The check that variable val is less than zero is redundant since val is an unsigned int and hence can never be less than zero. Remove it. Signed-off-by:

Currently mount matrix is allowed in Device Tree, though there is no technical issue to extend it to support ACPI. Convert the function to use device_property_read_string_array() and thus allow to read mount matrix from ACPI if available. Example of use in _DSD method: Name (_DSD, Package () { ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"), Package () { Package () { "mount-matrix", Package() { "1", "0", "0", "0", "0.866", "0.5", "0", "-0.5", "0.866", } }, } }) At the same time drop the "of" prefix from its name and convert current users. No functional change intended. Signed-off-by: -

Document support for ADIS16480 Inertial Measurement Unit. Signed-off-by:
Stefan Popa <stefan.popa@analog.com> Reviewed-by:

Stefan Popa authored
The ADIS16495 and ADIS16497 are inertial systems that include a triaxis gyroscope and a triaxis accelerometer. The serial peripheral interface (SPI) provide a simple interface for data collection and configuration control. The devices are similar to ADIS16475, ADIS16480, ADIS16485 and ADIS16488, the main differences are highlighted below: * The temperature data scale is 0.00565 C/LSB for ADIS16475 and ADIS1648x devices, while for ADIS1649x 0.0125 C/LSB. * ADIS1649x devices support different gyroscope measurement ranges which are dependent on the dash number (-1, -2, -3), see Table 24 in the ADIS16495 datasheet. However, the ADIS16497 gyroscopes have the same scale as ADIS16495. * ADIS16495 devices support the acceleration maximum range of 8g, while ADIS16497 devices go up to 40g. * The internal clock for ADIS1649x devices is 4.25 kSPS. The sampling frequency is calculated by applying a decimation rate which can take a maximum value of 4250. * ADIS1649x devices support different default filter frequencies.

When setting the filter frequency, the driver looks into the adis16480_def_filter_freqs table for the best match. Pass this table to the chip_info struct since future devices will need to use a different table. Signed-off-by:

The adis1648x devices have an internal clock of 2.46 kSPS. The sampling frequency is calculated by applying a decimation rate which can take the maximum value of 2047. Although all adis1648x devices are similar in this regard, devices that will use this feature will be added in the future. Signed-off-by:

All supported devices provide internal temperature measurement from -40 C to +85 C, with +25 C representing value 0x00. This patch treats the temperature scale in a generic way, similar to the accelerometer and gyroscope scales. So far, there are no temperature max scale differences between the supported devices. However, devices that will make use of this feature will be added in the future. Signed-off-by:

The FNCTIO_CTRL register provides configuration control for each I/O pin (DIO1, DIO2, DIO3 and DIO4). This patch adds the option to configure each DIOx pin as data ready indicator with positive or negative polarity by reading the 'interrupts' and 'interrupt-names' properties from the devicetree. The 'interrupt-names' property is optional, if it is not specified, then the DIO1 pin is used as default data ready signal. Although the factory default assigns DIO2 as data ready signal, in the versions previous this patch, DIO1 pin was used. We should leave this configuration as is, since some devices might be expecting the interrupt on the wrong physical pin. Signed-off-by:
