spi: sam0: use Device Tree for configuration. Switch the SoC device tree to define a single entry per SERCOM instead of one per mode. Define a Device Tree binding for the SAM0 SPI and use it instead of Kconfig for enabling / disabaling instances Switch the Arduino Zero, Adafruit Feather M0 Basic Proto, and Trinket M0 to use the new defintion. Add the APA102 LED that's on the Trinket as a test. Signed-off-by: Michael Hope <mlhx@google.com> Signed-off-by: Kumar Gala <kumar.gala@linaro.org>

yaml: Remove redundant document separators YAML document separators are needed e.g. when doing $ cat doc1.yaml doc2.yaml | <parser> For the bindings, we never parse concatenated documents. Assume we don't for any other .yaml files either. Having document separators in e.g. base.yaml makes !include a bit confusing, since the !included files are merged and not separate documents (the merging is done in Python code though, so it makes no difference for behavior). The replacement was done with $ git ls-files '*.yaml' | \ xargs sed -i -e '${/\s*\.\.\.\s*/d;}' -e 's/^\s*---\s*$//' First pattern removes ... at the end of files, second pattern clears a line with a lone --- on it. Some redundant blank lines at the end of files were cleared with $ git ls-files '*.yaml' | xargs sed -i '${/^\s*$/d}' This is more about making sure people can understand why every part of a binding is there than about removing some text.

drivers: spi: sam0: Implement DMA async API This adds support for the async API for SAM0 SERCOM SPI using DMA to drive the device. This implementation does the reload for both transmit and receive in the receive DMA handler. Doing this simplifies the implementation but means that the transmit drains completely, resulting in the SPI clock pausing between buffers while both are reloaded in the receive handler. Tested with tests/drivers/spi/spi_loopback and several simple programs monitored with a logic analyzer. Signed-off-by: Derek Hageman <hageman@inthat.cloud>
