not possible if the enable flag would be in the normal info, as
a new value for the flag could be set at any time from the users of
omapdss.Signed-off-by: Tomi Valkeinen

struct omap_overlay_manager contains "enabled"-field, used to track if

The current code uses dsi_video_mode_enable/disable functions to
enable/disable DISPC output for video mode displays. For command mode
displays we have no notion in the DISPC side of whether the panel is
enabled, except when a dss_mgr_start_update() call is made.However, to properly maintain the DISPC state in apply.c, we need to
know if a manager used for a manual update display is currently in use.This patch achieves that by changing dsi_video_mode_enable/disable to
dsi_enable/disable_video_output, which is called by both video and
command mode displays. For video mode displays it starts the actual
pixel stream, as it did before. For command mode displays it doesn't do
anything else than mark that the manager is currently in use.Signed-off-by: Tomi Valkeinen

Current way of handling overlay-manager links is a bit strange: each
manager has a static array, containing pointers to all the overlays
(even those used by other managers). The overlays contain a pointer to
the manager being used.This patch makes the system a bit saner: each manager has a linked list
of overlays, and only the overlays linked to that manager are in the
list.Signed-off-by: Tomi Valkeinen
-
Overlay managers are stored in a linked list. There's no need for this
list, as an array would do just as fine.This patch changes the code to use an array for overlay managers.

omap_overlay_manager struct contains enable() and disable() functions.
However, these are only meant to be used from inside omapdss, and thus
it's bad to expose the functions.This patch adds dss_mgr_enable() and dss_mgr_disable() functions to
apply.c, which handle enabling and disabling the output.Signed-off-by: Tomi Valkeinen

Partial update for manual update displays has never worked quite well:
* The HW has limitations on the update area, and the x and width need to
be even.
* Showing a part of a scaled overlay causes artifacts.
* Makes the management of dispc very complexConsidering the above points and the fact that partial update is not
used anywhere, this and the following patches remove the partial update
support. This will greatly simplify the following re-write of the apply
mechanism to get proper locking and additional features like fifo-merge.This patch removes the partial update from the dsi.c.

This patch adds a custom DSS reset function used on OMAPs from OMAP2
forward.The function doesn't actually do a reset, it only waits for the reset to
complete. The reason for this is that on OMAP4 there is no possibility
to do a SW reset, and on OMAP2/3 doing a SW reset for dss_core resets
all the other DSS modules also, thus breaking the HWMOD model where
every DSS module is handled independently.This fixes the problem with DSS reset on OMAP4, caused by the fact that
because there's no SW reset for dss_core on OMAP4, the HWMOD framework
doesn't try to reset dss_core and thus the DSS clocks were never enabled
at the same time. This causes causes the HWMOD reset to fail for
dss_dispc and dss_rfbi.The common reset function will also allow us to fix another problem in
the future: before doing a reset we need to disable DSS outputs, which
are in some cases enabled by the bootloader, as otherwise DSS HW seems
to get more or less stuck, requiring a power reset to recover.Signed-off-by: Tomi Valkeinen

Add zorder support on OMAP4, this feature allows deciding the visibility order
of the overlays based on the zorder value provided as an overlay info parameter
or a sysfs attribute of the overlay object.Use the overlay cap OMAP_DSS_OVL_CAP_ZORDER to determine whether zorder is
supported for the overlay or not. Use dss feature FEAT_ALPHA_FREE_ZORDER
if the caps are not available.Ensure that all overlays that are enabled and connected to the same manager
have different zorders. Swapping zorders of 2 enabled overlays currently
requires disabling one of the overlays.Signed-off-by: Archit Taneja

On OMAP3, in order to enable alpha blending for LCD and TV managers, we needed
to set LCDALPHABLENDERENABLE/TVALPHABLENDERENABLE bits in DISPC_CONFIG. On
OMAP4, alpha blending is always enabled by default, if the above bits are set,
we switch to an OMAP3 compatibility mode where the zorder values in the pipeline
attribute registers are ignored and a fixed priority is configured.Rename the manager_info member "alpha_enabled" to "partial_alpha_enabled" for
more clarity. Introduce two dss_features FEAT_ALPHA_FIXED_ZORDER and
FEAT_ALPHA_FREE_ZORDER which represent OMAP3-alpha compatibility mode and OMAP4
alpha mode respectively. Introduce an overlay cap for ZORDER. The DSS2 user is
expected to check for the ZORDER cap, if an overlay doesn't have this cap, the
user is expected to set the parameter partial_alpha_enabled. If the overlay has
ZORDER cap, the DSS2 user can assume that alpha blending is already enabled.Don't support OMAP3 compatibility mode for now. Trying to read/write to
alpha_blending_enabled sysfs attribute issues a warning for OMAP4 and does not
set the LCDALPHABLENDERENABLE/TVALPHABLENDERENABLE bits.Change alpha_enabled to partial_alpha_enabled in the omap_vout driver. Use
overlay cap "OMAP_DSS_OVL_CAP_GLOBAL_ALPHA" to check if overlay supports alpha
blending or not. Replace this with checks for VIDEO1 pipeline.Cc: linux-media@vger.kernel.org

overlay_info struct, used to configure overlays, currently includes both
physical and virtual addresses for the pixels. The vaddr was added to
support more exotic configurations where CPU would be used to update a
display, but it is not currently used and there has been no interest in
the feature. Using CPU to update a screen is also less interesting now
that OMAP4 has two LCD outputs.This patch removes the vaddr field, and modifies the users of omapdss
accordingly. This makes the use of omapdss a bit simpler, as the user
doesn't need to think if it needs to give the vaddr.Signed-off-by: Tomi Valkeinen

This is a driver for N800's display, ported from the old omapfb. This is
a slightly lighter version of the driver as not all features of the old
driver can be ported without big changes to DSS2, and also because some
of the HW features used in the old driver are unclear (e.g. the power
management part).That said, the new driver works fine for basic use.
Architecturally the driver is not as neat as it could be. N800's display
HW consists of a display buffer chip and a panel, and ideally they would
be represented by separate, independent drivers. This is not currently
possible, and this driver contains both buffer chip and panel driver.Signed-off-by: Tomi Valkeinen

Taal panel driver supports two kinds of backlight control: 1) using DSI
commands sent to the panel to control the backlight, 2) calling function
pointers going to the board file to control the backlight.The second option is a bit hacky, and will no longer be needed when the
PWM driver supports the backlight features. After that we can use the
standard PWM backlight driver.This patch removes the second backlight control mechanism, and adds a
boolean field, use_dsi_backlight, to nokia_dsi_panel_data which the
board file can use to inform whether the panel driver should use DSI
commands to control the backlight.Signed-off-by: Tomi Valkeinen

We have currently panel-generic-dpi driver, which is a combined driver
for dummy panels and also for DVI output.The aim is to split the panel-generic-dpi into two, one for fixed size
dummy panels connected via DPI, and the other (this) for variable

chip connected to DPI output).Original i2c code by: Ricardo Salveti de Araujo
