mailbox: ti-msgmgr: Operate mailbox in polled mode during system suspend

2022-03-13T01:33:30+00:00

During the system suspend path we must set all queues to operate in polled mode as it is possible for any protocol built using this mailbox, such as TISCI, to require communication during the no irq phase of suspend, and we cannot rely on interrupts there. Polled mode is implemented by allowing the mailbox user to define an RX channel as part of the message that is sent which is what gets polled for a response. If polled mode is enabled, this will immediately be polled for a response at the end of the mailbox send_data op before returning success for the data send or timing out if no response is received. Finally, to ensure polled mode is always enabled during system suspend, iterate through all queues to set RX queues to polled mode during system suspend and disable polled mode for all in the resume handler.

include/: replace HTTP links with HTTPS ones

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Signed-off-by: Alexander A.

mailbox: Introduce TI message manager driver

2016-03-21T15:03:15+00:00

Support for TI Message Manager Module. This hardware block manages a bunch of hardware queues meant for communication between processor entities. Clients sitting on top of this would manage the required protocol for communicating with the counterpart entities. For more details on TI Message Manager hardware block, see documentation that will is available here: http://www.ti.com/lit/ug/spruhy8/spruhy8.pdf Chapter 8.1(Message Manager) Signed-off-by: Nishanth Menon Signed-off-by: Jassi Brar
