Subject: [PATCH 08/16] dt-bindings: imx: gpcv2: add support for optional resets

From: Lucas Stach <l.stach@...gutronix.de>

For some domains the resets of the devices in the domain are not
automatically triggered. Add an optional resets property to allow
the GPC driver to trigger those resets explicitly.
