From 8aaddb03b6d1f469a2c3d22c84a759375e10974d Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 24 Feb 2016 09:43:23 +0100 Subject: [PATCH] drivers: sh: Restore legacy clock domain on SuperH platforms CONFIG_ARCH_SHMOBILE is not only enabled for Renesas ARM platforms (which are DT based and multi-platform), but also on a select set of Renesas SuperH platforms (SH7722/SH7723/SH7724/SH7343/SH7366). Hence since commit 60f90f37a988b6ed ("drivers: sh: Get rid of CONFIG_ARCH_SHMOBILE_MULTI"), the legacy clock domain is no longer installed on these SuperH platforms, and module clocks may not be enabled when needed, leading to driver failures. To fix this, add an additional check for CONFIG_OF. Fixes: 60f90f37a988b6ed ("drivers: sh: Get rid of CONFIG_ARCH_SHMOBILE_MULTI").
