Robert Jördens 307cd07b9d suservo: lots of gateware/ runtime changes 
tested/validated:

* servo enable/disable

* profile configuration (coefficients, delays, offsets, channel)
* adc timings and waveforms measured
* asf state readback
* adc readback

individual changes below:

suservo: correct rtio readback

suservo: example, device_db [wip]

Robert Jördens 01f762a8f5 urukul/ad9910: support blind init 
urukul: always set io_update attribute
to silence compiler warning w.r.t. kernel_invariants

Robert Jördens edbc7763e0 urukul: allow no io_update_device 2018-04-25 17:32:36 +00:00
Sebastien Bourdeauducq c47d3ec8c8 zotino: use None as default for ldac and clr 
This is also what AD53xx does.

whitequark 3b054855ec firmware: add allocator debug feature, invoked by artiq_coredebug frontend. 2018-04-21 19:39:46 +00:00
Sebastien Bourdeauducq 5ca59467fd ad53xx: make LDAC and CLR optional 2018-03-26 22:45:01 +08:00
Robert Jördens a8f0ee1c86 ad53xx: refactor offset_to_mu(), fix docs 2018-03-24 15:45:42 +01:00
Robert Jördens b0c8097025 ad53xx: remove channel index AND 
It's incorrect since it doesn't respect the number of channels
of any of those chips (none has 64 channels).

Robert Jördens 77bcc2c78f zotino: style, use attributes to set SPI config 2018-03-24 15:37:34 +01:00
Robert Jördens 2cf414a480 ad53xx: move 8 bit shift out of ad53xx protocol funcs 
That's specific to the SPI bus, not to the ad53xx.

hartytp a992a672d9 coredevice/zotino: add (#969) 
* Replace ad5360 driver with a ad53xx driver, designed to have a nicer interface
Add Zotino driver and add to opticlock target for Kasli
Test Zotino on hw:
 - Verify all timings on the hardware with a scope
 - Verify that we can correctly set and read back all registers in a loop (checks for SI and driver issues)
 - check we can set LEDs correctly
 - check calibration routine + all si unit functions with a good DVM
 - look at DAC transitions on a scope (while triggering of a TTL) on persist to check there are no LDAC glitches etc
To do: update examples and e.g. KC705 device db.

Robert Jördens f17c0abfe4 urukul: don't pulse DDS_RST on init

Apparently, if the DDS are reset, every other time they don't work
properly.
