OMAP34xx, AM3517 and OMAP36xx platforms use dpll1 clock. OMAP443x, OMAP446x, OMAP447x, OMAP5, DRA7, AM43xx platforms use dpll_mpu clock. Latency used is the generic latency defined in omap-cpufreq driver. Signed-off-by: Nishanth Menon <nm@ti.com>
Hi Nishanth, After this patch, do you see any limitation to finally enabling 1Ghz operation on the beagle-xm by default? Or are we still missing a dependicy somewhere? cpufreq stats: 300 MHz:98.64%, 600 MHz:0.04%, 800 MHz:0.09%, 1000 MHz:1.23% (11) full cpufreq output: http://paste.debian.net/79073/
