This driver is mostly the initial seed for further implementation of a
real clock driver.
It doesn't allow the user to choose the clock source for the various
peripherals. The driver hardcodes some sane values.
Note that for now, the driver snps,designware-i2c does not support
"clocks" attribute. So this patch hardcode the clock configuration in
the init of the clock driver.

This serves two main purposes:
- change the CPU clock via devicetree nodes
- provide the APB frequency to device drivers via the clock driver
interface
Theoretically this could also support choosing between the available
clock sources, but right now we only support LPOSC0 going into PLL0,
going into AHB.
Turning the PLL back off is also not supported since the only current
use case is to set the PLL frequency, turn it on, and switch the AHB
over to it.

This includes:
1) Source containing helper functions, each
implementing a command from the clock management
protocol.
2) A clock controller driver making use of said
helper functions and implementing the clock
subsystem API.
3) A DT binding for clock protocol node.

Add a new driver for the AUXPLL peripheral found in some new Nordic
SoCs, e.g. nRF54H20. AUXPLL is used to clock some peripherals like e.g.
CAN. Note that driver is implemented natively as Nordic HAL lacks
definitions for the AUXPLL IP, this may be changed once these become
available.
Note that usage of nrf_auxpll_config_set generates unnecessary extra
assembly code compared to the proposed API in
https://github.com/zephyrproject-rtos/hal_nordic/pull/185 which
guarantees static initialization and single write access, possible in
the Zephyr context. However, current solution has been enforced until
further discussion on raw access APIs takes place.

The clock controller is a singleton controller for all the system-level
clocks (XOSC, PLL, CGM, etc) to provide run-time information to the
peripheral device drivers about the module's clocks.
Clock configuration is not yet supported.

Add fixed-clock clock control driver. This is a first step towards

Since the change is hidden behind a Kconfig enable this is opt-in
for now.

Unify the drivers/*/Kconfig menuconfig title strings to the format
"<class> [(acronym)] [bus] drivers".
Including both the full name of the driver class and an acronym makes
menuconfig more user friendly as some of the acronyms are less well-known
than others. It also improves Kconfig search, both via menuconfig and via
the generated Kconfig documentation.

This patch adds a clock control driver for GD32 platforms. It is
important to note that the driver is only able to handle peripheral
clocks, but not "system clocks" (e.g. PLL settings, SYS_CK, etc.). On
some similar platforms (STM32) this task is embedded in the same clock
driver, performed at init time but with no options to do any
manipulation at runtime via the API calls. The clock control API as-is
is really orthogonal to "system clocks", and it is arguably a bad idea
to embed system clock init code in a clock control driver. It can be
done at SoC level still using Devicetree as a source of hardware
description/initial configuration.

AST10x0 series SOCs provide the clock controller through the syscon
hardware block. The current driver supports the clock gating capability
for the hardware IPs embedded in the SOC. Each clock source has a
clock ID that can simply map to a bit in syscon registers CLK_STOP_CTRL0
(group 0) or CLK_STOP_CTRL1 (group 1). There are some clock sources
that don't have associated clock gating control, which are always on,
are grouped to into group 2.

Simple driver that allows one to choose the clock speed of xtensa cores.
It's basically a shim layer on top of SOC level driver.
Also, a really simple test case was added, mainly to ensure things are

Refactors all of the clock control drivers to use a shared driver class
initialization priority configuration,
CONFIG_CLOCK_CONTROL_INIT_PRIORITY, to allow configuring clock control
drivers separately from other devices. This is similar to other driver
classes like I2C and SPI.
Most drivers previously used CONFIG_KERNEL_INIT_PRIORITY_OBJECTS or
CONFIG_KERNEL_INIT_PRIORITY_DEVICE, therefore the default for this new
option is the lower of the two, which means earlier initialization.
The even lower defaults for STM32 and Arm Beetle are preserved by
SoC-family level overrides.

Implement a clock control driver for Microchip MEC172x handling
configuring the 32 KHz input sources for the PLL and peripheral-32k
clock domains. MEC172x differs from MEC152x. MEC152x had one 32K source
for both PLL and peripherals. MEC172x allows the two domains to use
independent 32 KHz sources. Device tree updated to provide addresses
of hardware used by the driver.

- Support PLL for Higher Frequencies 80,160,240 MHz
- Support XTAL Frequencies 26MHz, 40MHz
- Clock Driver can't be disabled, because all of the other drivers
will depend on it to get their operating Frequency based on chosen
clock source (XTAL/PLL).
- Add needed references to BBPLL i2c bus ROM functions.
- Add `rtc` node to Device Tree.
- Since All Peripherals Frequency is depending on CPU_CLK Source,
