13   The Global Command Engine (GCE) is an instruction based, multi-threaded,
14   single-core command dispatcher for MediaTek hardware. The Command Queue
15   (CMDQ) mailbox driver is a driver for GCE, implemented using the Linux
16   mailbox framework. It is used to receive messages from mailbox consumers
17   and configure GCE to execute the specified instruction set in the message.
18   We use mediatek,gce-mailbox.yaml to define the properties for CMDQ mailbox
20   registers is a mailbox consumer. The mailbox consumer can request a mailbox
21   channel corresponding to a GCE hardware thread to send a message, specifying
22   that the GCE thread to configure its hardware. The mailbox provider can also
23   reserve a mailbox channel to configure GCE hardware register by the specific
24   GCE thread. This binding defines the common GCE properties for both mailbox
28   mediatek,gce-events:
30       GCE has an event table in SRAM, consisting of 1024 event IDs (0~1023).
32       The property mediatek,gce-events is used to obtain the event IDs.
33       Some gce-events are hardware-bound and cannot be changed by software.
35       send an event signal to GCE, setting the value of event ID 597 to 1.
38       On the other hand, some gce-events are not hardware-bound and can be
