| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The I2C devices that make up the STMicroelectronics MEMS sensors may be sneakily enabled by cleverly giving the device node the same name as a string match from the platform device ID table. However the right method is to use the compatible string. On detection, the ST sensors use the ID string to probe and instatiate the right sensor driver, so pass the kernel-internal ID string in the .data field of the OF match table, and set the I2C client name to this name when a compatible match is used. This avoids having misc Linux-specific strings floating around in the device tree.

A mixed bag of fixes, many of which feel just to late for 3.15. * hid sensors - some devices need a feature report request in order to change power state. This isn't part of the spec, but has been observed on several devices and does no harm to others. * mpl3115 has had two errors in the buffer description fixed. The presure is signed, not unsigned and the temperature has 12 bits rather than 16. These could lead to incorrect interpretation of the data in userspace. * tsl2x7x - the high byte of the proximity thresholds should be written along with the low byte (which was). This could lead to interesting results with large thresholds. * twl4030 - a flag to specify processed values were required was not set when initializing a reading. As such values returned were in an unknown state. Fixed by simply initializing it appropriately. * IIO_SIMPLE_DUMMY_BUFFER did not select IIO_BUFFER leading to randconfig build errors. * ak8975 was applying an unwanted le16_to_cpu conversion as the i2c framework already performs one. As such for big endian systems, the bytes would be in the wrong order in the magnetic field measurements reported. * mxs-lradc - the controllable voltage dividers were not enabled / disabled for later channels than the first one during conversion. * at91_adc error handling returned -ENOMEM in a u8. Return value of at91_adc_get_trigger_value_by_name changed to int thus allowing -ENOMEM and also original values to be returned. * mcb - mcb_request_mem returns and ERR_PTR but the caller was checking for NULL to detect an error.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added IIO magnetometer driver for AK09911. In functionality is resembles AK8975 or AK8963. But there are several differences, so instead of modifying existing AK8975 driver and keep it clean, implemented as a separate driver. The key differences are: - Register map is different and have different indexes - AK09911 is a very compact interface with no DRDY pin. So no support of interrupt or GPIO poll - Even for polled mode no mention on ST2 register, which is required in ak8975 driver - mode values are different for fuse access Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the pressure sensor has code to retrieve and enable two regulators for Vdd and Vdd IO, but actually these voltage inputs are found on all of these ST sensors, so move the regulator handling to the core and make sure all the ST sensors call these functions on probe() and remove() to enable/disable power. Here also mover over to obtaining the regulator from the *parent* device of the IIO device, as the IIO device is created on-the-fly in this very subsystem it very unlikely evert have any regulators attached to it whatsoever. It is much more likely that the parent is a platform device, possibly instantiated from a device tree, which in turn have Vdd and Vdd IO supplied assigned to it.

So I have fixed calculation formula And add RAW_TO_GAUSS macro. ASA is in the range of 0 to 255. If multiply 0.003, calculation result(in_magn_[*]_scale) is always 0. So multiply 3000 and return and IIO_VAL_INT_PLUS_MICRO. As a result, read_raw call back function return accurate scale value.

| | | | | | | | | | | The IIO_ST macro no longer covers all the elements of struct scan_type and has this has lead to some bugs being introduced. The drivers are easier to follow with this structure being directly filled so that is now preferred. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Acked-by: Lars-Peter Clausen <lars@metafoo.de>

| | | | | | | | | | | | | | | | | | | | | | We can't store the trigger instance created by iio_trigger_alloc, in trig field of iio_device structure. This needs to be stored in the driver private data. Othewise it can result in crash during module unload. Hence created a trig_ptr in the common data structure for each HID sensor IIO driver and storing here.
