Murata IRS-D200 is a PIR sensor for human detection. It has support for raw data measurements and detection event notification. Add a driver with support for triggered buffer and events. Map the various settings to the `iio` framework, e.g. threshold values, sampling frequency, filter frequencies etc. Signed-off-by:

There are devices (such as Murata IRS-D200 PIR proximity sensor) that check the data signal with a running period. I.e. for a specified time, they count the number of conditions that have occurred, and then signal if that is more than a specified amount. `IIO_EV_INFO_PERIOD` resets when the condition no longer is true and is therefore not suitable for these devices. Add a new `iio_event_info` `IIO_EV_INFO_RUNNING_PERIOD` that can be used as a running period. Also add a new `IIO_EV_INFO_RUNNING_COUNT` that can be used to specify the number of conditions that must occur during this running period. Signed-off-by:

min() has strict type checking and preferred over min_t() for unsigned types to avoid overflow. Here it's unclear why min_t() was chosen since both variables are of the same type. In any case update to use min(). Signed-off-by:

Define and init voltage configuration bits. Those bits are inited in vendor boot code (bl2, bl33) already so do it in the driver to not depend on other code. Introduced bits: REG11[0] - selects Vref. 0 - calibration voltage, 1 - VDDA. txlx and later SoCs support VDDA or calibration voltage as Vref, but others support only calibration voltage. For newer platforms vendor uses VDDA as default. REG11[1] - reserved bit. g12a and later SoCs must write 1, others SoCs write 0. REG11[5] - Vref voltage. 0 - 0.9v, 1 - 1.8v. g12a and later SoCs must write 0, others SoCs write 1. REG11[6] - selects common-mode voltage, 0: from AVDD, 1: from Vref. g12a and later SoCs must write 0, others SoCs write 1.

Enable buffered reading of samples from the LMP92064 ADC. The main benefit of this change is being able to read out current and voltage measurements in a single transfer, allowing instantaneous power measurements. Reads into the buffer can be triggered by any software triggers, e.g. the iio-trig-hrtimer: $ mkdir /sys/kernel/config/iio/triggers/hrtimer/my-trigger $ cat /sys/bus/iio/devices/iio\:device3/name lmp92064 $ iio_readdev -t my-trigger -b 16 iio:device3 | hexdump WARNING: High-speed mode not enabled 0000000 0000 0176 0101 0001 5507 abd5 7645 1768 0000010 0000 016d 0101 0001 ee1e ac6b 7645 1768 ...

When processing data read the full fifo data in 1 time. If there are several samples in the FIFO, it means we are experiencing system delay. In this case, it is better to read all data with 1 bus access than to add additional latency by doing several ones. This requires to use a bigger buffer depending on chip FIFO size and do an additional local data copy before sending. But the cost is minimal and behavior is still better like this under system heavy load. Signed-off-by:

The General Purpose ADC (GPADC) can convert the external signal into a certain proportion of digital value, to realize the measurement of analog signal, which can be applied to power detection and key detection. Theoretically, this ADC can support up to 16 channels. All SoCs below contain this GPADC IP. The only difference between them is the number of available channels: T113 - 1 channel D1 - 2 channels R329 - 4 channels T507 - 4 channels Reviewed-by:

Add the proximity multi pulse (PS_MPS) as oversampling_ratio. Instead of one single pulse per every defined time frame, one can program2, 4, or even 8 pulses. This leads to a longer IRED on-time for each proximity measurement value, which also results in a higher detection range. Add read/write attribute for proximity oversampling-ratio and read attribute for available oversampling-ratio. This is supported for vcnl4040 and vcnl4200. Signed-off-by:

Add read/write attribute for proximity and illuminance period. The period is set in the interrupt persistence flags(PS_PERS and ALS_PERS). An interrupt will not be asserted if the raw value is not over (or lower) than the threshold for the set continued amount of measurements. The time in seconds is calculated by the number of continued refreshes multiplied with the integration time. It will always pick the next lower possible value. The period changes, if the integration time is changed. Signed-off-by:
