Subject: [PATCH 3/4] arm64: dts: ls1012a: add gpio for i2c bus recovery
Date: Fri, 19 Jan 2024 15:10:34 -0500 [thread overview]
Message-ID: <20240119201035.3124007-3-Frank.Li@nxp.com> (raw)
In-Reply-To: <20240119201035.3124007-1-Frank.Li@nxp.com>
From: Li Yang <leoyang.li@nxp.com>
Add compatible string fsl,ls1012a-i2c and scl-gpios to support i2c bus
recovery when I2C bus lock by i2c devices.
[Leo: updated scl-gpios to match RM ]
