manager_cache_data is not a suitable name for the struct. It is more of
a private data for the manager.
Rename the struct to mgr_priv_data, and add a function,
get_mgr_priv(mgr), to get a pointer to the data.

overlay_cache_data is not a suitable name for the struct. It is more of
a private data for the overlay.
Rename the struct to ovl_priv_data, and add a function,
get_ovl_priv(ovl), to get a pointer to the data.

Make configure_overlay() and configure_manager() take overlay/manager
pointer as an argument, instead of the ovl/mgr id. This will be useful
with the future patches.
Also rename the functions to be a bit more informative:
dss_ovl_write_regs, dss_mgr_write_regs, dss_write_regs.

Use dispc_mgr_get_vsync_irq() to get the interrupt numbers for vsync,
instead of hardcoding the values depending on the display type.

Create separate functions for the vsync isr register/unregister code for
cleaner code.

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.

dss_mgr_start_update() has a loop, of which sole purpose is to find the
manager used for this update. The whole loop is extra, as we already
know the manager.
Remove the loop.

There's no need to register the vsync ISR and configure the hardware if
the overlay manager is disabled, so this patch adds a check for disabled
managers to the omap_dss_mgr_apply() function.

The mechanism to cache manager and overlay settings and configure them
into the HW registers in VSYNC is meant only for auto-update displays,
as it doesn't make sense (and doesn't work) for manual-update displays.
This patchs adds a check so that we skip the above for manual update
displays.

Add "enabled" field to struct omap_overlay_manager, which tells if the
output is enabled or not. This will be used in apply.c in the following
patches.

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.

Create a new file, apply.c, and move code about handling the
apply-mechanism and configuration of the managers and overlays from
manager.c to apply.c.
Not all related code is moved in this patch, but only the core
apply/configure functions. The later patches move rest of the code from
overlay.c and manager.c, adding necessary locking at the same time.
