2009-08-23	i2c: Runtime PM for SuperH Mobile I2C	Magnus Damm	1	-2/+37
	This patch modifies the SuperH Mobile I2C driver to support Runtime PM. These changes is all that is needed for proper Runtime PM support in this driver. Driver callbacks for Runtime PM are empty because the device registers are always re-initialized after pm_runtime_get_sync().

2009-07-30	i2c-sh_mobile: change module_init() to subsys_initcall()	Magnus Damm	1	-1/+1
	Convert the i2c-sh_mobile i2c bus driver to use subsys_initcall() instead of module_init(). This change makes the driver register a bit earlier which together with earlier platform data moves the time for probe(). The earlier probe() makes it possible to use i2c_get_adapter() and i2c_transfer() from device_initcall(). The same strategy is used by other i2c bus drivers such as i2c-pxa.c and i2c-s3c2410.c.

2009-07-15	i2c: Use resource_size	Julia Lawall	1	-1/+1
	Use the function resource_size, which reduces the chance of introducing off-by-one errors in calculating the resource size. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ struct resource *res; @@ - (res->end - res->start) + 1 + resource_size(res) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-01-07	i2c: Get rid of remaining bus_id access	Jean Delvare	1	-1/+1
	Use dev_name(dev) instead of accessing dev.bus_id directly, as the latter is going away soon. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Greg Kroah-Hartman <gregkh@suse.de> Cc: Kay Sievers <kay.sievers@vrfy.org>
2008-12-22	sh: sh_mobile i2c clock framework support	Magnus Damm	1	-37/+36
	Add clock framework support to the sh_mobile i2c driver and adjust the processor specific code accordingly. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-11-13	i2c: fix i2c-sh_mobile rx underrun	Magnus Damm	1	-1/+2
	Fix receive path underrun in i2c-sh_mobile driver. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-05	i2c: fix i2c-sh_mobile timing issues	Magnus Damm	1	-63/+208
	This patch teaches the i2c-sh_mobile driver to make use of wait irqs. Without this patch only dte irqs are used which may lead to overruns and cases of missing stop and extra bytes being read on the i2c bus. Use of wait irqs forces the hardware to pause and wait until the cpu is ready. Polling is also reworked in this patch to fix ms delay issues. Verified with bus analyzer and tested on MigoR and AP325RXA boards. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-04-22	i2c: New driver for the SuperH Mobile I2C bus controller	Magnus Damm	1	-0/+500
	This is V5 of the SuperH Mobile I2C Controller Driver. A simple Master only driver for the I2C block included in processors such as sh7343, sh7722 and sh7723. Tested on a sh7722 MigoR using a rs5c732b rtc. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org> Signed-off-by: Jean Delvare <khali@linux-fr.org>
