[PATCH V2 2/2] ARM64: tegra: Add device node for system PMIC MAX77620
Laxman Dewangan

Tue Jun 7 04:44:57 PDT 2016
Jetson-TX1 uses the Maxim MAX77620 as system Power management IC.
Add device node for the MAX77620 with following details:
- Add device max77620 with.
- Add all pins configurations.
- Configure FPS of the device.
- Configure SD/DCDC and LDOs regulators.
- populate the bus expander on base board P2597.
- Populate all fixed voltage regulators controlled by GPIOs from Tegra,
PMIC and bus expanders.
For the different details, jetson-CV device tree files are referred from
downstream.

Changes from V1:
- Rebase change and populated based on applied patches.
