[PATCH v10 0/6] Add SPI offload support to AD4030

[Marcelo Schmitt]

Hello,

This is v10 of high speed data capture support for AD4030/AD4630 and similar ADCs.
It also adds support for ADAQ4216 and ADAQ4224.

Rebased on top of IIO testing.

Looks like a devm_pwm_get_disabled() interface might not get accepted so I
didn't change the handling of PWM initialization on v10.

Change log v9 -> v10
[DT]
- No changes.
[IIO]
- Explained the need of PWM in commint message.
- Fixed off-by-one bug.
- Use in-loop counter declaration.
- Correctly prepared patches, dropping unsupported bindings for input gain control.
- Skipped the patches applied from previous version.
- Initialize iio_scan_type struct fields on same order they are on structure definition.

Thanks,
Marcelo
