Subject: [PATCH 1/2] ARM: shmobile: r8a7740: Remove legacy machine_desc.map_io() callback
Date: Thu, 28 Jan 2016 16:17:25 +0100	[thread overview]
Message-ID: <1453994246-12886-2-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1453994246-12886-1-git-send-email-geert+renesas@glider.be>

Commit 37201ba5c99d0be8 ("ARM: shmobile: r8a7740: Migrate to generic l2c
OF initialization") removed the last user of the legacy "IOMEM()" macro
on r8a7740-based systems. Hence there's no longer a need to set up a
transparent mapping of system I/O registers. Remove the mapping and the
legacy machine_desc.map_io() callback.
