From 4c6d7e228968bdc238ae7213d919f34b7838fe59 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Fri, 20 May 2016 09:50:54 +0200 Subject: [PATCH 1/2] drivers: sh: Stop using the legacy clock domain on ARM Since commits 71d076ceb245f0d9 ("ARM: shmobile: Enable PM and PM_GENERIC_DOMAINS for SoCs with PM Domains") and 2ee98234b88174f2 ("arm64: renesas: Enable PM and PM_GENERIC_DOMAINS for SoCs with PM Domains"), CONFIG_PM and CONFIG_PM_GENERIC_DOMAINS are enabled unconditionally for Renesas ARM-based SoCs. Hence the legacy clock domain is no longer used on these SoCs. Remove the related support code, and stop entering drivers/sh/ on ARM.
