The function activity_event_en() configures the generic interrupts
GEN1 and GEN2, which are used for activity and inactivity detection
as per the datasheet. The existing name is misleading, since the
device also provides activity change and activity recognition
interrupts. Activity change interrupt is not supported yet whereas
Activity recognition interrupt is configured in a different function.
Rename activity_event_en() to generic_event_en() to better reflect its
actual purpose.
No functional changes intended.

set_* functions involve left shift of param values into respective
register fields before writing to register. Similarly get_* functions
involve right shift to extract values from the respective bit fields.
Replace these explicit shifting statements with standard kernel style
macros FIELD_GET() and FIELD_PREP().

Introduce formula-based macros to compute GEN INTR configuration register
addresses from the interrupt number and register index. This reduces the
need for 22 explicit register macros to three base definitions.
Add a centralized lookup table keyed by IIO event direction and replace
get_gen_config_reg() with a helper integrated with this table.
Apply these changes across the affected callbacks to ensure consistent
access to generic interrupt registers.
No functional changes are intended.

Reorganize register and field macros to improve consistency with the
datasheet and naming style:
- Move field macros next to their corresponding register macros
- Reorder register macros to follow address order from the datasheet
- Rename field macros to include the register name in the macro name
- Add a _REG suffix to register macros where missing
- Add INT_STAT register fields corresponding to used INT_CONFIG fields
No functional changes are intended.

The required LED pulse width depends on board-specific optical and
mechanical design, which affects measurement accuracy and power use.
Making it configurable via Device Tree allows each platform to define
an appropriate value instead of relying on a hardcoded default.
If unspecified, the driver defaults to 1600 us for backward compatibility.
Tested on: Raspberry Pi 3B + MAX30100 breakout board.

The error code returned from devm_iio_trigger_register() inturn
iio_trigger_register() can be other than -ENOMEM. Hence return the

Add support for AD4081 20-bit SAR ADC. The AD4081 has the same
resolution as AD4080 (20-bit) but differs in LVDS CNV clock count
maximum (2 vs 7).
Changes:
- Add AD4081_CHIP_ID definition (0x0051)
- Create ad4081_channel with 20-bit resolution and 32-bit storage
- Add ad4081_chip_info with lvds_cnv_clk_cnt_max = 2

Refactor the ad4080 driver to support multiple ADC variants with
different resolution bits and LVDS CNV clock count maximums.
Changes:
- Add lvds_cnv_clk_cnt_max field to chip_info structure
- Create AD4080_CHANNEL_DEFINE macro for variable resolution/storage bits
- Make LVDS CNV clock count configurable per chip variant
- Use chip_info->product_id for chip identification comparison
This prepares the infrastructure for adding support for additional
ADC parts with different specifications while maintaining backward
compatibility with existing AD4080 functionality.

Fix AD4080 chip identification by using the correct 16-bit product ID
(0x0050) instead of GENMASK(2, 0). Update the chip reading logic to
use regmap_bulk_read to read both PRODUCT_ID_L and PRODUCT_ID_H
registers and combine them into a 16-bit value.
The original implementation was incorrectly reading only 3 bits,
which would not correctly identify the AD4080 chip.

Add support for the A/D 12-Bit successive approximation converters found
in the Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs.
RZ/T2H has two ADCs with 4 channels and one with 6.
RZ/N2H has two ADCs with 4 channels and one with 15.
Conversions can be performed in single or continuous mode. Result of the
conversion is stored in a 16-bit data register corresponding to each
channel.
The conversions can be started by a software trigger, a synchronous
trigger (from MTU or from ELC) or an asynchronous external trigger (from
ADTRGn# pin).
Only single mode with software trigger is supported for now.
