From dd5ddd3c7a8c7ac382a82d15757f0ca3ab2b2dbc Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Thu, 24 Oct 2019 16:57:39 +0100 Subject: iommu/io-pgtable-arm: Rename IOMMU_QCOM_SYS_CACHE and improve doc The 'IOMMU_QCOM_SYS_CACHE' IOMMU protection flag is exposed to all users of the IOMMU API. Despite its name, the idea behind it isn't especially tied to Qualcomm implementations and could conceivably be used by other systems. Rename it to 'IOMMU_SYS_CACHE_ONLY' and update the comment to describe a bit better the idea behind it. Cc: Robin Murphy Cc: "Isaac J.
