Subject: [PATCH 14/16] clk: renesas: Add support for R9A07G044L SoC
Date:   Fri, 14 May 2021 20:22:16 +0100
Message-Id: <20210514192218.13022-15-prabhakar.mahadev-lad.rj@bp.renesas.com>
In-Reply-To: <20210514192218.13022-1-prabhakar.mahadev-lad.rj@bp.renesas.com>
References: <20210514192218.13022-1-prabhakar.mahadev-lad.rj@bp.renesas.com>
Precedence: bulk

Define the clock outputs supported by RZ/G2L (R9A07G044) SoC
and bind it with RZ/G2L CPG core.

Based on a patch in the BSP by Binh Nguyen
<binh.nguyen.jz@renesas.com>.
