Subject: [PATCH v3 0/1] Add SPI offload trigger offset

Add SPI offload offset parameter needed to achieve high sample rates with ADCs
that require some synchronization between a conversion start signal and the issue
of data transfers.

Change log v1 -> v2
- Using upper case: adc -> ADC.
- Codestyle/readability improvements according to suggestions.

Change log v2 -> v3
- Squashed SPI offload trigger commits.
- Added documentation to offload trigger periodic parameters.
- Picked up reviewed-by tags.

The updates to the ADC driver that use these changes proposed to the SPI
subsystem will go in a patch set titled 'Add SPI offload support to AD4030'.
