Subject: [PATCH 2/3] Documentation/process: maintainer-soc: add clean platforms profile

Some SoC platforms require that commits must not bring any new
dtbs_check warnings.  Maintainers of such platforms usually have some
automation set, so any new warning will be spotted sooner or later.
Worst case: they run the tests themselves.  Document requirements for
such platforms, so contributors can expect their patches being dropped
or ignored, if they bring new warnings for existing boards.

+=============================
+SoC Platforms with Strict DTS
+=============================
+
+Overview
+--------
+
+SoC platforms or subarchitectures follow all the rules from
+Documentation/process/maintainer-soc.rst.  However platforms referencing this
+document impose additional requirements listed below.
+
+Strict DTS DT schema compliance
+-------------------------------
+None of the changes to the SoC platform Devicetree sources (DTS files) can
+bring new ``make dtbs_check W=1`` warnings.  The platform maintainers have
+automation in place which should point out any new warnings.
+
+If a commit introducing new warning gets accepted somehow, the resulting issues
+shall be fixed in reasonable time (e.g. within one release) or the commit
+reverted.
