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.
38 On the other hand, some gce-events are not hardware-bound and can be

42 is already bound to VDEC_LAT1, so we need to select another event ID to
43 achieve the same purpose. This event ID can be any ID that is not bound
44 to any hardware and is not yet used in any software driver.
45 To determine if the event ID is bound to the hardware or used by a
