1. Simplify the control logic by adding a state machine.
The improvements are on code readability and reliability.
2.Add a flush feature which can be used to clean the data from the DMA fifo.
This is useful when the DMA is programmed in cyclic mode and
data transmission is stopped by dma_transfer_suspend flag
The software intervention is reduced at setting the flag(dma_flush_en).
Flushing can also be done when activating the raw value with dma_flush_en active.
3. Add raw value support. Through this changes a user can set
the dac output to a fixed predefined value in the following two cases:
1. direct, without using the dma.
2. with dma, as a hold value. The fixed value will be kipped after a cyclic
buffer is stopped by axi_dac_interpolate, through dma_transfer_suspend
register/signal.
The raw value ca be set and transmitted independently on each channel.
The predefined value is stored in reg 0x19(0x64). For more details se
the documentation available at
https://wiki.analog.com/resources/fpga/docs/axi_dac_interpolate
axi_dac_interpolate - Remove last sample hold control
axi_ad9963 - Remove last sample hold control and set as default the
last sample hold functionality plus code optimization changes.
This commit introduces a different interface to submit transfers, using
DMA descriptors.
The structure of the DMA descriptor is as follows:
struct dma_desc {
u32 flags,
u32 id,
u64 dest_addr,
u64 src_addr,
u64 next_sg_addr,
u32 y_len,
u32 x_len,
u32 src_stride,
u32 dst_stride,
};
The 'flags' field currently offers two control bits:
- bit 0: if set, the transfer will complete after this last descriptor
is processed, and the DMA core will go back to idle state; if cleared,
the next DMA descriptor pointed to by 'next_sg_addr' will be loaded.
- bit 1: if set, an end-of-transfer interrupt will be raised after the
memory segment pointed to by this descriptor has been transferred.
The 'id' field corresponds to an identifier of the descriptor.
The 'dest_addr' and 'src_addr' contain the destination and source
addresses to use for the transfer, respectively.
The 'x_len' field contains the number of bytes to transfer,
minus one.
The 'y_len', 'src_stride' and 'dst_stride' fields are only useful for
2D transfers, and should be set to zero if 2D transfers are not
required.
To start a transfer, the address of the first DMA descriptor must be
written to register 0x47c and the HWDESC bit of CONTROL register must
be set. The Scatter-Gather transfer is queued similarly to the simple
transfers, by writing 1 in TRANSFER_SUBMIT.
The Scatter-Gather interface has a dedicated AXI-MM bus configured for
read transfers, with its own dedicated clock, which can be asynchronous.
The Scatter-Gather reset is generated by the reset manager to reset the
logic after completing any pending transactions on the bus.
When the Scatter-Gather is enabled during runtime, the legacy cyclic
functionality of the DMA is disabled.

* SPI Engine: Add execution delay documentation
Add documentation for the different delays on the command path and

execution overhead.

* docs: Improve consistency
The following rules have been implemented:
1. Tables/lists should contain only the carriers that we support for
that reference design.
2. Hexadecimal addresses should be written in caps and separated
by an underscore (eg. 0x9C4A_0000).
3. Block diagrams should contain subtitles only if there are at
least two different diagrams.
4. The GPIOs should be listed in descending order and should have
the number of bits specified next to their name.
5. All the source code links references should contain the project
name.
6. The infrastructure documentation, if exists, should be listed
after the IP list.
* The version is set to be 23.2.0 because this is what Quartus returns
as value when running the --version command
* Still, Quartus has as installation path "intelFPGA_pro/23.2" and not
the version which contains an additional ".0"

Recommend storing images like any other artifact: in a hierarchical
manner, without "images" subfolders.
This is intended to avoid dangling artifacts when projects are moved,
renamed, or deleted.
Recommend overwriting the page title with a shorter title in the
toctree, so the navigation bar doesn't overflow or get too cluttered.
Add acostina to CODEOWNERS

Drop part role, use generic adi instead for root adi domain links.
For future reference, the snipped used was:
find ./docs/projects -type f -exec sed -i 's/:part:/:adi:/g' {} \;
Drop Containerfile.
Add option to validate links status (e.g. 200, 404), intended mostly for CI
use to check if a page has disappeared from the internet.
Validate links uses coroutines to launch multiple tasks concurrently,
but do it in bundles to avoid being rate limited.
Fixup regmap styling.
Add imoldovan, jmarques, spop, lbarbosa as docs codeowners.
Remove branch field for links to the hdl repo.

Fixed wrong behaviour on chip select instruction:
- previously, a sleep time happened before the chip select change
- the intended behaviour was for another sleep time, of equal amount, to happen after the chip select change as well
- additionally, the counter logic implementation was creating an additional factor of 2 on the sleep time
All of the above points were fixed. The changes introduced also fix another issue where the sleep instruction was likewise happening with a duration larger than intended by a factor of 2
