Add bindings for F0/F3/G0/G4 clocks.
Introduce new rcc binding "st,stm32f0-rcc" binding
that describes RCC hardware blocks that don't have
"apb2-prescaler".
This binding also applies to G0.
Binding "st,stm32f0-pll-clock" is used for both F0
and F3 series.

Add a function that uses the JESD216 SFDP BFP DW16 Enter 4-Byte
Addressing parameter to put the device into 4-byte addressing mode if
one of the entry modes that's supported by the driver is available on
the device.
Perform the transition if SFDP data is provided (either by devicetree
or at runtime), or if a special devicetree property provides the entry
mode descriptor.

Provided nodes reflect the clock tree of each series.
Clock nodes are disabled by default but populated with default
start up configuration. Main reason is the we don't want to
impact boards using Kconfig based clock configuration for now.
Exception to these rules:
- syslck: Default enabled, clock frequency and clock source not
provided
- pll: clock source not provided
This is made on purpose so that errors are triggered if parameters
essential to the board configuration are not provided.

This CL adds a override mechanism for pwm module's input clock source
assignment. If the 'clock-bus' property exists, the NPCX_DT_PROP_ENUM_OR
macro function will return an enum upper token value. Otherwise, it
expands to default value in 'clocks' property.
For example, if the users want to select LFCLK as pwm0's input clock,
ths node can be overridden by adding 'clock-bus' property with an enum
string, "NPCX_CLOCK_BUS_LFCLK".
&pwm0 {
status = "okay";
clock-bus = "NPCX_CLOCK_BUS_LFCLK";
};

i2s1 is not present in all stm32f4 series. So moving the i2s1 node

files. Also in stm32f429zi, the sequence starts from i2s2, this commit
helps in having the right channel number.

The binding-template.yaml file has grown organically into something
that's out of control.
It makes too many 'see above' and 'see below' references to be read
comfortably, and we can't cross reference from YAML.
There are also many example DTS and YAML fragments scattered about in
comments, which cannot be syntax highlighted properly.
Fix that by overhauling the documentation into bindings.rst in the DT
guide. This will let us link to individual sections when answering
questions, allows us to cross-reference and use '.. code-block::',
etc.
A couple of things need to go to other pages.

Most of the Renesas RCar Gen3 based SoC contains a Cortex R7
processor.
This processor has access to the same memory mapped devices than
the Cortex-A5x cores.
- CPU operates upto 800MHz
- Can use ram area from 0x40040000 to 0x42000000
- Has 512 interrupts on GIC-400 compliant with Arm GICv2
Add support for r8a77951 as first SoC of this series which is also
known as H3 ES2.0 and is present present on different boards such as
Salvator and R-Car Starter Kit(H3ulcb).
This first SoC definition is just enough to print Hello World in a

Some SPI NOR devices, particularly Atmel and SST, power-up with block
protect bits set in the status register. These bits must be cleared
before any erase or program operation can succeed. However, blindly
clearing bits in SR is wrong as some of these are non-volatile and
control chip behavior, including quad-enable.
Add a devicetree flag to identify device-specific BP bits in the status
register that should be cleared on startup only for devices that need
them, and when set do the clear during initialization.

Define the FLASH_CCFG memory region from a devicetree partition instead
of from math in the linker file. Removing the special math case results
in the FLASH_CCFG region overlapping the FLASH region, but the linker
accepts this until the FLASH region actually starts placing variables
in the FLASH_CCFG region.
As a result, applications that don't fit in (FLASH_SIZE - 88) bytes will
still fail to link, just with an overlapping memory region error instead
of an overflow error.
