There doesn't seem to be any reason for that, and additionally the soon-to-be-merged patch "ARM: OMAP: omap_device: remove omap_device_parent" will break omapdss initialization with the current registration model.

| * | | | OMAPDSS: APPLY: fix clearing shadow dirty flag with manual updateTomi Valkeinen2012-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the shadow-dirty flags for manual update displays is cleared in the apply_irq_handler when an update has finished.

The call to extra_info_update_ongoing() should really be inside spinlock, but that's a bit heavy just for verification. Rather than that, check the return value of the wait_for_completion_timeout() and print an error if it has timeouted or returned an error. Even better would be to return the error value and act on it in the callers of wait_pending_extra_info_updates. However, it's not clear what the callers should do in case of an error, as the error should only happen if there's a bug in the driver or the HW. So we'll just print the warning for now.

Also, devices that do not support the MCLK, use the TMDS clock directly by leaving ACR_CTRL[2] set to 0. The MLCK clock divisor, mclk_mode, is configured only if MLCK is used. Such configuration is no longer related to the CTS mode as in some silicon revisions CTS SW-mode is used along with the MCLK.

This is done mainly in four functions: mgr_enable/disable and ovl_enable/disable. These are the functions where overlays are taken into and out of active use. The process to enable and disable fifo-merge is not simple. We need to do it in steps, waiting in between for certain settings to be taken into use, and continuing after that. The reason for this is that fifo-merge is a common thing for all managers/overlays, and its use must be synchronized. As an example, when we disable an overlay, we first set the overlay as disabled, then wait until the overlay is actually disabled in the HW, and only after that we may re-configure the fifos, possibly taking fifo-merge into use.

These are similar to the other info/dirty flags in ovl_priv_data and ovl_mgr_data, but fifo merge is a common attribute to all managers and thus outside the ovl_mgr_data. The fifo-merge field is used in the dss_write_regs_common, which handles writing the register. dss_apply_fifo_merge() can be used to set/unset the fifo merge field in the dss_data.

The current kernel doesn't configure fifo sizes yet, and so the code doesn't need to block to function (from omapdss driver's perspective). However, for the users of omapdss a non-blocking ovl->disable is confusing, because they don't know when the memory area is not used any more. Furthermore, when the fifo size configuration is added in the next merge window, the change from non-blocking to blocking could cause side effects to the users of omapdss. So by making the functions block already will keep them behaving in the same manner. And, while not the main purpose of this patch, this will also remove the compile warning: drivers/video/omap2/dss/apply.c:350: warning: 'wait_pending_extra_info_updates' defined but not used Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
