module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.
It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.

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.

There is no limit to the number of displays that can registered with DSS2. The
current value of MAX_DISPLAYS is 3, set this to 10 so that the 'displays'
member of omap2video_device struct can store more omap_dss_device pointers.
This fixes a crash seen in omap_vout_probe when DSS2 registers for more than 3
displays.

Add support for DSI panels. DSI video mode panels will work directly. For
command mode panels, we will need to trigger updates regularly. This isn't done
by the omap_vout driver currently. It can still be supported if we connect a

Currently, in omap_vout_isr(), if the panel type is DPI, and if we
get either VSYNC or VSYNC2 interrupts, we proceed ahead to set the
current buffers state to VIDEOBUF_DONE and prepare to display the
next frame in the queue.
On OMAP4, because we have 2 LCD managers, the panel type itself is not
sufficient to tell if we have received the correct irq, i.e, we shouldn't
proceed ahead if we get a VSYNC interrupt for LCD2 manager, or a VSYNC2
interrupt for LCD manager.
Fix this by correlating LCD manager to VSYNC interrupt and LCD2 manager
to VSYNC2 interrupt.

The commit 383e4f69879d11c86ebdd38b3356f6d0690fb4cc makes reqbuf prevent
requesting a larger size buffer than what is allocated at kernel boot during
omap_vout_probe.
In omap_vout_buffer_setup callback API, the requested size is compared with
vout->buffer_size, this isn't correct as vout->buffer_size is later set to the
size requested in reqbuf. When the video device is opened the next time, this
check will prevent us to allocate a buffer which is larger than what we requested
the last time.
Don't use vout->buffer_size, always check with the parameters video1_bufsize
or video2_bufsize.

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.

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.

The usecase where, user allocates small size of buffer
through bootargs (video1_bufsize/video2_bufsize) and later from application
tries to set the format which requires larger buffer size, driver doesn't
check for insufficient buffer size and allows application to map extra buffer.
This leads to kernel crash, when user application tries to access memory
beyond the allocation size.
Added check in both mmap and reqbuf call back function,
and return error if the size of the buffer allocated by user through
bootargs is less than the S_FMT size.
