[PATCH V10 2/2] i2c/designware: Provide i2c bus recovery support

2013-01-25 Thread Viresh Kumar 
Add bus recovery support for designware_i2c controller. It uses generic gpio
based i2c_gpio_recover_bus() routine. Platforms need to pass struct
i2c_bus_recovery_info as platform data to designware I2C controller.
