For RZ/G1, the SoC-specific compatible match entry can be removed from the driver: their DT always had the family-specific compatible values, and thus there was never a need to add the SoC-specific compatible values to the driver. For R-Car Gen2 and M3-W, the SoC-specific compatible match entries can be removed, too, as there are a few points in time where DT backwards-compatibility was broken for other reasons: - Legacy DT clock support is no longer supported since commit 58256143cff7c2e0 ("clk: renesas: Remove R-Car Gen2 legacy DT clock support") in v5.5, and the addition of "renesas,rcar-gen2-msiof" to DTS in v4.11 predates the completion of the clock conversion in v4.15, - Legacy DT LVDS support is no longer supported since commit 841281fe52a769fe ("drm: rcar-du: Drop LVDS device tree backward compatibility") in v5.18, and the addition of "renesas,rcar-gen3-msiof" in commit 8b51f97138ca22b6 ("arm64: dts: r8a7796: Use R-Car Gen 3 fallback binding for msiof nodes") in v4.11 predates the LVDS conversion in commit 58e8ed2ee9abe718 ("arm64: dts: renesas: Convert to new LVDS DT bindings") in v4.20. For R-Car H3, the SoC-specific compatible match entry cannot be removed, as its purpose is to handle an SoC-specific quirk.
