From 001d50c9a14f1fab94b329161a1db9235b4e60da Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 30 Nov 2017 12:54:28 +0100 Subject: PM / Domains: Remove obsolete "samsung,power-domain" check Currently the generic PM Domain code code checks for the presence of both (generic) "power-domains" and (Samsung Exynos legacy) "samsung,power-domain" properties in all device tree nodes representing devices. There are two issues with this: 1. This imposes a small boot-time penalty on all platforms using DT, 2. Platform-specific checks do not really belong in core framework code. Remove the platform-specific check, as the last user of "samsung,power-domain" was removed in commit 46dcf0ff0de35da8 ("ARM: dts: exynos: Remove exynos4415.dtsi"). All other users were converted before in commit 0da6587041363033 ("ARM: dts: convert to generic power domain bindings for exynos DT").
