Subject: [PATCH v2 3/3] arm64: dts: qcom: monaco-arduino-monza: add ina232 power sensor
Date: Thu, 11 Jun 2026 16:05:26 +0200 [thread overview]
Message-ID: <20260611-monza-ina232-v2-3-e4375ce652d0@oss.qualcomm.com> (raw)
In-Reply-To: <20260611-monza-ina232-v2-0-e4375ce652d0@oss.qualcomm.com>
The Arduino Monza board has a TI INA232 current/power monitor connected
on I2C12 at address 0x40. It is used to measure the board supply current
through a 2 milliohms shunt resistor.
