[PATCH 2/8] dt-bindings: clock: stm32mp1: describes clocks if "st,stm32mp1-rcc-secure"

[Alexandre Torgue <alexandre.torgue@xxxxxxxxxxx>]

In case of "st,stm32mp1-rcc-secure" (stm32mp1 clock driver with RCC
security support hardened), "clocks" and "clock-names" describe oscillators
and are required.
