-Dependency on driver component shall be explicit

+Component dependencies that shall be explicit
+---------------------------------------------
 
-In previous versions of ESP-IDF, target components (``components/esp32*``) had a dependency on ``driver`` component. Since target components were part of common requirements (:ref:`more info about common requirements <component-common-requirements>`), all components in the project implicitly had a dependency on ``driver`` component. Now that the dependency of target components on ``driver`` has been removed, every component which depends on ``driver`` has to declare this dependency explicitly. This can be done by adding ``REQUIRES driver`` or ``PRIV_REQUIRES driver`` in ``idf_component_register`` call inside component's ``CMakeLists.txt``. See :ref:`Component Requirements` for more information on specifying component requirements.
