Subject: [PATCH 5/5] arm64: dts: renesas: r9a07g043u11-smarc-cru-csi-ov5645: Reduce I2C frequency
Date: Tue, 23 Jan 2024 12:17:20 +0000 [thread overview]
Message-ID: <20240123121720.294753-6-biju.das.jz@bp.renesas.com> (raw)
In-Reply-To: <20240123121720.294753-1-biju.das.jz@bp.renesas.com>
Reduce i2c freq from 400->100 kHz on RZ/G2UL SMARC EVK as the captured
image is not proper with the sensor configuration over I2C.
