Cover letter [Industrial I/O] [0/13] RFC: Maxim MAX1363 driver (ring buffer support)

From: Jonathan Cameron <[email protected]>

IIO: Maxim MAX1363 driver (ring buffer support)

Signed-off-by Jonathan Cameron <[email protected]>

--
This patch adds triggered software ring buffer support to the core driver. It should act as an example of how many of the elements of the IIO subsystem function.

There is currently an issue with unaligned timestamps on arm to be resolved when non multiple of 4 scan modes used.
