AD9213 driver

[danmois]

PR Description

The AD9213 is a single, 12-bit, 6 GSPS/10.25 GSPS, radio frequency (RF) analog-to-digital converter (ADC) with a 6.5 GHz input bandwidth. The AD9213 supports high dynamic range frequency and time domain applications requiring wide instantaneous bandwidth and low conversion error rates (CER). The AD9213 features a 16-lane JESD204B interface to support maximum bandwidth capability.

Please look at my comment about commit subjects in the first version of the series. Also, can we have this without JESD FSM? What I'm thinking is to upstream the driver without FSM and then backport it with it. At least, the driver would not be completely out of tree

I doubt that this can be done without the FSM. It assures that the correct probing order is maintained. Will experiment if removing it is possible.

Yeah, it would be just so we could upstream a version of the driver without it :)
