X-Git-Tag: upstream/snapshot3+hdmi~5689^2~4^2~4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3e27996ca876a4cf38b4821140819e962104f82c;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

cpufreq: dbx500: Move clk_get to probe

The armss clock shall only be fetched at probe thus move this here.
Same thing goes for the printing of the available frequencies.
