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
dts property.
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.

Meson6, Meson8, Meson8b and Meson8m2 are using a similar SDHC controller
IP which typically connects to an eMMC chip (because unlike the SDIO
controller the SDHC controller has an 8-bit bus interface).
On Meson8, Meson8b and Meson8m2 the clock inputs are all the same.
However, Meson8m2 seems to have an improved version of the SHDC
controller IP which doesn't require the driver to wait manually for a
flush of a DMA transfer. Thus every SoC has it's own compatible string
so if more difference are discovered they can be implemented.

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

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.
