Program vdd_core for Jetson TK1 to 1V, which is the max safe voltage for ultra low temperature operations. vdd_cpu and vdd_gpu are already at 1V. Signed-off-by: Bibek Basu <bbasu@nvidia.com> (swarren: fixed comments to better match the code) (swarren: moved board ifdef around data in header, made code generic) (swarren: fixed typos in commit description) Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
