Subject: 	Updating UI to show the battery percentage increase every 60s
X-Git-Tag: 2.1b_release~1145
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=079e80a691e9db19d4a3544a8469d6d198f19c7e;p=kernel%2Fkernel-mfld-blackbay.git

	Updating UI to show the battery percentage increase every 60s

	BZ: 24777

	Whenever charger is connected/removed to the platform the UI should
	update the battery percetange increasing/decreasing. So, the UI update
	is done using the polling method rightnow. The interrupt based solution
 	is WIP and needs to be verified on few platforms before going into
	mainline.
