From 7dd4cfd7f8c2976a8d65022146386480474501ca Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Wed, 20 Aug 2014 22:03:12 +0900 Subject: [PATCH] ARM: shmobile: Remove shmobile_setup_delay() All ARM mach-shmobile SoCs and boards now rely on DTS for CPU Frequency information, so remove the unused function shmobile_setup_delay(). While at it, make the function shmobile_setup_delay_hz() static.
