Hi,

Currently I am working on an Nvidia Jetson Tk1 board.

With u-boot v2016.05 I am seeing the following messages on the start up

[ 0.000000] Tegra clk 127: register failed with -17 [ 0.004488] /cpus/cpu@0 missing clock-frequency property [ 0.008002] /cpus/cpu@1 missing clock-frequency property [ 0.013406] /cpus/cpu@2 missing clock-frequency property [ 0.018751] /cpus/cpu@3 missing clock-frequency property [ 0.879130] +USB0_VBUS_SW: Failed to request enable GPIO108: -517 [ 0.883400] reg-fixed-voltage regulators:regulator@7: Failed to register regulator: -517 [ 0.891700] +5V_USB_HS: Failed to request enable GPIO109: -517 [ 0.897438] reg-fixed-voltage regulators:regulator@8: Failed to register regulator: -517 [ 0.905852] +1.05V_RUN_AVDD_HDMI_PLL: Failed to request enable GPIO63: -517 [ 0.912605] reg-fixed-voltage regulators:regulator@11: Failed to register regulator: -517 [ 0.920982] +5V_HDMI_CON: Failed to request enable GPIO86: -517 [ 0.926818] reg-fixed-voltage regulators:regulator@12: Failed to register regulator: -517 [ 0.935194] +5V_SATA: Failed to request enable GPIO242: -517 [ 0.940771] reg-fixed-voltage regulators:regulator@13: Failed to register regulator: -517 [ 0.949148] +12V_SATA: Failed to request enable GPIO242: -517 [ 0.954811] reg-fixed-voltage regulators:regulator@14: Failed to register regulator: -517 [ 2.740489] tegra-xusb-padctl 7009f000.padctl: failed to setup XUSB ports: -517 [ 2.757663] tegra-pcie 1003000.pcie-controller: Failed to get supply 'avddio-pex': -517 [ 2.784372] serial-tegra serial@70006000: failed to get alias id, errno -19 [ 2.791460] serial-tegra serial@70006040: failed to get alias id, errno -19

I am not sure about what's the issue here. Google search shows something might be missing in the device tree. Can you let me know whats the issue here.
