Subject: [PATCH v2 1/2] dt-bindings: mmc: spacemit,sdhci: add support for K3 SoC
Date: Thu, 22 Jan 2026 17:37:30 +0800	[thread overview]
Message-ID: <20260122-07-k3-mmc-v2-1-3c3ffef25e94@kernel.org> (raw)
In-Reply-To: <20260122-07-k3-mmc-v2-0-3c3ffef25e94@kernel.org>

The SDHCI controller found on SpacemiT K3 SoC share the same IP with
K1 generation, while fixed the broken 64BIT DMA issue. Introduce a
compatible string to enable support for it.
