From bb178da701382a230e26d90cf94e8a24b280e0d9 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Thu, 22 May 2014 20:02:14 +0200 Subject: [PATCH] clk: shmobile: mstp: Fix the is_enabled() operation The MSTP[SC]R registers have clock stop bits, not clock enable bits. The bit value should thus be inverted in the is_enabled() operation.
