Subject[PATCH v5 1/6] dt-bindings: mfd: Document STM32 low power timer bindings
Date
Add a subnode to STM low power timer bindings to support timer driver

Signed-off-by: Benjamin Gaignard <benjamin.gaignard@st.com>
---
version 5:
- the previous has been acked-by Rob but since I have docummented
interrupts and interrupt-names properties I haven't applied it here.

version 4:
- change compatible and subnode names
- document wakeup-source property
