drm/omap: move omapdss & displays under omapdrm

2015-12-29T09:07:48+00:00

Now that omapfb has its own copy of omapdss and display drivers, we can
move omapdss and display drivers which omapdrm uses to omapdrm's
directory.

We also need to change the main drm Makefile so that omapdrm directory
is always entered, because omapdss has a file that can't be built as a
module.

OMAPDSS: DSS: fix a warning message

2015-12-29T09:06:31+00:00

The WARN() macro has to take a condition.  The current code will just
print the stack trace and the function name instead of the intended
warning message.

video: omapdss: delete unneeded of_node_put

2015-12-29T09:06:30+00:00

Device node iterators perform an of_node_put on each iteration, so putting
an of_node_put before a continue results in a double put.

A simplified version of the semantic match that finds this problem is as
follows (http://coccinelle.lip6.fr):

// 
@@
expression root,e;
local idexpression child;
iterator i;
@@

 i(..., child, ...) {
   ... when != of_node_get(child)
*  of_node_put(child);
   ...
*  continue;
}
//

OMAPDSS: DSI: cleanup DSI_IRQ_ERROR_MASK define

DSI_IRQ_SYNC_LOST was ORed twice so we can remove one.

OMAPDSS: remove extra out == NULL checks

2015-12-29T09:06:29+00:00

All the output drivers check for 'out' being NULL, but it can never be
NULL. Remove the check.

OMAPDSS: change internal dispc functions to static

2015-12-29T09:06:29+00:00

A bunch of dispc functions are only used inside dispc, so we can make
them static.

OMAPDSS: make a two dss feat funcs internal to omapdss

2015-12-29T09:06:29+00:00

dss_feat_get_supported_displays() and dss_feat_get_supported_outputs()
are not used outside omapdss, but are exported. We can thus remove the
export and move the declarations to the omapdss internal header.

OMAPDSS: remove extra EXPORT_SYMBOLs

2015-12-29T09:06:28+00:00

The functions dispc_ovl_set_fifo_threshold and
dispc_ovl_compute_fifo_thresholds are exported, but not declared in
public headers, and thus are not used outside omapdss. So we can remove
the EXPORT_SYMBOL()s.

OMAPDSS: add setup for WB capture mode in dispc_wb_setup()

2015-12-29T09:06:28+00:00

dispc_wb_setup() handles configuration only for mem-to-mem case. This
patch adds the necessary configuration to handle also display capture
mode.

We need to set CAPTUREMODE to 0 (continuous capture), and WBDELAYCOUNT
according to the vertical timings of the display, so that the WB FIFO
has time to flush before the next frame starts.
