Dave Gerlach cdd5de500b soc: ti: Add wkup_m3_ipc driver
Introduce a wkup_m3_ipc driver to handle communication between the MPU
and Cortex M3 wkup_m3 present on am335x.

This driver is responsible for actually booting the wkup_m3_rproc and
also handling all IPC which is done using the IPC registers in the control
module, a mailbox, and a separate interrupt back from the wkup_m3. A small
API is exposed for executing specific power commands, which include
configuring for low power mode, request a transition to a low power mode,
and status info on a previous transition.

Say y here to support the Keystone multicore Navigator Queue
Manager support. The Queue Manager is a hardware module that
is responsible for accelerating management of the packet queues.
Packets are queued/de-queued by writing/reading descriptor address
to a particular memory mapped location in the Queue Manager module.
If unsure, say N.

Say y tp enable support for the Keystone Navigator Packet DMA on

Queue Manager Sub System.

TI AM33XX and AM43XX have a Cortex M3, the Wakeup M3, to handle
low power transitions. This IPC driver provides the necessary API
to communicate and use the Wakeup M3 for PM features like suspend
resume and boots it using wkup_m3_rproc driver.
