| | * | | | | | | | OMAPDSS: Remove dss_debug variableChandrabhanu Mahapatra2012-10-12

Thus, the dependency on dss_debug variable is replaced with dyndbg in dynamic debugging mode and DEBUG flag otherwise. So, the dss_debug variable is removed along with checks for DEBUG flag.

| | * | | | | | | | OMAPDSS: Cleanup DSSDBG with dynamic pr_debug functionChandrabhanu Mahapatra2012-10-12

The use of dynamic debugging provides more flexibility as each debug statement can be enabled or disabled dynamically on basis of source filename, line number, module name etc., by writing to a control file in debugfs filesystem. For better understanding please refer to Documentation/dynamic-debug-howto.txt. The DSSDBGF() differs from DSSDBG() by providing function name. However, function name, line number, module name and thread ID can be printed through dynamic debug by setting appropriate flags 'f','l','m' and 't' in the debugfs control file. So, DSSDBGF instances are replaced with DSSDBG.

So, FIMD_V8_VIDTCON0 should be used. Signed-off-by: Jingoo Han <jg1.han@samsung.com>
