yaml: rtc: Add yaml definitions for RTC This patch adds the YAML descriptions for a generic RTC block and also for NXP Kinetis based RTCs. Signed-off-by: Andy Gross <agross@kernel.org>

drivers: counter: update counter_mcux_rtc.c Set LPO 1KHZ clock for RTC if clock source 'LPO' is selected. The frdm_ke17z512 has no 32KHZ OSC, the RTC clock comes from SOSC, RTC_CLKIN, LPO 1KHZ. But usually the SOSC is connected with 8MHZ oscilator, so only 1kHZ LPO is usable. Update the nxp,kinetis-rtc.yaml to select RTC clock source. Signed-off-by: Anke Xiao <anke.xiao@nxp.com>

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.

dts: bindings: Remove 'title:' and put all info. into 'description:' Add any useful information from 'title:' to the 'description:' strings (e.g. explanations of acronyms), and remove 'title:' as well as any copy-pasted "this binding gives a ..." boilerplate. Also clean some description strings up a bit. Some other things could probably be cleaned up (replacing 'GPIO node' with 'GPIO controller' on controllers for consistency, for example), but I kept things close to the original to avoid accidentally messing up.

scripts: dts: Simplify and improve 'compatible' matching Instead of properties: compatible: constraint: "foo" , just have compatible: "foo" at the top level of the binding. For backwards compatibility, the old 'properties: compatible: ...' form is still accepted for now, and is treated the same as a single-element 'compatible:'. The old syntax was inspired by dt-schema (though it isn't dt-schema-compatible), which is in turn a thin wrapper around json-schema (the idea is to transform .dts files into YAML and then verify them). Maybe the idea was to gradually switch the syntax over to dt-schema and then be able to use unmodified dt-schema bindings, but dt-schema is really a different kind of tool (a completely standalone linter), and works very differently from our stuff (see schemas/dt-core.yaml in the dt-schema repo to get an idea of just how differently). Better to keep it simple. This commit also piggybacks some clarifications to the binding template re. '#cells:'. Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>

clock-source:
type: string
default: "RTC"
enum:
- "RTC"
- "LPO"
description: |
Select one of two possible clock sources for the RTC:
* RTC: RTC prescaler increments using RTC clock.
* LPO: RTC prescaler increments using 1 kHz LPO.
The default corresponds to the reset value of the register field,
and there is no additional code configuration in the driver.
