* iio: addac: stx104: Replace bitops.h header inclusion with bits.hWilliam Breathitt Gray2023-03-191-1/+1
| | | | | | | | | | | The <linux/bitops.h> header is included in the stx104 driver so that we can use the BIT() macro. This macro is actually defined in the <linux/bits.h> header, so replace the <linux/bitops.h> header inclusion with <linux/bits.h>.

* iio: dac: cio-dac: Migrate to the regmap APIWilliam Breathitt Gray2023-03-182-21/+46
| | | | | | | | | | | | | The regmap API supports IO port accessors so we can take advantage of regmap abstractions rather than handling access to the device registers directly in the driver. Includes trivial header inclusion tidy up.

| | | | | | | | | | | | Make use of devm_clk_get_enabled() to replace some code that effectively open codes this new function. To retain ordering move the request to a place that is executed later. This way the time of enable keeps the same.

Introduce the capability to drop a given number of samples according to the configured ODR. Add sample_to_discard for LSM6DSM-like sensors since new generation devices (e.g. LSM6DSO) support DRDY mask where corrupted samples are masked in hw with values greather than 0x7ffd so the driver can easily discard them. I have not added sample_to_discard support for LSM6DS3 or LSM6DS3H since I do not have any sample for testing at the moment.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver supports 4 chips, by which only one (vcnl4010) handles interrupts and has support for triggered buffer. The setup of these functions is hardcoded for vcnl4010 inside the generic vcnl4000_probe, and thus ignores the chip specific configuration structure where all other chip specific functions are specified. This complicates adding interrupt handler and triggered buffer support to chips which may have support for it. Add members for irq threads and iio_buffer_setup_ops to the generic vcnl4000_chip_spec struct, so that instead of checking a chip specific boolean irq support, we check for a chip specific triggered buffer handler, and/or a chip specific irq thread handler.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to allow the chip_spec array reference the function pointers for interrupts, the code for these functions need to be moved above the chip_spec array. This is a prestep to support a more generic setup of interrupts.
