[PATCH 0/5] Add DRA7 sub-mailboxes for 4.4

[PATCH 0/5] Add DRA7 sub-mailboxes for 4.4

[Suman Anna]

Hi Tony,

This series adds the sub-mailbox nodes and enable them for each
of the TI DRA7 boards. These are the basic mailbox configuration
nodes required by client users (remoteproc) to communicate with
the various IPU and DSP processor devices on DRA74x and DRA72x
SoCs using the TI IPC 3.x software foundation on the remote
processor firmwares. The mailboxes used are unfortunately
hardcoded in the TI IPC 3.x software, and hence the weird
usage of Mailbox 5 and 6 rather than starting from Mailbox 1.

Any third-party or derived boards can use their own configuration
if running their own IPC stack, and that can be done by overwriting
the properties or by using different sub-mailbox nodes altogether.
The actual enablement of nodes is therefore done in the respective
board DTS files.

Patches are based on 4.3-rc1 and are intended for the 4.4 merge
window.

regards
Suman

[PATCH 1/5] ARM: dts: DRA74x: Add IPC sub-mailbox nodes for all IPUs & DSPs

[Suman Anna]

Add the sub-mailbox nodes that are used to communicate between
MPU and the remote processors IPU1, IPU2, DSP1 and DSP2.

The sub-mailbox nodes utilize the System Mailbox instances 5 and 6.
These sub-mailbox nodes are added to match the hard-coded mailbox
configuration used within the TI IPC 3.x software package. The
Dual-Cortex M4 IPU1 and IPU2 processor sub-systems are assumed to
be running in SMP-mode, and hence only a single sub-mailbox node
is added for each.

All these sub-mailbox nodes are left in disabled state, and should
be enabled (and modified if needed) as per the individual product
configuration in the corresponding board dts files.

[PATCH 2/5] ARM: dts: DRA72x: Add IPC sub-mailbox nodes for IPU1, IPU2 & DSP1

[Suman Anna]

Add the sub-mailbox nodes that are used to communicate between
MPU and the remote processors IPU1, IPU2 and DSP1. These match the
respective node definitions on DRA74x to maintain compatibility for
the equivalent remote processors. There is no DSP2 on DRA72x, and
so the corresponding sub-mailbox node is not added.

These sub-mailbox nodes are added to match the hard-coded mailbox
configuration used within the TI IPC 3.x software package. The
Dual-Cortex M4 IPU1 and IPU2 processor sub-systems are assumed to
be running in SMP-mode, and hence only a single sub-mailbox node
is added for each.

All these sub-mailbox nodes are left in disabled state, and should
be enabled (and modified if needed) as per the individual product
configuration in the corresponding board dts files.

Thanks applying all into omap-for-v4.4/dt.
