ARM: tegra30: make the wait time of CPU power up to proportional to HZ
It would rather to use the API of time_to_jiffies than a constant number of jiffies for the wait time of CPU power up. Based on the work by: Sang-Hun Lee <sanlee@nvidia.com> Signed-off-by: Joseph Lo <josephl@nvidia.com> Signed-off-by: Stephen Warren <swarren@nvidia.com>
