2023-09-17iio: addac: stx104: Add 8254 Counter/Timer supportWilliam Breathitt Gray2-2/+60
The STX104 features an 8254 Counter/Timer chip providing three counter/timers which can be used for frequency measurement, frequency output, pulse width modulation, pulse width measurement, event count, etc. The STX104 provides a register bank selection to bank select between the 8254 Bank and the Indexed Register Array Bank; the Indexed Register Array is not utilized by this driver, so the 8254 Bank is selected unconditionally.

2023-09-13iio: ad4310: Replace devm_clk_register() with devm_clk_hw_register()Lars-Peter Clausen1-12/+3
The devm_clk_register() is deprecated and devm_clk_hw_register() should be used as a replacement. Switching to the clk_hw interface also allows to use the built-in device managed version of registering the clock provider. The non-clk_hw interface does not have a device managed version.

2023-09-13iio: addac: ad74413r: update channel function setAntoniu Miclaus1-0/+18
According to the datasheet switching to a new channel function implies multiple steps. All functions must be selected for a minimum of 130 μs before changing to another function. The DAC_CODEx registers are not reset by changing channel functions. Prior to changing channel functions, it is recommended to set the DAC code to 0x0000 via the DAC_CODEx registers. Set the channel function to high impedance via the CH_FUNC_SETUPx registers before transitioning to the new channel function. After the new channel function is configured, it is recommended to wait 150 μs before updating the DAC code. Even though the channel switch is done at only at probe, where a device reset is performed, that does not guarantee that the steps prior changing to new channel function should be neglected.

The delta velocity is defined as a piece-wise integration of acceleration data. The delta velocity represents the linear velocity change between two consecutive measurements and it is measured in m / s (meters per second). In order to track the total linear velocity change during a desired period of time, simply sum-up the delta velocity samples acquired during that time. IIO currently does not offer a suitable channel type for this type of measurements hence this patch adds it.

2023-09-11iio: adc: at91_adc: Use devm_clk_get_enabled() helper functionJinjie Ruan1-29/+9
