From a84ef0d181d917125f1f16cffe53f84c19968969 Mon Sep 17 00:00:00 2001 From: Joachim Eastwood Date: Sat, 31 Oct 2015 13:49:16 +0100 Subject: 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 Signed-off-by: Jonathan Cameron --- drivers/iio/accel/mma7455.h | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) create mode 100644 drivers/iio/accel/mma7455.h (limited to 'drivers/iio/accel/mma7455.h') diff --git a/drivers/iio/accel/mma7455.h b/drivers/iio/accel/mma7455.h new file mode 100644 index 000000000000..2b1152c53d4f --- /dev/null +++ b/drivers/iio/accel/mma7455.h @@ -0,0 +1,19 @@ +/* + * IIO accel driver for Freescale MMA7455L 3-axis 10-bit accelerometer + * Copyright 2015 Joachim Eastwood + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. + */ + +#ifndef __MMA7455_H +#define __MMA7455_H + +extern const struct regmap_config mma7455_core_regmap; + +int mma7455_core_probe(struct device *dev, struct regmap *regmap, + const char *name); +int mma7455_core_remove(struct device *dev); + +#endif -- cgit v1.2.3
