| Subject | [PATCH 2/2] arm64: tegra: Jetson-TX1: Add DT entry for system PMIC MAX77620 |
| Message-ID | <r7w3F-3yu-21@gated-at.bofh.it> |
| In reply to | #1345802 |
NVIDIA's Tegra210 platform Jetson-TX1 uses the Maxim Semiconductor's
PMIC MAX77620 as system PMIC.
Add DT entry for this device which enabled core registration,
GPIO, pin control, power sequencing and regulator functionalities.
This patch is created based on downstream data and new DT properties.

The patches for drivers of MFD/GPIO/Pincontrol are in flight.

Thanks, Thierry
