Subject: [PATCH v4 13/16] dt-bindings: ufs: exynos-ufs: add io-coherency property
Date: Thu, 7 Oct 2021 17:09:31 +0900 [thread overview]
Message-ID: <20211007080934.108804-14-chanho61.park@samsung.com> (raw)
In-Reply-To: <20211007080934.108804-1-chanho61.park@samsung.com>
Add "samsung,sysreg" regmap and the offset to the ufs shareaibility
register for setting io coherency of the samsung ufs. "dma-coherent"
property is also required because the driver code needs to know.
