[PATCH 0/2] Enable Mailboxes for AM57xx IDKs

[PATCH 0/2] Enable Mailboxes for AM57xx IDKs

[Suman Anna]

Hi Tony,

This series enables the mailbox nodes to be used for communicating with
the DSPs and IPUs on AM57xx IDKs using IPC 3.x. The mailbox nodes themselves
were already defined/added before for other DRA7 boards, and these patches
simply enable the respective nodes for the IDKs.

Patches are based on 4.12-rc1 and are intended for the 4.13 merge
window.

regards
Suman

[PATCH 1/2] ARM: dts: am572x-idk: Enable the system mailboxes 5 and 6

[Suman Anna]

Enable the System Mailboxes 5 and 6 and the corresponding
child sub-mailbox (IPC 3.x) nodes for the AM572x IDK board.
This is needed to enable communication with the respective
remote processors IPU1, IPU2, DSP1 and DSP2 from the MPU.
