2017-07-01iio: adc: at91-sama5d2_adc: add support for suspend/resume functionalityEugen Hristev1-10/+80
Added support for suspend/resume functionality for the ADC IP in sama5d2 SoC. In order to enter Suspend to ram mode (backup + self refresh mode for memory), in which the ADC IP is no longer powered, we need to reset the pins to default state, for the scenario when they are also used for I2C bus to communicate with the PMIC. On resume, we need to reconfigure the ADC IP registers and reconfigure the trigger registers in the case when the suspend procedure is done while sysfs has the buffer and trigger enabled. In the case the suspend happens exactly during a software triggered conversion, the request will time out, because we reset and power down the ADC.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Second set of IIO new device support, features and cleanups for the 4.13 cycle. A few reverts here. One was a general failure to notice a device was already supported by another driver. The second is due to a review comment pointing out that the original patch was a bad idea and would break existing systems. Reverts * bma180 - Revert addition of support for the BMA250E it is already supported by the bmc150-accel and better supported at that. Oops. * hi8435 - The fix for cleanup of the reset gpio stuff isn't a good way to go. It breaks systems where an inverting level convertor is used. The right fix is to make the original devicetree correct - even if it involves patching the devicetree in kernel. New Device Support * stm32-adc - STM32H7 support and bindings. Features * core - add a hardware triggered operating mode for systems in which the actual trigger is never seen by the kernel. This is typically only used when a device 'can' use other triggers, but if a particular magic one is enabled the interrupt is effectively handled in hardware and we never see it. * st-lsm6dsx - support active low interrupts. * stm32-adc - Make the core adc clock optional as not all hardware supported requires it. - Make the bus clock optional in the per instance driver as it may be shared by all instances of the ADC and is handled by the core. - Rework to have a data structure representing the device type specific elements. * stm32-trigger (and counter) - Use the INDIO_HARDWARE_TRIGGERED_MODE where appropriate. - Add an attribute to configure device modes for quadrature counting etc. Clean ups and minor fixes * IIO core. - use __sysfs_match_string() helper rather than open coding the same. * ad7791 - use sysfs_match_string() helper rather than open coding the same. * aspeed-adc - handle return value of clk_prepare_enable * cpcap - Fix default register values and ensure the battery thermistor is enabled correctly. - Fix the reported die temperature where we can - docs are lacking. - Remove the hung interrupt quirk as no longer happens due to fix in the mfd driver. * hi8435 - Remove &s from hi8435_info definition as unneeded and inconsistent. * hid-sensor-trgger - Add kconfig depends on IIO_BUFFER (fixes patch in previous series) * ina2xx - Make the use of iio_info_mask* elements consistent for all channels. This doesn't have any visible effect, but acts as clear documentation of which channels various resulting attributes apply to. * lpc32xx - handle the return value of clk_prepare_enable. * meson-saradc - NULL instead of 0 for pointer. * mma9551 - use NULL for GPIO connection ID to aid implementation fo ACPI support. Here the connection ID doesn't actually tell us anything and it is much easier to deal with the driver if it's not there. * mpu6050 - Fix lock issues through use of a local mux. - Replace sprintf with scnprintf as appropriate. - Check whoami against all known values. This allows for a small number of boards where we are really fishing for the part not being present at all. It is unfortunately common to have undescribed changes to use newer chips. We paper over this but just emitting a warning for those cases as long as we know about. * mxs-lradc - Fix some non static warnings. * rcar-adc - Part of making the naming for this part consistent across the kernel. * st_accel - drop some spi_device_id entries for variants with no SPI support * st_magn - drop some spi_device_id entries for variants with no SPI support. * sx9500 - Use devm_gpiod_get instead of indexed value with an index of 0 on all occasions. * twl4030 - Drop unused twl4030_get_madc_conversion as callers removed now throughout kernel. - Unexport twl4030_madc_conversion() as no used only within this driver. - Drop twl4030_madc_user_params as not used now. - Drop twl4030_madc_request.func_cb as not used now. - Fold the twl4030-madc.h header into the driver as no longer used anywhere else in the kernel. * xilinx - Handle the return value of clk_prepare_enable

2017-06-13iio: imu: inv_mpu6050: test whoami first and against all known valuesJean-Baptiste Maneyrol1-9/+24
SPI bus is never generating error during transfer, so to check if a chip is correctly connected on a SPI bus we enforce whoami check to be correct. In this way we can assure SPI probe is failing if there is no chip connected. Note that this is really papering over boards that claim the device is there when it isn't. Not a bad thing to cope with, but not necessarily stable material.
