19 typically used in pairs-one for receiving and one for transmitting.
22 channel 0-7 - Fast channel with 32bit transmit register and IRQ support
23 channel 8 - Doorbell mode,using the mailbox as an interrupt-generating
25 channel 9 - Fifo based channel with 32*32bit depth fifo and IRQ support
26 channel 10 - Reg based channel with 32*32bit transmit register and
29 In the CIX Sky1 SoC use case, there are 4 pairs of mailbox controllers
30 AP <--> PM - using Doorbell transfer mode
31 AP <--> SE - using REG transfer mode
32 AP <--> DSP - using FIFO transfer mode
33 AP <--> SensorHub - using FIFO transfer mode
