Subject: [PATCH 2/6] MIPS: mobileye: eyeq5: add 5 I2C controller nodes
Date: Fri, 04 Jul 2025 13:47:07 +0200	[thread overview]
Message-ID: <20250704-of-commits-v1-2-dc2006bf2846@bootlin.com> (raw)
In-Reply-To: <20250704-of-commits-v1-0-dc2006bf2846@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>
