Subject: [PATCH v2 10/15] soc: renesas: Introduce ARCH_RCAR_GEN4
Date: Thu, 25 Jan 2024 16:34:38 +0100	[thread overview]
Message-ID: <a283913ba7a39ec2dae0ebf9fc2b06096f009511.1706194617.git.geert+renesas@glider.be> (raw)
In-Reply-To: <cover.1706194617.git.geert+renesas@glider.be>

Currently, all Kconfig symbols for R-Car Gen4 SoCs select the
ARCH_RCAR_GEN3 SoC family symbol, which might confuse the casual reader.

Fix this by introducing a new SoC family symbol for R-Car Gen4 SoCs.
For now this just selects ARCH_RCAR_GEN3, to avoid duplication, and to
relax dependencies.

Once "[PATCH] i2c: rcar: Prepare for the advent of ARCH_RCAR_GEN4"[1]
has been applied, ARCH_RCAR_GEN4 can stop selecting ARCH_RCAR_GEN3.
