Hi Jonathan,

Here it goes v2. Some points were still left open on v1 but this should
already include most of the things you asked for. 

---
Changes in v2:
- Link to v1: https://lore.kernel.org/r/[e-mail]

- Patch 1:
  * New patch;
  
- Patch 2:
  * Added IIO_BACKEND_NO_TESTPATERN to stop the pattern (may be a no-op);
  * Drop struct iio_backend_chan_status and use a bool pointer;
  * Rename tap -> taps;
  * Improved commit message.
  
- Patch 3 & 4:
  * Added fixes tag;
  * Imporved commit message (so one can better decide for backporting).

- Patch 6:
  * Add comment on the sleep before checking for error;
  * Use switch case in axi_adc_data_sample_trigger();
  * Add IIO_BACKEND_NO_TEST_PATTERN.

- Patch 7:
  * Instead of caching the sample_rate, use clk_get_rate() "in place";
  * Added comment clarifying dco (data clock output);
  * Remove shadow ret;
  * Moved the tuning table dump into debugfs.
