Subject: [PATCH v6 1/3] spi: dt-bindings: snps,dw-apb-ssi: Merge duplicate compatible entry
Date: Fri, 25 Apr 2025 10:28:12 +0800	[thread overview]
Message-ID: <20250425-sfg-spi-v6-1-2dbe7bb46013@gmail.com> (raw)
In-Reply-To: <20250425-sfg-spi-v6-0-2dbe7bb46013@gmail.com>

Microsemi Ocelot/Jaguar2, Renesas RZ/N1 and T-HEAD TH1520
SoC-specific compatibles, which eventually fallback to the
generic DW ssi compatible, it's better to combine them in single entry
