efbfd448e5 firmware: ti_sci: Always request response from firmware
TI-SCI firmware will only respond to messages when the
TI_SCI_FLAG_REQ_ACK_ON_PROCESSED flag is set. Most messages
already do this, set this for the ones that do not.

32aebcf244 firmware: ti_sci: Fix TISCI mailbox receive timeout handling
An earlier commit converted the TISCI receive timeouts to be specified
in ms rather than us however it failed to take this change into account
when passing the actual timeout to be used when invoking the mailbox
receive API. This leads to the actual timeout to be 1,000 times shorter
than expected and as a result certain TISCI operations would fail.

Fix the issue by converting the timeout declared in ms to us on the fly
as expected by the respective API.

826eb74015 firmware: Add support for querying msmc memory
DMSC can use certain amount of msmc memory available in the
system. Also certain part of msmc memory can be marked as L3
cache using board config. But users might not know what size
is being used and the remaining available msmc memory. In order
to fix this TISCI protocol provides a messages that can query
the available msmc memory in the system. Add support for this
message.

fd6b40b1ba firmware: ti_sci: Add support for NAVSS resource management
Texas Instruments' System Control Interface (TI-SCI) Message Protocol
abstracts management of NAVSS resources, like PSI-L pairing and
unpairing, UDMAP tx/rx/flow configuration and Rings.

This patch adds support for requesting and configuring such resources
from TI-SCI firmware.

ccbc8b2fdd firmware: ti_sci: Add support for processor control services
TI-SCI message protocol provides support for controlling of various
physical cores available in SoC. In order to control which host is
capable of controlling a physical processor core, there is a processor
access control list that needs to be populated as part of the board
configuration data.

Introduce support for the set of TI-SCI message protocol apis that
provide us with this capability of controlling physical cores.

f369b0f26c firmware: ti_sci: Add support for reboot core service
Since system controller now has control over SoC power management, it
needs to be explicitly requested to reboot the SoC. Add support for
it.

9b87181fd2 firmware: ti_sci: Add support for clock control
In general, we expect to function at a device level of abstraction,
however, for proper operation of hardware blocks, many clocks directly
supplying the hardware block needs to be queried or configured.

Introduce support for the set of SCI message protocol support that
provide us with this capability.

32cd25128b firmware: Add basic support for TI System Control Interface (TI SCI) protocol
Texas Instrument's System Control Interface (TI SCI) message protocol is
used in Texas Instrument's System on Chip (SoC) such as those in the K3
family AM654 SoC to communicate between various compute processors with
a central system controller entity.

The TI SCI message protocol provides support for management of various
hardware entities within the SoC. Add support driver to allow
communication with system controller entity within the SoC using the
mailbox client.

This is mostly derived from the TI SCI driver in Linux located at
drivers/firmware/ti_sci.c.
