Subject: [PATCH v2 2/5] ARM: dts: rzg1: Add generic compatible strings to IIC nodes
Date: Fri, 18 Jun 2021 13:04:08 +0200	[thread overview]
Message-ID: <573c8ca99f3924a96000fb328a84f1f6d421c6af.1624013699.git.geert+renesas@glider.be> (raw)
In-Reply-To: <cover.1624013699.git.geert+renesas@glider.be>

According to the Hardware User's Manual, automatic transmission for PMIC
control (DVFS) is not available" on RZ/G1 SoCs.  This really means that
support for automatic DVFS is not present, while the IIC automatic
transmission feature itself is still available, albeit not super useful.

Hence there is no longer a reason not to declare compatibility with the
R-Car Gen2-specific and generic versions.
