Masahiro Yamada	9242e72aae	i2c: use dev_get_drvdata() to get private data in suspend/resume hooks Several drivers call to_platform_device() to get platform_device and pass it to platform_get_drvdata(). In platform_get_drvdata(), the platform_device is converted back to struct device again. Use dev_get_drvdata() to avoid platform_device/device dance.

Joachim Eastwood	3f9c37a0c9	i2c: lpc2k: add driver Add support for the I2C controller found on several NXP devices including LPC2xxx, LPC178x/7x and LPC18xx/43xx. The controller is implemented as a state machine and the driver act upon the state changes when the bus is accessed. The I2C controller supports master/slave operation, bus arbitration, programmable clock rate, and speeds up to 1 Mbit/s.
