Subject: [PATCH 2/3] mfd: add tps65219 support
Date: Wed, 08 Jan 2025 16:24:09 +0100 [thread overview]
Message-ID: <20250108-k3-i2c-v1-2-cf088462217b@pengutronix.de> (raw)
In-Reply-To: <20250108-k3-i2c-v1-0-cf088462217b@pengutronix.de>
The tps65219 is a PMIC IC from Texas instruments. This patch adds basic
mfd support for this chip based on the corresponding Linux driver.
