Subject: [PATCH] Add I2C recovery handling for bcm-iproc based devices.

This patch adds I2C bus recovery support to the bcm-iproc I2C driver.
use the existing generic recovery mechanism by providing the hooks needed
to get and set the SCL and SDA lines.

The device must be placed in bit-bang mode before recovery starts and
returned to normal operation when complete.

Richard Laing (1):
  Add i2c recovery handling for bcm-iproc based devices.
