7 title: Mediatek ADSP mailbox
10 - Allen-KH Cheng <Allen-KH.Cheng@mediatek.com>
13 The MTK ADSP mailbox Inter-Processor Communication (IPC) enables the SoC
14 to communicate with ADSP by passing messages through two mailbox channels.
15 The MTK ADSP mailbox IPC also provides the ability for one processor to
16 signal the other processor using interrupts.
