+Commit a5b6b67364cb ("arm64: tegra: Add ID EEPROM for Jetson TX1
+module") populated the EEPROM on the Jetson TX1 module, but did not
+enable the corresponding I2C controller. Enable the I2C controller so
+that this EEPROM can be accessed.

+The following warning is observed on Jetson TX1, Jetson Nano and Jetson
+TX2 platforms because the supply regulators are not specified for the
+EEPROMs.
+
+ WARNING KERN at24 0-0050: 0-0050 supply vcc not found, using dummy regulator
+ WARNING KERN at24 0-0057: 0-0057 supply vcc not found, using dummy regulator
+
+For both of these platforms the EEPROM is powered by the main 1.8V
+supply rail and so populate the supply for these devices to fix these
+warnings.

+The following warning is observed on the Jetson TX2 platform ...
+
+ WARNING KERN tegra-sor 15540000.sor: 15540000.sor supply \
+              vdd-hdmi-dp-pll not found, using dummy regulator
+
+The problem is caused because the regulator for the SOR device is
+missing the '-supply' suffix in Device-Tree. Therefore, add the
+'-supply' suffix to fix this warning.
