Subject: [PATCH v5 2/2] arm64: dts: mediatek: enable i2c0 for mt8365-evk board
Date: Mon, 27 Mar 2023 10:27:58 +0200	[thread overview]
Message-ID: <20221122-mt8365-i2c-support-v5-2-6e4f3b54937f@baylibre.com> (raw)
In-Reply-To: <20221122-mt8365-i2c-support-v5-0-6e4f3b54937f@baylibre.com>

Enable the I2C0 bus provides communication with:
- The integrated RT9466 Switching Battery Charger.
- The integrated MT6691 LP4X buck for VDDQ.
- The integrated MT6691 LP4X buck for VDD2.
- The pin header, to plug external I2C devices.
