Subject: [PATCH v3 10/11] MIPS: mobileye: eyeq5: add 5 I2C controller nodes
Date: Wed, 06 Mar 2024 18:59:30 +0100	[thread overview]
Message-ID: <20240306-mbly-i2c-v3-10-605f866aa4ec@bootlin.com> (raw)
In-Reply-To: <20240306-mbly-i2c-v3-0-605f866aa4ec@bootlin.com>

Add the SoC I2C controller nodes to the platform devicetree. Use a
default bus frequency of 400kHz. They are AMBA devices that are matched
on PeriphID.

Set transfer timeout to 10ms instead of Linux's default of 200ms.

Acked-by: Linus Walleij <linus.walleij@linaro.org>
