Subject: [PATCH 01/03] sh: move sh asm/clock.h contents to linux/sh_clk.h V2
Date: Tue, 11 May 2010 13:29:17 +0000 [thread overview]
Message-ID: <20100511132917.9131.4098.sendpatchset@t400s> (raw)
From: Magnus Damm <damm@opensource.se>
This patch is V2 of the clock framework move from
arch/sh/include/asm/clock.h to include/linux/sh_clk.h
and updates the include paths for files that will be
shared between SH and SH-Mobile ARM.
The file asm/clock.h is still kept in this version,
this to depend on as few files as possible at this
point. We keep SH specific stuff in there.
