* iio: gyro: bmi055 gyro sensor driverIrina Tirdea2014-09-142-13/+28
| | | | | | | | | | | | | | | | | | Add support for the BMI055 gyroscope sensor. BMI055 is a package consisting of an acceleration sensor and a gyroscope. This patch adds support for the gyroscope only. Spec downloaded from: http://ae-bst.resource.bosch.com/media/products/dokumente/bmi055/BST-BMI055-DS000-06.pdf The BMI055 gyroscope uses the same register definition as BMG160, but does not specify a temp register. However, the temp register seems to be working in the same way as for BMG160, so this patch does not remove the temp channel for BMI055.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The following chips are either similar or have only the resolution different. Hence, change this driver to support these chips too: BMI055 - combo chip (accelerometer part is identical to BMC150's) BMA255 - identical to BMC150's accelerometer BMA222E - 8 bit resolution BMA250E - 10 bit resolution BMA280 - 14 bit resolution Additionally: * add bmc150_accel_match_acpi_device() function to check that the device has been enumerated through ACPI; * rename bmc150_accel_acpi_gpio_probe() to bmc150_accel_gpio_probe() since the ACPI matching has been moved to the new function. Also, this will allow for the GPIO matching to be done against a device tree too, not only ACPI tree; * rename bmc150_scale_info struct member 'range' to 'reg_range' to be consistent with the naming convention used elsewhere in the driver and declare it u8, instead of int; * change CONFIG description to list all supported chips; Signed-off-by: Laurentiu Palcu <laurentiu.palcu@intel.com> Acked-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

* staging: iio: light: isl29018: add support for isl29023 and isl29035Laurentiu Palcu2014-08-301-22/+141
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intersil chips ISL29018, ISL29023 and ISL29035 are very similar. They're all ambience light sensors. The ISL29018, however, is also a proximity sensor. The registers are similar too: -------------+----------+---------- AVAILABLE IN | ADDR REG | NAME 290xx | | -------------+----------+---------- 18/23/35| 00h| COMMANDI 18/23/35| 01h| COMMANDII (B4-7 are used only in 29018 for proximity) 18/23/35| 02h| DATALSB 18/23/35| 03h| DATAMSB 18/23/35| 04h| INT_LT_LSB 18/23/35| 05h| INT_LT_MSB 18/23/35| 06h| INT_HT_LSB 18/23/35| 07h| INT_HT_MSB 18/23| 08h| TEST 35| 0Fh| ID -------------+----------+----------- So, this patch will add support for ISL29023 and ISL29035 to the existing isl29018 driver. Since these 2 chips don't have proximity detection, the proximity sysfs attribute is not needed. Also, for ISL29035, since it has an ID register, make use of it in order to properly detect the chip and clear the brownout bit.

Maintainer Updates * Add 3 designated reviewers for IIO. Lars, Peter and Hartmut have been actively reviewing a lot of patches for a while now so this reflects the status quo. These three are probably the only reason I keep my head above the water! New drivers and device support * max5821 DAC * Rockchip SARADC * TI ADC128S052 ADC * BMC150 Accelerometer * exynos ADC driver gains support for s3c24xx and s3c64xx parts. * kxcjk-1013 gainst range control and runtime PM support to drive down it's power usage. Driver removals * Drop ad5930, ad99850, ad9852, ad9910 and ad9951 drivers on the simple basis that they drivers just provided a register write function with no compliant user space ABI whatsoever. Much better to drop them and start again for these in the fullness of time. Core Enhancements * Join together neighbouring elements in the demux units that feeds the binary interfaces. This cuts down on the number of individual copies needed when splitting out individual channels from the incoming channel scans. * Other demux related cleanups such as using roundup instead of a local implementation. Cleanups * Drop an unnecessary double setting of the owner field in xilinx adc. * Some more patches to use managed (devm) interfaces to cut down on complexity of removal code. * adis16060 coding style fixlets. * Fix some incorrect error returns in the Xilinx ADC driver. * Coding style fixlets for various accelerometer drivers. * Some sparse warning fixes to do with endianness and sign of variables. * Fix an incorrect and entirely pointless use of sizeof on a dynamic pointer in hid-sensor-magn-3d by dropping the relevant code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All what these 'drivers' do is expose a single (non standard ABI) sysfs attribute that when written to does a direct pass-through to spi_write(). This is rather ugly and does not justify the existence of a driver as the same can easily done by using the spidev interface. The drivers will eventually be rewritten as proper IIO ABI compliant drivers which do have the proper abstraction layers between userspace and the device. But in the meantime these driver do not add any extra value and just clutter up the staging area. So just remove them.

This driver only implements accelerometer part. Spec downloaded from: http://ae-bst.resource.bosch.com/media/products/dokumente/bmc150/BST-BMC150-DS000-03.pdf This sensor chip supports many advanced features, but this driver implements minimum feature set which is a must to be useful. This driver can be enhanced incrementally. If the sensor vendor wants to update full featured version, they can substitute or enhance this driver when they get chance.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In an effort to improve raw read performance and at the same time enter low power state at every possible chance. For raw reads, it will keep the system powered on for a default or user specified time, via autosuspend_delay attribute of device power. This will help read multiple samples without power on/off sequence. For triggers it will keep the system on till, requested to be turned off by trigger state by utilizing run time PM usage counters. When runtime pm is not enabled, then it keeps the chip in operation mode always.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert a zero return value on error to a negative one, as returned elsewhere in the function. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
