Subject: [PATCH 4.19.y-cip 9/9] arm64: dts: renesas: rzg2: Add RPC-IF Support
Date: Thu, 14 Mar 2024 19:29:50 +0000	[thread overview]
Message-ID: <20240314192950.27343-10-prabhakar.mahadev-lad.rj@bp.renesas.com> (raw)
In-Reply-To: <20240314192950.27343-1-prabhakar.mahadev-lad.rj@bp.renesas.com>

From: Adam Ford <aford173@gmail.com>

commit 8811955d0a6d0abfa3e1c0cee30090fda0015069 upstream.

The RZ/G2 series contain the SPI Multi I/O Bus Controller (RPC-IF).
Add the nodes, but make them disabled by default.
