Subject: [PATCH 02/16] dt-bindings: soc: renesas: renesas,rzg2l-sysc: Add #reset-cells for RZ/G3S

From: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>

The RZ/G3S System controller has registers to control signals that need
to be de-asserted/asserted before/after different SoC areas are power
on/off. This signals are implemented as reset signals. For this document
the #reset-cells property.
