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_nor: remove configurability of page/sector/block sizes The JEDEC API defines the hardware page, sector, and block sizes. Deprecate the Kconfig settings, remove the `erase-size-block` property, and add `has-be32k` to indicate that 32K-byte erase is supported. Rework the driver to use the constants instead of configured values. Signed-off-by: Peter A. Bigot <pab@pabigot.com>

dts: flash: add missing DT properties to jedec,spi-nor The erase-block-size and write-block-size are needed for the spi_nor driver to compile. scripts/dts/extract/flash.py automatically adds these properties if this flash device is part of the "chosen" flash node, but they're otherwise missing.
