OMAP: PM: CPUfreq: obey min/max settings of policy
Use the min/max settings from CPUfreq policy rather than processor defined min/max settings. Without this patch, it's possible to scale frequency outside the current policy range. Signed-off-by: Eero Nurkkala <ext-eero.nurkkala@nokia.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
