From 05ca556003b1d6b4df0b8831e4c07fad7f5bdd2c Mon Sep 17 00:00:00 2001 From: "Suthikulpanit, Suravee" Date: Wed, 10 Jun 2015 11:08:54 -0500 Subject: device property: Introduces device_dma_is_coherent() Currently, device drivers, which support both OF and ACPI, need to call two separate APIs, of_dma_is_coherent() and acpi_dma_is_coherent()) to determine device coherency attribute. This patch simplifies this process by introducing a new device property API, device_dma_is_coherent(), which calls the appropriate interface based on the booting architecture.
