+ "mediatek,mt6779-gce".
- reg: Address range of the GCE unit
- interrupts: The interrupt signal from the GCE block
- clock: Clocks according to the common clock binding
- clock-names: Must be "gce" to stand for GCE clock
-- #mbox-cells: Should be 3.

phandle: Label name of a gce node.
channel: Channel of mailbox. Be equal to the thread id of GCE.
priority: Priority of GCE thread.
- atomic_exec: GCE processing continuous packets of commands in atomic
- way.
Required properties for a client device:
- mboxes: Client use mailbox to communicate with GCE, it should have this
property and list of phandle, mailbox specifiers.
