Subject: [PATCH 08/10] ARM: shmobile: Remove shmobile_setup_delay()
Date: Wed, 20 Aug 2014 13:03:12 +0000 [thread overview]
Message-ID: <20140820130312.32075.52599.sendpatchset@w520> (raw)
From: Magnus Damm <damm+renesas@opensource.se>
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.
