Subject: [PATCH] arm64: dts: renesas: rzg2ul-smarc: Enable CRU, CSI support
Date: Tue, 13 Feb 2024 14:11:25 +0000	[thread overview]
Message-ID: <20240213141125.159758-1-biju.das.jz@bp.renesas.com> (raw)

Enable CRU, CSI on RZ/G2UL SMARC EVK and tie the CSI to the OV5645 sensor
using Device Tree overlay.

Note:
 * This patch has a functional dependecy [1]
   [1] https://lore.kernel.org/all/20240213140240.159057-1-biju.das.jz@bp.renesas.com/
v2->v3:
 * Added missing r9a07g043u11-smarc-cru-csi-ov5645.dtbo entry in Makefile.
 * Made this as separate patch as SoC dtsi is accepted and dropping the
   i2c workaround patch for ov5645.
v1->v2:
 * No change.
