Subject: [PATCH] ARM: dts: marzen: Enable I2C support
Date: Mon, 20 Mar 2023 17:34:24 +0100 [thread overview]
Message-ID: <77b87378397fd26f39c73f68e3ea465db6d38fb1.1679330016.git.geert+renesas@glider.be> (raw)
Enable the single I2C bus available on the Marzen development board.
As this bus contains an AK4643 codec, it must be limited to 100 kHz.
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>

To be queued in renesas-devel-for-v6.4.
