2008-04-22i2c: Fix platform driver hotplug/coldplugKay Sievers
Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable I2C platform drivers, to allow module auto loading.

2008-04-22i2c-bfin-twi: Add missing pin mux operationBryan Wu
Blackfin TWI controller hardware pin should be requested from GPIO port controller Before BF54x, there is no need to do this. But as long as BF54x and BF52x are supported by this generic driver, the missing pin mux operation should be added.

2008-04-22i2c-bfin-twi: Add platform_resource interface to support multi-port TWI ↵Bryan Wu

2008-01-27i2c-bfin-twi: Register adapter with a specific bus numberKalle Pokki
All the users of this driver explicitly specify the I2C bus numbers to be used in their platform data. Make the driver respect that. Signed-off-by: Kalle Pokki <kalle.pokki@eke.fi> Cc: Bryan Wu <bryan.wu@analog.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2007-10-13i2c-bfin-twi: Remove useless twi_lock mutexFrancis Moreau
Remove this unneeded mutex. Indeed it was used to serialize access to the hardware, but this is already done by the i2c-core layer, see 'bus_lock' mutex used by i2c_transfer().
