[PATCH v7 0/8] Add SPI offload support to AD4030
Posted by Marcelo Schmitt 1 day, 18 hours ago
Hi,

This set add high speed data capture with AD4030/AD4630 and similar ADCs. It
also adds support for ADAQ4216 and ADAQ4224.

Quick recap, this set was extensively reviewed but was put on hold due to the
need of updates to the HDL project associated with these devices. Now that the
HDL project has been updated and retested, I believe we can have the driver
updates added to the IIO tree.

Change log v6 -> v7
[DT]
- No changes. 
[IIO]
- Dropped unneeded enter/exit reg config mode, simplifying offload buffer setup procedures.

Tested with ADAQ4216 on ZedBoard.

Thanks,
Marcelo

Hi Marcelo

Just a quick note to say I took another look through and what I spotted
was a subset of stuff Andy already pointed out.

Given this is now next cycle material anyway, please just tidy those
bits up in a v8 and I'll get this queued up.

Thanks,

Jonathan
