7 title: TI OMAP2+ and K3 Mailbox devices
10 - Suman Anna <s-anna@ti.com>
13 The OMAP Mailbox hardware facilitates communication between different
14 processors using a queued mailbox interrupt mechanism. The IP block is
19 Each mailbox IP block/cluster has a certain number of h/w fifo queues and
35 lines can also be routed to different processor sub-systems on DRA7xx as they
