[PATCH v6 0/8] Add SPI offload support to AD4030

[Marcelo Schmitt <marcelo.schmitt@analog.com>]

Hi,

Thanks for all reviews and suggestions to v5.
I believe to have addressed them all and here comes v6.

Change log v5 -> v6
[DT]
- Picked up Conor's review tag.
[IIO]
- Adjusted comment on list of average modes.
- Dropped link associated with Suggested-by tag.
- Fixed IIO device number of channels in base offload support patch for AD4030.
- Dropped st->offload_trigger check in paths only reachable with offload support.
- Adjusted comment about sample averaging and sampling frequency configurations.
- Dropped redundant parentheses on declaration of ADAQ hw gain table.
- Dropped unneeded cast to u64.
- Use constant for number of ADAQ PGA pins in error message.
- Picked up review tags.
- Re-added common-mode channel for offload setups in a separate patch.

There is a patch to the SPI subsystem [1] that contains a feature required by
AD4030 offload support.

When that patch become available in an immutable branch or similar, I'll gladly
rebase this series on top of that.

Thanks,
Marcelo
