Jonathan writes: First set of IIO fixes for the 5.7 cycle. Includes one MAINTAINERS update to avoid people getting a lot of bounce messages and complaining about it. * MAINTAINERS - Drop Stefan Popa's Analog Devices email address in favour of Michael Hennerich. * core - Fix handling of dB sysfs inputs. - Drop a stray semi colon in macro definition. * ad5770r - Fix an off by one in chec on maximum number of channels. * ad7192 - Fix a null pointer de-reference due to the name previously being retrieved from the spi_get_device_id call which no longer works as the relevant table was removed. * ad7797 - Use correct attribute group. * counter/104-quad-8 - Add locks to prevent some race conditions. * inv-mpu6050 - Fix issues around suspend / resume clashing with runtime PM. * stm32-adc - Fix sleep in invalid context - Fix id relative path error in device tree binding doc. * st_lsm6dsx - Fix a read alignment issue on an untagged FIFO. - Handle odr for slave to properly compute the FIFO data layout / pattern. - Flush the HW FIFO before resettting the device to avoid a race on interrupt line 1. * st_sensors - Rely on ODR mask not ODR address to identify if the ODR can be set. Some devices have an ODR address of 0. * ti-ads8344 - Byte ordering was wrong - fix it. * xilinx-xadc - Fix inverted logic in powering down the second ADC. - Fix clearing interrupt when enabling the trigger. - Fix configuration of sequencer when in simultaneous sampling mode. - Limit initial sampling rate as done for runtime configured ones. * tag 'iio-fixes-for-5.7a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: MAINTAINERS: remove Stefan Popa's email iio: adc: ad7192: fix null pointer de-reference crash during probe iio: core: remove extra semi-colon from devm_iio_device_register() macro iio: adc: ti-ads8344: properly byte swap value iio: imu: inv_mpu6050: fix suspend/resume with runtime power iio: st_sensors: rely on odr mask to know if odr can be set iio: xilinx-xadc: Make sure not exceed maximum samplerate iio: xilinx-xadc: Fix sequencer configuration for aux channels in simultaneous mode iio: xilinx-xadc: Fix clearing interrupt when enabling trigger iio: xilinx-xadc: Fix ADC-B powerdown iio: dac: ad5770r: fix off-by-one check on maximum number of channels iio: imu: st_lsm6dsx: flush hw FIFO before resetting the device iio: core: Fix handling of 'dB' dt-bindings: iio: adc: stm32-adc: fix id relative path counter: 104-quad-8: Add lock guards - generic interface iio: imu: st_lsm6dsx: specify slave odr in slv_odr iio: imu: st_lsm6dsx: fix read misalignment on untagged FIFO iio: adc: stm32-adc: fix sleep in atomic context iio:ad7797: Use correct attribute_group

iio: core: remove extra semi-colon from devm_iio_device_register() macro

2020-04-19T16:50:02Z

This change removes the semi-colon from the devm_iio_device_register() macro which seems to have been added by accident.

iio: cros_ec: Use Hertz as unit for sampling frequency

2020-03-30T06:24:49Z

To be compliant with other sensors, set and get sensor sampling frequency in Hz, not mHz. Fixes: ae7b02ad2f32 ("iio: common: cros_ec_sensors: Expose cros_ec_sensors frequency range via iio sysfs") Signed-off-by: Gwendal Grignou Acked-by: Jonathan Cameron Signed-off-by: Enric Balletbo i Serra

iio: cros_ec: Report hwfifo_watermark_max

2020-03-28T21:04:33Z

Report the maximum amount of sample the EC can hold. This is not tunable, but can be useful for application to find out the maximum amount of time it can sleep when hwfifo_timeout is set to a large number.

iio: cros_ec: Expose hwfifo_timeout

2020-03-28T21:04:33Z

Expose EC minimal interrupt period through buffer/hwfifo_timeout: - Maximal timeout is limited to 65s. - When timeout for all sensors is set to 0, EC will not send events, even if the sensor sampling rate is greater than 0. Rename frequency to sampling_frequency to match IIO ABI. Signed-off-by: Gwendal Grignou Reviewed-by: Jonathan Cameron Signed-off-by: Enric Balletbo i Serra

iio: cros_ec: Remove pm function

2020-03-28T21:04:32Z

Since cros_ec_sensorhub is shutting down the FIFO when the device suspends, no need to slow down the EC sampling period rate. It was necesseary to do that before command CMD_FIFO_INT_ENABLE was introduced, but now all supported chromebooks have it.

iio: cros_ec: Register to cros_ec_sensorhub when EC supports FIFO

2020-03-28T21:04:32Z

When EC supports FIFO, each IIO device registers a callback, to put samples in the buffer when they arrives from the FIFO. When no FIFO, the user space app needs to call trigger_new, or better register a high precision timer.

iio: expose iio_device_set_clock

2020-03-28T21:04:32Z

Some IIO devices may want to override the default (realtime) to another clock source by default. It can beneficial when timestamps coming from the hardware or underlying drivers are already in that format. It can always be overridden by attribute current_timestamp_clock.
