Subject: display: Support display setup when the dpms initialization done
X-Git-Tag: accepted/tizen/unified/20240912.084746~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4a8cec17ddaae4d3659e4a19ae5aa23ec36698f2;p=platform%2Fcore%2Fsystem%2Fplugin%2Fdeviced-headed.git

display: Support display setup when the dpms initialization done

When the dpms initialization is done, display state is set to DISPLAY_STATE_ON.
And then, normal state timeout counting starts.
After normal state timeout, display state can be changed to other state.
To support above description, this patch is necessary.
