[PATCH 2/2] arm64: tegra: Jetson-TX1: Add DT entry for system PMIC MAX77620

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
