iio: adc: ad7173: add SPI offload support 

Merge series from David Lechner <dlechner@baylibre.com>:

Also there is a new dt-binding and driver for a special SPI offload
trigger FPGA IP core that is used in this particular setup.

other CPUs involved in the following operation attempts:



- Attempt to use CPU-local state to batch operations

- Attempt to fetch free nodes from global lists

- Attempt to fetch ``target_free`` free nodes from global lists

- Attempt to pull any node from a global list and remove it from the hashmap

- Attempt to pull any node from any CPU's list and remove it from the hashmap



The number of nodes to borrow from the global list in a batch, ``target_free``,

depends on the size of the map. Larger batch size reduces lock contention, but

may also exhaust the global structure. The value is computed at map init to

avoid exhaustion, by limiting aggregate reservation by all CPUs to half the map

size. With a minimum of a single element and maximum budget of 128 at a time.



This algorithm is described visually in the following diagram. See the

description in commit 3a08c2fd7634 ("bpf: LRU List") for a full explanation of

the corresponding operations:
