Subject: [PATCH 05/15] spi: offload: types: add offset parameter

From: Axel Haslam <ahaslam@...libre.com>

Add an offset parameter that can be passed in the periodic trigger.
This is useful for example when adc drivers implement a separate periodic
signal to trigger conversion and need offload to read the result with
some delay.
