With this, the clocksource driver can setup the timers properly.

From: Suman Anna <s-anna@ti.com>
The DRA7xx family of SOCs have two IPUs and upto two DSP
processor subsystems in general. The IPU processor subsystem
contains dual-core ARM Cortex-M4 processors, while the DSP
processor subsystem is based on the TI's standard TMS320C66x
DSP CorePac core. The IPUs are very similar to those on OMAP5.
Two IPUs and one DSP processor subsystems is the most common
configuration. The processor device DT nodes have been added
for these processor subsystems, with the internal memories
added through 'reg' and 'reg-names' properties. The IPUs only
have an L2 RAM, whereas the DSPs have L1P, L1D and L2 RAM
memories.
NOTE:
1. The nodes do not have any mailboxes, timers or CMA regions
assigned, they should be added in the respective board dts
files.
2. The nodes haven been disabled by default and the enabling
of these nodes is also left to the respective board dts
files.

The DRA7xx family of SoCs can contain upto two identical DSP
processor subsystems. The second DSP processor subsystem is
present only on the DRA74x/DRA76x variants. The processor
device DT node has therefore been added in disabled state for
this processor subsystem in the DRA74x specific DTS file.
NOTE:
1. The node does not have any mailboxes, timers or CMA region
assigned, they should be added in the respective board dts
files.
2. The node should also be enabled as per the individual product
configuration in the corresponding board dts files.

The aliases uses the stem "rproc". The aliases are defined
in the order of the most common processors on the DRA74x
family.
The aliases can be overridden, if needed, in the respective
derivative board dts files.

The System Mailboxes 5 and 6 and their corresponding child sub-mailbox
(IPC 3.x) nodes are enabled in each of the DRA7xx and AM57xx board
dts files individually at present. These mailboxes enable the Remote
Processor Messaging (RPMsg) communication stack between the MPU host
processor and each of the IPU1, IPU2, DSP1 and DSP2 remote processors.
Move these nodes into two common dtsi files - dra7-ipu-dsp-common and
dra74-ipu-dsp-common files, which are then included in various board
dts files. These files can be used to add all the common configuration
properties (except memory data) required by remote processor nodes.
The memory pools and the remote processor nodes themselves are to be
enabled in the actual board dts files. The first file is to used by
platforms using DRA72x/DRA71x/AM571x/AM570x SoCs, and the second file
is to be used by platforms using DRA74x/DRA76x/AM572x/AM574x SoCs.
The second file includes the first file and contains additional data
only applicable for DSP2 remote processor.

Add the required 'mboxes' property to all the IPU and DSP remote
processors (IPU1, IPU2, DSP1 and DSP2) in the two available common
dtsi files - dra7-ipu-dsp-common and dra74-ipu-dsp-common dtsi files.
The latter file is for platforms having DRA74x/DRA76x/AM572x/AM574x
SoCs which do have a DSP2 processor in addition to the other common
remote processors. The common data is added to the former file, and
the DSP2 only data is added to the latter file.
The mailboxes are required for running the Remote Processor Messaging
(RPMsg) stack between the host processor and each of the remote
processors. Each of the remote processors uses a single sub-mailbox
node, the IPUs are assumed to be running in SMP-mode. The chosen
sub-mailboxes match the values used in the current firmware images.
This can be changed, if needed, as per the system integration needs
after making appropriate changes on the firmware side as well.

From: Suman Anna <s-anna@ti.com>
The BIOS System Tick timers have been added for all the IPU and
DSP remoteproc devices in the DRA7 SoC family. The data is added
to the two common dra7-ipu-dsp-common and dra74-ipu-dsp-common
dtsi files that are included by all the desired board files. The
following timers are chosen, as per the timers used on the current
firmware images:
IPU2: GPTimer 3
IPU1: GPTimer 11
DSP1: GPTimer 5
DSP2: GPTimer 6
The timers are optional, but are mandatory to support advanced device
management features such as power management and watchdog support.
The above are added to successfully boot and execute firmware images
configured with the respective timers, images that use internal
processor subsystem timers are not affected. The timers can be
changed or removed as per the system integration needs, if needed.
Each of the IPUs has two Cortex-M4 processors, and is currently
expected to be running in SMP-mode, so only a single timer suffices
to provide the BIOS tick timer. An additional timer should be added
for the second processor in IPU if it were to be run in non-SMP mode.
The timer value also needs to be unique from the ones used by other
processors so that they can be run simultaneously.

The CMA reserved memory nodes have been added for all the IPU and DSP
remoteproc devices on DRA7 EVM board. These nodes are assigned to the
respective rproc device nodes, and all the IPU and DSP remote processors
are enabled for this board.
The current CMA pools and sizes are defined statically for each device.
The CMA pools and sizes are defined using 64-bit values to support LPAE.
The starting addresses are fixed to meet current dependencies on the
remote processor firmwares, and this will go away when the remote-side
code has been improved to gather this information runtime during its
initialization.
An associated pair of the rproc node and its CMA node can be disabled
later on if there is no use-case defined to use that remote processor.

rproc nodes are also enabled to enable these processors on the
DRA72 EVM rev C board.

DSP1 remoteproc devices on DRA71 EVM board. These nodes are assigned to
the respective rproc device nodes, and both the IPUs and the DSP1 remote
processors are enabled for this board.

The CMA pools and sizes are defined using 64-bit values to support LPAE.
The starting addresses are fixed to meet current dependencies on the

From: Suman Anna <s-anna@ti.com>
The watchdog timer information has been added to all the IPU and DSP
remote processor device nodes in the DRA7xx/AM57xx SoC families. The
data has been added to the two common dra7-ipu-dsp-common and
dra74-ipu-dsp-common dtsi files that can be included by all the
desired board files. The following timers are chosen as the watchdog
timers, as per the usage on the current firmware images:
IPU2: GPTimers 4 & 9 (one for each Cortex-M4 core)
IPU1: GPTimers 7 & 8 (one for each Cortex-M4 core)
DSP1: GPTimer 10
DSP2: GPTimer 13
Each of the IPUs has two Cortex-M4 processors and so uses a timer
each for providing watchdog support on that processor irrespective of
whether the IPU is running in SMP-mode or non-SMP node. The chosen
timers also need to be unique from the ones used by other processors
(regular timers or watchdog timers) so that they can be supported
simultaneously.
The MPU-side drivers will use this data to initialize the watchdog
timer(s), and listen for any watchdog triggers. The BIOS-side code on
these processors needs to configure/refresh the corresponding timer
properly to not throw a watchdog error.
The watchdog timers are optional in general, but are mandatory to
be added to support watchdog error recovery on a particular processor.
These timers can be changed or removed as per the system integration
needs, alongside appropriate equivalent changes on the firmware side.

If there are no dependencies between the pending driver fixes and
the dts changes I see no reason to not merge the dts changes.

OK thanks for checking that.

OK. The combining of common features can be done in later patches
too.

Yeah, no hard dependencies as such, just that things won't work properly
before they are in.

Applying these all into omap-for-v5.8/dt thanks.
