Data	Data does not need to include mailbox property channel header or footer. Data pointer does not need any specific alignment or caching attributes.
Size	Size must be a multiple of 4 bytes. Size must include the size of the request and response which use the same buffer.

Cycles	Number of cycles after which the timer interrupt is to be triggered
Note	This refers to native clock cycles as specified by CLOCK_FREQUENCY

Cycles	Number of cycles after which the scheduler interrupt is to be triggered
Note	This refers to native clock cycles as specified by RPI2_GENERIC_TIMER_FREQUENCY
