      iio: adc: stm32: add dt option to set resolution · 25a85bed
      Fabrice Gasnier authored
      stm32 adc supports several resolution. Add 'assigned-resolution-bits'
      dt optional property to set it. Default to maximum resolution in case
      it isn't set.

      Merge tag 'iio-for-4.12c' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
      
      Third set of new device support, cleanups and features for IIO in the 4.12 cycle
      
      Somewhat dominated in patch numbers of last of the outreachy application
      window related patches (they are still coming, despite window being closed
      which is good to see!)
      
      Good set of new drivers as well.
      
      New device support
      * ASPEED ADC
        - new driver
      * cpcap PMIC ADC
        - new driver
      * hid-humidity
        - driver for HID compatible humidity sensors.
      * ltc2497 ADC
        - new driver
      * mpu6050
        - bring bindings up to date and add trivial support for 9250
      * rockchip-saradc
        - update bindings to cover rk3328
      * vl6180 light, proximity and time of flight sensor.
        - new driver
      
      Features
      * meson-saradc
        - add calibration
      
      Cleanup and minor fixes
      * ad5504
        - constify attribute_group structure
        - drop casting of void *
      * ad7150
        - replace some shifts of 1 by BIT macro usage
      * ad7152
        - blank lines between function definitions
      * ad7280a
        - octal permissions.
      * ad7606
        - replace use of core mlock mutex with a local lock
      * ad7746
        - replace some shifts of 1 by BIT macro usage
        - function parameter alignment
        - drop some excessive brackets (introduced in last pull request)
      * ad7753
        - white space cleanup
      * ad7754
        - includes in alphabetical order and groupped appropriately.
        - change from missuse of internal mlock mutex to using the buffer lock to
        also protect values during frequency update.
      * ad779x
        - constify attribute_group structures
      * ad9832
        - octal permissions
      * adis16060
        - remove use of core mlock mutex in favour of adding a local
        _spi_write_then_read which can use the local buffer protection lock.
        - fix naming of above function.
      * adis16203
        - remove locking during reads of calibbias that doesn't protect anything
        not protected elsewhere.

      iio: adc: cpcap: Add minimal support for CPCAP PMIC ADC · 25ec2496
      Tony Lindgren authored
      On Motorola phones like droid 4 there is a custom CPCAP PMIC. This PMIC
      has ADCs that are used for battery charging and USB PHY VBUS and ID pin
      detection.
      
      Unfortunately the only documentation for this ADC seems to be the
      Motorola mapphone Linux kernel tree. I have tested that reading raw and
      scaled values works, but I have not used the timed sampling that the ADC
      seems to support.
      
      Let's add a minimal support for it so we can eventually provide IIO
      channels for the related battery charging and USB PHY drivers.
