In this series we add devicetree bindings and an IIO driver with support for triggered buffer and events. Link to the datasheet should be added to the devicetree bindings, when that is available. Changes in v4: [iio] * Use `iio_trigger_poll_nested()` instead of `iio_trigger_poll_chained()`. (Remnant from old tree... Sorry!) Link to v3: https://lore.kernel.org/lkml/cover.1689683411.git.waqar.hameed@axis.com/ Changes in v3: [dt-bindings] * Add "Reviewed-by" footer in commit message. [iio] * Use `__le16` for buffers in `regmap_bulk_read/write()`. * Use `8` instead of `BIT(3)` in `irsd200_write_nr_count()`. * Rename `val` to `tmp` in `irsd200_write_event_config()`. * Return `0` on success in `irsd200_write_event_config()`. * Return `IRQ_HANDLED` instead of `IRQ_NONE` in error paths. * Return `IRQ_NONE` when not clearing anything in `irsd200_irq_thread()`. * Use `devm_regulator_get_enable()` in probe. Link to v2: https://lore.kernel.org/lkml/cover.1689174736.git.waqar.hameed@axis.com/ Changes in v2: [dt-bindings] * Remove "bindings for" in commit subject. * Remove superfluous yaml block style indicator ('|') for `description:`. * Change node name in example from `pir` to `proximity`. * Add required `vdd-supply` property. [iio] * Add event enums for running period and count. * Use `set_trigger_state` callback instead of `iio_buffer_setup_ops`'s `predisable` and `postenable`. * Use `regmap_bulk_read()` in `irsd200_read_data()` and `irsd200_read_timer()`. * Use `regmap_bulk_write()` in `irsd200_write_timer()`. * Remove comment for macro `IRS_UPPER_COUNT()`. * Move `IIO_EV_INFO_LOW/HIGH_PASS_FILTER_3DB` from `iio_event_spec` to `iio_chan_spec`. * Ignore timer (`IRS_INTR_TIMER`) interrupts. * Clarify comment on `ssleep(3)` in `irsd200_write_data_rate()`. * Only check for non-zero return values from `regmap` functions (as opposed to `ret < 0`). * Add macro defines for operation states. * Remove fix size in static const array declarations. * Remove unnecessary `ret` variable in `irsd200_write_raw()`. * Remove comments in `irsd200_event_spec[]`. * Remove unnecessary call to `i2c_set_clientdata()` in probe. * Use `dev_err_probe()` everywhere in probe. * Remove unnecessary braces around if statement in probe. * Get and enable regulator in probe.
