From 7a3605bef87801bc7c86e23c608bd2d096433966 Mon Sep 17 00:00:00 2001 From: Gwendal Grignou Date: Wed, 28 Jul 2021 11:17:57 -0700 Subject: iio: sx9310: Support ACPI property Use device_property_read_... to support both device tree and ACPI bindings. Simplify the logic for reading "combined-sensors" array, as we assume it has been vetted at firmware build time.
