Subject: [PATCH v3 01/12] dt-bindings: serial: renesas,em-uart: Add RZ/V2M clock to access the registers
Date: Tue,  3 May 2022 12:55:46 +0100	[thread overview]
Message-ID: <20220503115557.53370-2-phil.edworthy@renesas.com> (raw)
In-Reply-To: <20220503115557.53370-1-phil.edworthy@renesas.com>

The RZ/V2M SoC has an additional clock to access the registers. The HW
manual says this clock should not be touched as it is used by the
"ISP Firmware".
