Subject: [PATCH v1 0/4] arm64: dts: Mark Variscite i.MX9 I2C recovery GPIOs as open drain
Date: Sun, 18 Oct 2026 14:32:23 +0200 [thread overview]
Message-ID: <cover.1792326585.git.stefano.r@variscite.com> (raw)
The I2C recovery GPIOs on VAR-SOM-MX91 and VAR-SOM-MX93, including their
Symphony carrier boards, are missing the open-drain flag.
This series adds GPIO_OPEN_DRAIN to the SCL and SDA GPIO specifiers to
match the I2C bus requirements and avoid the warning emitted when the
I2C core enforces open-drain operation on SCL.
