Subject: [PATCH] dt-bindings: mfd: stm32-timers: Document how to specify
 interrupts
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

The timer units in the stm32mp1 CPUs have interrupts, depending on the
timer flavour either one "global" or four dedicated ones. Document how
to formalize these in a device tree.
