| * staging:iio:adis16080: Move out of stagingLars-Peter Clausen2013-01-26
| | | | | | | | | | | | | | | | | | | | The driver is rather simple and in a good shape. It follows the IIO ABI and the standard codechecker tools do not report any issues, so move it out of staging. While moving it also remove one outdated 'fixme' comment. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

| * iio:adis16400: Add support for the adis16448Lars-Peter Clausen2013-01-26
| | | | | | | | | | | | | | | | | | | | The adis16448 is more or less from the same family of devices as supported by this driver. It features three acceleration channels, three angular velocity channels, three magnetometer channels, one temperature channels and one barometric pressure channel.

This includes for now the flash count, the product id and the serial number and raw register access.

| * iio:adis16400: Add support for the 52.85 Hz base sampling rateLars-Peter Clausen2013-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The adis16400 and similar have two different base sampling rate available, from which the actual sampling rate is derived. 1638 Hz and 52.85 Hz, switching to the lower base sampling rate allows to support lower sampling rates. This patch adds support for switching to the lower base sampling rate if the requested sampling frequency is outside of the range which can be supported by the higher base sampling rate. The function which is used to read the current sampling rate already has support for the lower sampling rate, so no changes are required there.

| * iio:adis16400: Increase samplerate precessionLars-Peter Clausen2013-01-26
| | | | | | | | | | | | | | | | | | The devices supported by this drivers support sample rates with less than one sample per second. To support this increase the samplerate precession to allow setting (and reading) the samplerate with a milli-HZ precession.

I changed snprintf() to scnprintf() to silence the warning. But since the buffer doesn't include space for the NUL terminator, we need to make it bigger or the "\n" will be truncated off.

| | | | | | | | | | | | | | | | This patch adds support for the ADIS16375, ADIS16480, ADIS16485, ADIS16488 6 degree to 10 degree of freedom IMUs. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
* | iio: Factor out fixed point number parsing into its own functionLars-Peter Clausen2012-11-20
| | | | | | | | | | | | | | | | | | Factor out the code for parsing fixed point numbers into its own function and make this function globally available. This allows us to reuse the code to parse fixed point numbers in individual IIO drivers. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
* | iio: Add pressure channel typeLars-Peter Clausen2012-11-20
| | | | | | | | | | | | | | | | This patch adds support for a new IIO channel type for pressure measurements. This can for example be used for barometric pressure sensors. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
* | iio:imu:adis: Add paging supportLars-Peter Clausen2012-11-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some of the newer generation devices from the ADIS16XXX series have more registers than what can be supported with the current register addressing scheme. These devices implement register paging to support a larger register range. Each page is 128 registers large and the currently active page can be selected via register 0x00 in each page. This patch implements transparent paging inside the common adis library. The register read/write interface stays the same and when a register is accessed the library automatically switches to the correct page if it is not already selected. The page number is encoded in the upper bits of the register number, e.g. register 0x5 of page 1 is 0x85.

* | iio:gyro: Add support for the ADIS16136 gyroscopeLars-Peter Clausen2012-11-20
| | | | | | | | | | | | | | | | This patch adds support for the ADIS16133, ADIS16135, ADIS16136 single channel gyroscopes. The main difference between them is the sensor precision. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
* | iio:imu:adis: Add support for 32bit registersLars-Peter Clausen2012-11-20
| | | | | | | | | | | | | | | | | | Some of the newer generation devices from the ADIS16XXX family have 32bit wide register which spans two 16bit wide registers. This patch adds support for reading and writing a 32bit wide register. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
* | iio:imu:adis: Add debugfs register access supportLars-Peter Clausen2012-11-20
| | | | | | | | | | | | | | | | | | Provide a IIO debugfs register access function for the ADIS library. This function can be used by individual drivers to allow raw register access via debugfs. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
* | staging:iio: Move the ad7298 driver out of stagingLars-Peter Clausen2012-11-19
| | | | | | | | | | | | | | | | The driver does not expose any custom API to userspace and none of the standard static code checker tools report any issues, so move it out of staging. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
