The RZ/G2H (r8a774e1) comes with two clusters of processors, similarly to
the r8a774a1. The first cluster is made of A57s, the second cluster is made
of A53s.
The operating points for the cluster with the A57s are:
Frequency | Voltage
----------|---------
500 MHz | 0.82V
1.0 GHz | 0.82V
1.5 GHz | 0.82V
The operating points for the cluster with the A53s are:
Frequency | Voltage
----------|---------
800 MHz | 0.82V
1.0 GHz | 0.82V
1.2 GHz | 0.82V
This patch adds the definitions for the operating points to the SoC
specific DT.

Beacon EmebeddedWorks, formerly Logic PD is introducing a new
SOM and development kit based on the RZ/G2M SoC from Renesas.
The SOM supports eMMC, WiFi and Bluetooth, along with a Cat-M1
cellular radio.
The Baseboard has Ethernet, USB, HDMI, stereo audio in and out,
along with a variety of push buttons and LED's, and support for
a parallel RGB and an LVDS display.

We can now probe devices with ti-sysc interconnect driver and dts
data. Let's drop the related platform data and custom ti,hwmods

As we're just dropping data, and the early platform data init
is based on the custom ti,hwmods property, we want to drop both
the platform data and ti,hwmods property in a single patch.

The watchdog timers have been added for the IPU and DSP remoteproc
devices for the OMAP5 uEVM board. The following timers (same as the
timers on OMAP4 Panda boards) are used as the watchdog timers,
DSP : GPT6
IPU : GPT9 & GPT11 (one for each Cortex-M4 core)
The MPU-side drivers will use this data to initialize the watchdog
timers, and listen for any watchdog triggers. The BIOS-side code
needs to configure and refresh these timers properly to not throw
a watchdog error.
These timers can be changed or removed as per the system integration
needs, alongside appropriate equivalent changes on the firmware side.

The BIOS System Tick timers have been added for the IPU and DSP
remoteproc devices for the OMAP5 uEVM boards. The following timers
(same as the timers on OMAP4 Panda boards) are chosen:
IPU : GPT3 (SMP-mode)
DSP : GPT5
IPU 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 timers are optional, but are mandatory to support 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, alongside
equivalent changes on the firmware side.

The CMA reserved memory nodes have been added for the IPU and DSP
remoteproc devices on the OMAP5 uEVM board. These nodes are assigned
to the respective rproc device nodes, and both the IPU and DSP remote
processors are enabled for this board.
The current CMA pools and sizes are defined statically for each device.
The starting addresses are fixed to meet current dependencies on the
remote processor firmwares, and 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.

OMAP5, like OMAP4, also has two remote processor subsystems,
DSP and IPU. The IPU subsystem though has dual Cortex-M4
processors instead of the dual Cortex-M3 processors in OMAP4,
but otherwise has almost the same set of features. Add the
DT nodes for these two processor sub-systems for all OMAP5
SoCs.
The nodes have the 'iommus', 'clocks', 'resets', 'firmware' and
'mboxes' properties added, and are disabled for now. The IPU node
has its L2 RAM memory specified through the 'reg' and 'reg-names'
properties. The DSP node doesn't have these since it doesn't have
any L2 RAM memories, but has an additional 'ti,bootreg' property
instead as it has a specific boot register that needs to be
programmed for booting.
These nodes should be enabled as per the individual product
configuration in the corresponding board dts files.

The compatible property for the DSP node is updated to match
the OMAP remoteproc bindings. The node is moved from the soc
node to the ocp node to better reflect the connectivity from
MPU side.
The node is updated with the 'ti,bootreg', 'clocks', 'resets',
'iommus', 'mboxes' and 'firmware' properties. Note that the
node does not have any 'reg' or 'reg-names' properties since
it doesn't have any L2 RAM memory, but only Unicaches.

The commit d41e530409 ("clk: ti: omap5: cleanup unnecessary clock
aliases") has cleaned up all timer_sys_ck clock aliases and retained
only the timer_32k_ck clock alias. The OMAP clocksource timer driver
though still uses this clock alias when reconfiguring the parent
clock source for the timer functional clocks, so add these clocks
to all the timer nodes except for the always-on timers 1 and 12.
This is required by the OMAP remoteproc driver to successfully
acquire a timer and configure the source clock to be driven from
timer_sys_ck clock.
