Subject: [PATCH 05/05] sh: add IORESOURCE_CLK to SuperH Mobile I2C platform data
Date: Fri, 18 Jul 2008 16:40:44 +0900 [thread overview]
Message-ID: <20080718074044.32713.83039.sendpatchset@rx1.opensource.se> (raw)
In-Reply-To: <20080718074002.32713.73442.sendpatchset@rx1.opensource.se>
From: Magnus Damm <damm@igel.co.jp>
This patch passes processor specific IORESOURCE_CLK information to the
i2c-sh_mobile driver. With this change the clock to the IIC block will
be disabled while the I2C bus is inactive. Without this patch the clock
is always on.
