From 57e9befa4863fa4a3bb30f3cf511f79888e2de90 Mon Sep 17 00:00:00 2001 From: Chanho Park Date: Mon, 18 Oct 2021 21:42:13 +0900 Subject: dt-bindings: ufs: exynos-ufs: add io-coherency property Add "samsung,sysreg" regmap and the offset to the ufs shareability register for setting io coherency of the samsung ufs. "dma-coherent" property is also required because the driver code needs to know.
