2009-09-19[PATCH] i2c-imx: make bus available earlyWolfram Sang

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().

2009-08-20i2c-stu300: I2C STU300 stability updatesLinus Walleij
- blk clk is enabled when an irq arrives. The clk should be enabled, but just to make sure. - All error bits are handled no matter state machine state - All irq's will run complete() except for irq's that wasn't an event. - No more looking into status registers just in case an interrupt has happend and the irq handle wasn't executed. - irq_disable/enable are now separete functions. - clk settings calculation changed to round upwards instead of downwards. - Number of address send attempts before giving up is increased to 12 from 10 since it most times take 8 tries before getting through.

2009-07-30i2c-sh_mobile: change module_init() to subsys_initcall()Magnus Damm
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.

Add a sysfs interface to instantiate and delete I2C devices. This is primarily a replacement of the force_* module parameters implemented by some i2c drivers.

This can also be used when developing a driver on a self-soldered board which doesn't yet have proper I2C device declaration at the platform level, and presumably for various debugging situations.

2009-06-15i2c: Do not probe for TV chips on Voodoo3 adaptersJean Delvare
There's no point in giving the I2C bus of Voodoo3 adapters a class value, there's no video chip driver checking for it anymore. If support is ever needed, the video device should be instantiated explicitly rather than probed. To the best of my knowledge the only video chip that can be found on these boards is a BT869 video encoder, for which no support exists currently.
