iio: accel: add Freescale MMA7455L/MMA7456L 3-axis accelerometer driver
Add support for Freescale MMA7455L/MMA7456L 3-axis in 10-bit mode for I2C and SPI bus. This rather simple driver that currently doesn't support all the hardware features of MMA7455L/MMA7456L. Tested on Embedded Artist's LPC4357 Dev Kit with MMA7455L on I2C bus. Data sheets for the two devices can be found here: http://cache.freescale.com/files/sensors/doc/data_sheet/MMA7455L.pdf http://cache.freescale.com/files/sensors/doc/data_sheet/MMA7456L.pdf Signed-off-by: Joachim Eastwood <manabian@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
